4th meeting WG Sediments in Circular Economy

4th meeting SedNet WG Sediments in Circular Economy: 15-16 April 2020

Due to Covid-19 this meeting was organised online in two sessions:

– 15 April – from 9 to 12 hrs Glasgow time (10 to 13 hrs for most others):
* PFAS and
* mass stabilization
– 16 April – 9 to 12 hrs Glasgow time (10 to 13 for most others):
* upcoming example projects

Summary meeting report
Twenty-one participants representing eleven countries took part in the web sessions to exchange collaborative ideas on Circular Economy (CE) practice and opportunities, and on two focus topics (1) stabilisation and beneficial use and (2) the PFAS problem in sediments).

Two group sessions were led on priority topics identified on WGCE2:

  • Beyond the initial “mass balance” approach to CE, need for defining ‘value’ to the ecological potential of sediment – and Incorporating CO2 and CH4 balance of sediment use in CE balance and funding, benefit or risk?
  • Setting up a synthetic catalogue of beneficial use options.

The outcome of WGCE3 session on “Clear definitions of concepts (beneficial use, valorisation, reuse, sustainability)” was validated.

A first draft of the WG white paper will be initiated with the outcome.

Future meetings are still uncertain with COVID-19 sanitary issues but according to travel possibility,

  • One will include both field visits (pilots, plants and workshops) and focus discussions,
  • The other one can be organised in live or web format, and comprise topic discussions, white paper and policy/RTD support documents elaboration.

Both may comprise project proposals workshops if the EU RTD agenda is favourable.

WGCE5 should be set up in October (7th and 8th) in Glasgow if travel is allowed, including site visits as expected for WGCE4.

WGCE6 will be organised in connexion with the SedNet 2021 conference in Lille. The invited talk by a USEPA Great Lakes National Program Office speaker on sediment remediation with beneficial use experience in the US should be on this opportunity, to ensure maximum audience.

Sediment flagged up in Water Fitness Check

The Water Fitness Check has been published Thursday 12 December 2019. This fitness check is a comprehensive policy evaluation of four Directives on integrated water management: WFD, EQS, GD and FD. It assesses whether the Directives are fit for purpose. It flagged up chemicals as key area where there is room to improve and to achieve better results. At several places it mentions the binding to, and accumulation and monitoring of chemicals (pollutants) in sediments.

However, the fitness check also flags up several other sediment and water related issues:

Hydromorphology is a term used to describe the hydrological and geomorphological characteristics (including continuity) of rivers, lakes, and coastal and transitional waters, including the underlying processes from which they result. Water and sediments interact at different scales and shape the physical environment, determining physico-chemical processes and providing a physical habitat for the biota. Hydromorphological alterations are associated with water storage, irrigation, flood protection, navigation, urban development and changes in land use. Hydromorphological pressures reported by Member States include physical alterations (26%), dams, barriers and locks (24%), hydrological alterations (7%) or other hydromorphological alterations (7%)” (page 21 of the fitness check)


A further area is sediments. Sediments are transported from river basins to marine areas, but in many river basins there are insufficient or no management measures for sediments at river basin level. This can be an issue for marine habitats when the supply of sediment is insufficient to prevent or compensate for coastal erosion. The MSFD status assessment places specific emphasis on contaminants in sediments. In contrast, the WFD, while allowing Member States to set EQSs for sediments, addresses such contamination primarily in the context of the trend-monitoring requirement under the EQSD. Some stakeholders, in particular from the navigation sector, expressed concern that the interplay between the WFD and MSFD does not function well enough on sediment management.” (page 86 of the fitness check)


To achieve the WFD’s objectives, Member States need to draw up and implement the necessary measures. Among these are demand management and coordination with other plans and programmes, including land management and soil protection action aimed at reducing the risk of desertification. For more on this issue, see the European Court of Auditors’ report on desertification. Measures to reduce sediment from soil erosion and surface run-off are also included in the second RBMPs and have been reported for 34 RBDs.”  (page 171 of the fitness check)


Navigation activities can also affect chemical status, as ships, boats and the infrastructure to support them can cause a range of environmental problems. In particular, they can lead to direct emissions of contaminants by boats, but also to indirect contamination by remobilisation of contaminated sediments. The use of anti-fouling products has in particular led to contamination of water. Due to aquatic toxicity and persistence, the use of organotin compounds in anti-fouling coatings has been banned since 2008.” (page 173 of the fitness check)


Extractive activities are placed where the natural resources exist, with no or very limited possibilities to be relocated. In some cases, they involve high concentrations of certain elements due to natural background levels and/or diffuse pollution. If suitable measures are not implemented, mining activities can affect freshwater ecosystems in different ways through changes in the groundwater and surface water hydrology, or through the release of chemicals and/or sediments in water. Impacts on water will depend on the type of mineral, mining practices, substances used at the processing stage, and the way mining waste is handled. If not properly addressed, these impacts can occur during the exploitation of the mine, but also long after the cessation of activity.” (page 175 of the fitness check)

SedNet member WFD & FD strategic coordination group

On 18 September 2019 the European Sediment Network SedNet became as NGO official member of the Strategic Coordination Group (SCG, see figure) of the Common Implementation Strategy (CIS) of the Water Framework Directive (WFD) and Floods Directive (FD).

Through its SCG membership SedNet gets optimal opportunities to continue to raise attention for sediment management and bring in sediment management expertise and experience in support of European water policy implementation. This is needed as SedNet stated in its 2017 policy brief that European water policy objectives will only be achieved by also integrating sediment in River Basin Management Planning.

The role of the SCG is the co-ordination of the different working groups and activities under the common strategy such as the work in the pilot river basins. The strategic co-ordination group will evaluate the outcome of the different working groups and prepare documents and reports for the Water Directors’ meetings and give guidance to the key activities. The main objectives of the CIS are to ensure a better implementation of the water legislation and to promote the integration of water related issues in other environmental policies, as well as in other sectoral policies such as agriculture, transport or energy (Rules of procedure for the SCG under the WFD and FD CIS, June 2019).


Guidance document on sediment management in support of the WFD

The CIS work program for ECOSTAT for 2019-2021 includes the topic “sediment”, with the main aim to exchange information and best practice between Member States and stakeholders. A workshop was organised by ECOSTAT and SedNet in April 2019 in Dubrovnik, which led to the conclusion that there was a need to draft a CIS guidance document on sediment management in the context of the WFD, in order to share good practices, common languages and provide common interpretation on the role of sediment management in the context of the WFD.

A core-group was nominated to coordinate this work. The work will be divided into 4 sub-groups to draft each chapter of the document. The document will be divided in 4 chapters – Catchment Scale Analysis; Sediment Quantity; Sediment Contamination; Integrated Sediment Management Planning. For each chapter, a group of experts will be established to draft and review the content. Each chapter is expected to be around 20 pages and to focus on key messages, with reference to other documents/reports for more precise information. In addition to the main text of the guidance, a library of existing information (publications, reports, guidance, management plans, case studies, …) will be set up and maintained.

SedNet steer group members participate in the core-group as well as the sub-groups. For more information please contact Jos Brils, the SedNet delegated member to the WFD CIS SCG and ECOSTAT sediment core-group.


Start of SedNet Working Group “Education-Science-Policy Interfacing & Sediment Management Concepts” (WG ESPI-SMC)

Since a long time SedNet wishes to compile all relevant experience in sediment management in a guidance document. Also SedNet would like to communicate with and educate students and other interested people about sediment management. In this way our work will be better understood and appreciated.

To achieve this SedNet organized the first workshop/meeting of the SedNet Working Group “Education-Science-Policy Interfacing & Sediment Management Concepts” (WG ESPI-SMC) on Wednesday 20th and Thursday 21st of November 2019 in Madrid. During the workshop experiences of setting up sediment management concepts of the Rhine, Elbe and Scheldt were exchanged. Also the lessons learned of making a sediment guidance document made in the USA in 2005 were presented. A rough plan of action to write out a SedNet guidance document about how to set up sediment management concepts was made. This guidance document will be developed by the WG ESPI-SMC in 2020-2021 and will be supplementary to the guidance document that the European Commission (ECOSTAT) is developing in the same period.

Also first ideas were gathered to create a “Sediment (serious) game”. A draft of this game will be developed and tested in 2020 by the WG ESPI-SMC. We hope to “play” the game on the next SedNet conference in 2021. If successful, it would be nice to create after that a professional online version of the game in different languages to teach secondary school students and university students the principals of good sediment management. Next to that the WG ESPI-SMC hopes to create an educational learning package. But the WG ESPI-SMC also wants to create communication tools like movies about good sediment management practices.

Workshop of the SedNet Working Group on Sediment Quality

elucidating The Role of Ecotoxicological Data in Sediment Quality and Dredged Material Assessment Frameworks

We would like to invite interested experts from academia, industry/business and government to join us in Rome on 10-11 March 2020, to discuss experiences, challenges and approaches regarding the use of biotesting and ecotoxicological data in the assessment of sediment and dredged material quality. In addition to the concentration of hazardous substances in sediments, their effects on the biological community is gaining attention in quality assessment. Effects can be addressed e.g. by direct biotesting of sediments and/or the use of ecotoxicologically based sediment quality criteria.  Among a variety of different approaches and related issues that come with their application in Europe, we will focus on 4 topics in this workshop. We would like to

  • review on how ecotoxicological testing is applied in sediment quality and dredged material assessment frameworks in different countries. Please share your experiences and problems with us. Let us discuss opportunities and challenges and whether there is a way – or indeed a need – for international harmonization of biotesting sediments.
  • reflect on sediment quality criteria and their efficiency to protect the environment and its living resources. We would especially like to look at the OSPAR EACs (Environmental Assessment Criteria) and threshold levels applied in the Mediterranean Sea in the context of risks from hazardous substances in the marine environment.
  • discuss possibilities and methods to back calculate EQSs for the WFD to produce sediment quality guidelines
  • shed a light on the applicability of passive sampling methodology to derive thresholds suitable for assessment purposes.

The workshop will be free of charge and will last from midday on March 10 to the evening of March 11.

The number of participants will be restricted to 25 people. If you are interested, please contact Susanne Heise.


Update from SedNet Working Group Circular Economy

Twenty-five participants representing nine countries met in Bremen (DE) and Delfzijl (NL) last October to exchange on Circular Economy practice and opportunities, and visit operational sites.

A presentation on the port of Bremen dredged material management site allowed to discover low energy treatment in dewatering basins and on-site disposal, and the role of nature in processes when land is available. A visit to the Ecoshape pilot site in Delfzijl allowed to complement the observations and to discuss site instrumentation for monitoring, desalination issues and agricultural beneficial use opportunities.

Small group sessions were led on priority topics identified during the spring meeting of the WG:

  • Clear definitions of concepts (beneficial use, valorisation, reuse, sustainability)
  • Beyond the initial “mass balance” approach to CE, need for defining ‘value’ to ecological potential of sediment
  • Incorporating CO2 and CH4 balance of sediment use in CE balance and funding, benefit or risk?
  • Setting up a synthetic catalogue of beneficial use options.

A WG white paper can be initiated with the outcome.

The focus of the WG-meeting was on a System-analysis workshop. This system thinking method allows investigating overlooked or long term options, to the opposite of Business as usual strategies. Group work between participants was productive – and fun!

Future meetings will include both field visits (pilots, plants and workshops) and elaborating project proposals and policy/RTD support documents.

The fourth meeting of the SedNet Working Group on Circular Economy (WGCE4) might be set up in March or April 2020, possibly including invited talks by speakers on beneficial use experience in the US, and on binders for facilitating beneficiary use of sediments.

SURICATES pilot Port of Rotterdam

During the 3th meeting of the SedNet Working Group on sediment use in circular economy in Bremen/Delfzijl on 23 and 24 October 2019 the Dutch SURICATES pilot in the port of Rotterdam was presented. SURICATES is an EU INTERREG IV program on Sediment Uses as Resources In Circular And Territorial Economics. One of the pilot locations is Port of Rotterdam, where 200.000 tons of sediment (estimated dredged volume of 500.000 m3) is reallocated within the harbour. The purpose of the reallocation is to shorten the trip (alternative is reallocation at sea) and at the same time enhance the sedimentation at the river banks to stimulate nature development and enhance erosion protection. To avoid siltation and navigation problems in the harbour the reallocation is done shortly after dead tide, with an ebb flow to carry most of the sediments towards the sea (where is enhances the sediment balance for the beaches). To study the sediment behaviour new measuring techniques are being deployed:

  • Use of optical cables to measure the sediment transport at the reallocation site by measuring the sediment coverage on two ~1 km long cables
  • Use of rare earth elements in sediment to characterise the origin of the sediment, hence fingerprinting the distribution of the reallocated sediment as compared to the original sediments
  • Use of ADCP backscatter data to measure the transport and settling of the dredging flume after reallocation
  • Laboratory tests on the rheology in relation to the change in sediment properties when reallocated from a more fresh water into a more marine environment

The first results are that the sediment does not accumulate in the main shipping channel, also not in the reallocation area. The fingerprinting with rare earth elements demonstrate that indeed part of the sediment are settling on the banks. but the main target area (a constructed wetland) is not receiving enough sediment due to the position of the wetland in the inner curve of the channel while most sediments are transported in the outside curve of the river. This are first results. Most raw data is collected over the summer of 2019, when the reallocation took place. Processing of the data and lab tests will continue in 2020.

12th International SedNet Conference, Lille, France

The next SedNet conference will take place in Lille, early in 2021. Both the exact date and location are still to be decided, but we expect it will be a great event, following the successful Dubrovnik conference.

Lille is the capital city of Northern France, an historic and vibrant place with lots of research and education institutes. It is part of the NL-BE-FR EuroRegion, accessible by fast connexions from UK and Germany too.

Lille is a fantastic place for sediment topics, being surrounded by major ports (Boulogne, Calais, Dunkirk, Zeebrugge, Oostende, Antwerp, Gent, with Rotterdam not that far) and by a dense transboundary network of large waterways. We hope to be able to offer not only one, but at least two excursions during the conference.

The conference theme shall be: “Sediment Challenges and Opportunities with Climate Change, and Sustainable Development Goals”. It will allow a broad coverage of environmental topics, as well as circular economy issues. A provisional list of topics and sessions is as below: 

  • Climate change and sediments: direct and indirect consequences and opportunities. Sediments in a changing Environment
  • How can sediment management influence ecosystem services provision?
  • Circular economy – sediment as a resource. Remediation and uses / Building with Dredged Materials and/or Sediments
  • Sediment management concept and sediment policy. Policy for sediment management / transboundary sediments & innovative maintenance of river delta sea systems
  • Sediment quality guidance, sediment quality assessment. Assessment and analytical methods, quality guidance
  • How to deal with emerging substances / PFAS / microplastics 
  • Impacts of disturbed sediment continua and mitigation measures? Sediment balance / Understanding sediment fluxes and budgets on a river basin scale/ HORIZON Europe, Land use impact of sustainable sediment management
  • Sediments in the coastal-marine zone management and EU strategies (HORIZON Europe, Blue Growth, etc.)

Possible other topics include:

  • Sustainable food production and/or consumption solutions and their effect on sediments and climate change (and vice versa)
  • Sediments in historical and recent mining areas – effects of remedial measures

A call for abstracts will be issued early in 2020 – prepare your abstracts, and stay tuned!

We look forward to seeing you in Lille and to having a great time together.


Emerging environmental issues related to climate change

In collaboration with the journal Frontiers in Environmental Science, section Toxicology, Pollution and the Environment an article collection is being organized on “Emerging Issues Regarding the Intersection of Climate, Toxic Substances, and Environmental Health” (Guest Editors: Raul Perez Lejano, Kyung-Min Nam, Susanne Heise, Peter S Hooda). The aim of this project is to bring together international experts to provide a comprehensive view of this topic. Would you like to participate as a contributing author?

The full description of this project can be found here. The submission deadline is Jun 30, 2020.


Seeking a solution inside a problem: “Contaminated-sediments as a source of Hg-detoxifying marine bacteria for bioremediation”

The MER-CLUB Project “MERcury Clean-UP system based on Bioremediation by marine bacteria” has been recently funded by the European Commission Blue Economy EASME Call in the topic Blue Labs – Innovative solutions for maritime challenges.

Mercury (Hg) pollution is a critical problem worldwide with large socio-economic, environmental and health impacts. Industrial pollution, particularly from chloralkali plants, is destructive to the marine environment at local, regional and global scales, raising serious concerns for ecosystems and human health. International initiatives, such as the Minamata Convention, are seeking to reduce Hg in the environment, forcing engaged parties to reduce emissions and remediate contaminated sites. In line with the latest objective, MER-CLUB aims at delivering a Hg clean-up system based on marine bacteria that can be used for bioremediation of marine sediments.

Marine microorganisms hold the genetic potential for Hg detoxification and may represent an economical and highly efficient alternative for decontamination. Using recent advances in environmental genomics, cell sorting and Hg stable isotope tracing, MER-CLUB aims at identifying strains and consortia with potential for Hg bioremediation in marine sediments from the Baltic, Mediterranean and the Atlantic. Therefore, MER-CLUB will target the largely unexplored diversity of marine Hg detoxifiers and the isolation and functional characterization of novel detoxifying marine strains or consortia, with the ultimate aim of designing a clean-up system based on immobilized bacteria able to operate in dredged marine sediments.

This new European project, coordinated by AZTI and ongoing since 1st November 2019, will be developed by a consortium of high-level international research groups specialized in marine microbiology, metagenomics, environmental assessment, and mercury biogeochemistry from Spain (AZTI, CSIC, UAB), Sweden (SLU), France (UPPA) and Germany (GMBU). The project also includes the participation of a SME (AFESA Medio Ambiente S.A.) which is currently involved in the decontamination of several chlor-alkali plants.

The project has been launched in the EASME kick-off meeting (Brussels, 5 December 2019) by the coordinator team from AZTI.

If you want to know more about MER-CLUB, please do not hesitate to email the project coordinator Dr. Laura Alonso-Sáez or follow the MER-CLUB updates at www.mer-club.eu and social media.


Sediment Classification and Management Decisions – in situ and ex situ

In 2003, den Besten et al.[1] provided an overview over different biological effect-based sediment quality assessments in Europe and concluded that there was a considerable difference between European countries in the way sediment quality guidelines (SQGs) were derived and implemented. Furthermore, the extent to which biological data were integrated in frameworks varied a lot and ranged with regard to dredged material assessment from “none” to “part of a decision support system”. Between 2003 and today, national frameworks will have changed due to new information on SQGs, new analyses methods, or due to different political incentives. In order to discuss the different current national approaches and trends on sediment and dredged material assessment in regulatory frameworks, a workshop was initiated by the Workgroup Sediment Quality of SedNet in cooperation with the project Sullied Sediments. The report has now been published and can be downloaded via this link.

Sullied Sediments project about to conclude

The Interreg-project Sullied Sediments (2017-2020) has finished its sampling period and now heads towards its conclusion phase. At 3 watershed, 7 sampling surveys were performed of the course of 2 years at the same time: Elbe and Humber catchment and Scheldt river basin district. Three sampling sites at each watershed had been chosen with respect to the potential impact of waste water treatment plants, due to the special focus of the project on Watch List chemicals. These are currently not regulated under the European Water Framework Directive but introduced into our waterways as a result of our day-to-day activities and through industry. Regardless of the source, they accumulate in the sediments in our rivers and canals.

Sullied Sediments gathered data on old and new sediment contaminants in sediments, their ecotoxicological effect and on the health of the biological community at the respective sites. These data in combination with new analytical methods and assessment tools will be used to inform water sector partners across the North Sea Region and enable them to make better decisions with regard to the management, removal and disposal of sediments, thereby reducing economic costs to private and public sector organisations, and the impact of these pollutants on the environment.

The expert system for making decisions on contaminated sediments and dredged material will be presented to interesting parties next spring via a webinar. Please watch out for announcements on the Sullied Sediments Website  or the SedNet website. For further information on the project, please contact Annabel Hanson or the project lead Jeanette Rotchell. For information on the expert system for decision making, contact Susanne Heise.

2nd Session SedNet Working Group Sediments in Circular Economy

The 2nd session of the SedNet WG on Circular Economy and Sediments took place on 2 April, the day before the SedNet conference. It was followed by a short joint session with the WG Sediment Quantity. 22 participants attended the meeting.

WG CE activities include:

  • Exchanges and open discussions on beneficial use options, sustainability (environmental, social and economic benefits), how to take into account external benefits in the economic balance, find different ways to answer the question ‘How to convince policy makers’ ? Beneficial use should not be a goal in itself but a substitute to primary materials extraction,
  • Gathering information from other groups (CEDA, PIANC) and events (AquaConsoil), and cooperation opportunities,
  • Submitting communication on good practice to the EU stakeholders platform on CE
  • Supporting RTD initiatives, especially trying to include Sediments topics in incoming Horizon, ERDF and Life call texts, and favouring the constitution of partnerships,
  • Connecting with SedNet “Sediment quantity” WG to exchange information and perspectives

Further topics will be addressed at the upcoming sessions of the WG.

  • Preparing our own “white paper” but first consolidating knowledge on CE
  • Preparing texts supporting RTD initiatives, especially trying to include sediments topics in incoming Horizon, ERDF and Life call texts
  • Preparing texts conveying the message to policymakers: Valorisation should be facilitated by regulations

The next WG-meeting will be held at a place where beneficial uses of sediment are implemented (works, plant) or tested at the pilot scale. Preliminary date/venue: 23-24 October 2019, Bremen, Germany, with a site visit to Delfzijl, NL  (Kleirijperij, see https://www.ecoshape.org/en/projects/clay-ripening-pilot-project/).

This meeting will have 3 separate subsessions to facilitate working on selected topics, and a shared wrap up. A list of possible topics will be circulated to the WG-members with the extended minutes. Participants are kindly requested to select their preference(s). Further topics can be proposed for WG4, planned for early 2020.

If you are interested in joining this WG, please send an email to the SedNet Secretariat and we will add you to the WG-mailing list.


3rd Session SedNet Working Group Sediment Quantity

SedNet WG Sediment Quantity had its 3rd meeting prior to the conference in Dubrovnik.
Progress was made on the production of several WG-documents and further actions were discussed.
If you wish to get involved in the WG, and would like to receive the minutes of the meeting, please contact the SedNet Secretariat.

In the Joint Session of WG Sediment Quantity and WG Sediments in Circular Economy at the end of the afternoon, it was concluded that there is a certain overlap between the subjects of sediment continuum and circular economy. For instance, dredging can be (part of) a measure to influence the sediment budget and continuum, but beneficial re-use of dredged sediments is certainly a circular economic action.

After presentations about the activities of both WGs there was room for discussion. An interesting point of discussion was the use of the idea of sustainability. From a sediment quantity viewpoint, sustainability addresses the restoration of sediment fluxes in order to keep the system as it is or restore former conditions. From a dredging point of view, sustainability pertains to minimizing impacts, coasts, etc. Someone suggested that using the phrase ‘beneficial use of sediment’ might prevent misunderstanding.


New SedNet WG on Sediment Management Concepts & Education-Science-Policy Interfacing

One of the conclusions from the SedNet Conference Session “Sediment Management Concept and Sediment Policy” is that there is a need to share experiences in this field and to develop a SMC Guidance Document. SedNet would like to facilitate this process and has the intention to start a thematic Working Group. Kick-off meeting will be on Wednesday 20 November, starting around noon, ending 21 November around noon. Venue: IETcc-CSIC in Madrid, Spain. If you are interested in getting involved, please contact the SedNet Secretariat.

Beneficial use of dredged sediments in road engineering

This Methodological Guide presents how dredged sediments can be beneficially used in road engineering with a view to sustainable development and to the protection of the environment and of populations. This is the result of research carried out by the Department of Civil and Environmental Engineering (DGCE) at the School of Mines of Douai for more than ten years on the theme of using dredged sediments. It is coherent with French regulations and the methodological framework (ADEME, 2010; SETRA, 2011) that prevailed at the time of the work. The proposed methodology was developed by the Ecole des Mines de Douai as part of France’s SEDIMATERIAUX project and may be reviewed in the light of feedback received at the French national or European level.

SedNet promotes since 2004 beneficial uses of dredged sediments, in a perspective of sustainable development and of circular economy. Road engineering is one of these beneficial uses, as it reduces both waste and mineral extraction.

This guide is not intended for use of sediments abstracted from a river system. It is only intended for harbour and canal dredgings, where restitution to river systems is usually not possible – at least economically.

Otherwise, it should be first considered to reintroduce them where the river system may need them, before considering any engineering use.

Sediment management guidance in support of the WFD

Preceding the 11th SedNet conference, on Monday 1 and Tuesday 2 April SedNet co-organized in Dubrovnik a sediment management workshop for and with the WFD CIS (Common Implementation Strategy) working group ECOSTAT (Ecological status). There were 45 participants from 16 European states and from Turkey. Outcome of the workshop was that the participants unanimously agreed to develop guidance on how sediment management can help to achieve the WFD as well as how this links to other EU policies (MSFD, MSPD, FD, CAP and Nature, Energy and Transport policies): sediment management is an issue that cross-cuts through all these policies, while the WFD (and MSFD and FD) is the core-policy. ECOSTAT takes the lead in developing the guidance and asked SedNet and national experts to bring in their expertise and experience.

Another ECOSTAT workshop conclusion was that sediment management is complex and thus we need to significantly invest in a better understanding of this complexity to be able to better inform river-sea managers and policy makers.

The report of the workshop is in prep., but the agenda and presentations are already publicly available at CIRCA website.

Emerging Contaminants

OVAM, the Public Waste Agency of Flanders, wishes to initiate an international multi-stakeholder network on Emerging Contaminants in Soil (EmConSoil), and more specific on the policy challenges of this theme.

The first focus of this network is on soil, but of course there is a very close relation with sediments. F.i. PFAS/PFOA is found in soils and sediments, and we need regulations to prevent that sediments, contaminated with PFAS/PFOA are reused as soil.

We all have to deal with the legacy of emerging contaminants, and as OVAM we really feel the urgent need for concerted actions and initiatives. It is clear that the problem cannot be solved by the regulatory authorities alone. In this network, OVAM aims to bring together policy makers, scientists, consultancies and problem owners.

EmConSoil will be an open network for all stakeholders from different sectors and countries. The aims are to exchange knowledge, to develop strategies and policies through co-creation, to raise awareness, and intensify collaboration between all stakeholders. This will be done by information sharing through a website, conferences, workshops, etc.

EmConSoil will work in close collaboration with other networks, like SedNet.

Microplastics in sediments

GESAMP (the UN inter-agency body ‘the Group of Experts in the Scientific Aspects of Marine Environmental Protection’ – www.gesamp.org) produced a couple of reports about microplastics in sediments:

  1. Sources, fate and effects of microplastics in the marine environment (Part 1)
  2. Sources, fate and effects of microplastics in the marine environment (Part 2)
  3. Guidelines for the monitoring and assessment of plastic litter in the oceans 

Besides covering the design of monitoring and assessment programmes, monitoring methods for shorelines, the sea surface, water column, seafloor and marine biota, the latter report includes recommendations for:

  • Definitions/terminology
  • sampling methods
  • sampling processing
  • physico-chemical characterization
  • analysis of chemicals associated with microplastics
  • biological characterization

Dramatic decrease of sediment in
Danube and Rhine

Dramatic sediment deficits have already been reported for e.g. the Mekong, Yellow River, Yangtze and Mississippi and their delta’s and coastal seas. However, very recent findings for the Danube and Rhine rivers show also dramatic figures for Europe:  60% reduction of suspended sediment input by the Danube to the Black Sea (Habersack, 2019) and 70% reduction of the suspended sediment load of the Rhine at is entry point in the Netherlands since 1952 (van der Perk et al., 2019). These figures (so for Rhine and Danube) only relate to suspended sediment, figures for bedload (gravel, sand, pebbles) are not yet readily available/insights/data are still hugely lacking. What are the impacts? We need to significantly advance the state-of-the-art in our integrated and holistic understanding of the societal, economic as well as ecological impacts resulting from a deficit of sediments in oceans, seas, coastal and inland waters. Hopefully Horizon Europe will provide a great opportunity for advancing of this understanding. Based on that understanding sustainable (nature-based) solutions can be proposed to restore and protect the flow of sediments from inland waters to seas and oceans in Europe as well as globally.



Implementing Measures for Sustainable Estuaries

IMMERSE, or “Implementing Measures for Sustainable Estuaries,” aims to accelerate the implementation of large-scale measures that address multiple estuary management challenges, while increasing their cost-efficiency and enhancing stakeholder commitment. More information is available on the project website.

In order to advance development and transfer of solutions across estuaries in the North Sea Region, IMMERSE is organizing its first Transnational Exchange Lab on 12 – 13 June, 2019 in Gothenburg, Sweden. The interactive workshop is designed to support the project’s objective of improving the quality of estuary management measures by drawing from transnational knowledge and experiences. The 1st Transnational Exchange Lab will focus on sediment management, including innovative treatment methods of contaminated sediments from the Port of Gothenburg, flood protection and governance issues. Please see the draft programme here. 

At the Exchange Lab, IMMERSE partners, North Sea Region estuary managers and relevant stakeholders will explore solutions and share experiences through a variety of discussion formats. We invite SedNet members to join us at the Exchange Lab to share your experiences and expertise.

More information, including registration and travel information, is available on the event page.

Sediments in WFD Reporting 2016

Sediments are an integral part of the ecosystem and can have an impact on both ecological and chemical status of surface water bodies.  Despite the sediment management is not addressed in the Water Framework Directive (WFD) as a specific issue, the Directive refers to a need of environmental quality standards for priority substances in sediments and to the necessity of undisturbed sediment transport for achieving high status of surface water bodies. In general, quality and quantity of sediments play a significant role in achieving WFD environmental objectives and, therefore, reporting on various aspects of sediment management has to be included in a river basin management plan.

WFD Reporting Guidance 2016 provides EU Member States with guidance on how the various aspects of the Water Framework Directive (WFD) should be reported to the European Commission. The following text provides a brief overview of reporting requirements on sediments as described in the WFD Reporting Guidance 2016.

Role of sediments in the assessment of the chemical and ecological status

Reporting of the second River Basin Management Plans (RBMPs) in 2016 brings a new element into play due to legislation which was not fully in force at the time the first RBMPs were adopted. The Environmental Quality Standards Directive 2008/105/EC (EQS Directive), as adopted in 2008, will be fully in force for the second RBMPs. Some Member States did not implement the Directive in the first RBMPs given the fact that transposition deadline was in July 2010, after the adoption of the RBMPs. A number of elements of the EQS Directive which were not reported in 2010 are relevant for the second RBMPs and these include trend monitoring in sediment and/or biota of Priority Substances.

‘Good surface water chemical status’ means the chemical status required to meet the Environmental Objectives for surface waters established in Article 4(1)(a) of the WFD, that is the chemical status achieved by a body of surface water in which concentrations of pollutants do not exceed the environmental quality standards (EQS). Decision 2455/2001/EC of the European Parliament and of the Council of 20 November 2001 established the list of Priority Substances in the field of water policy. The Decision identified the substances for which EQS were to be set at Community level which was implemented by means of Directive 2008/105/EC (the EQS Directive (EQSD)). Eight other pollutants that were regulated by Directive 76/464/EEC were also incorporated into the assessment of chemical status. The EQSD includes a number of other obligations relating to Priority Substances, among which is the trend monitoring of certain Priority Substances in sediment or biota (Article 3(3) EQSD).

Directive 2013/39/EU, amending the WFD and EQSD as regards Priority Substances, was adopted on 12 August 2013. The revised EQSs for existing Priority Substances should be taken into account for the first time in RBMPs covering the period 2015 to 2021. The newly identified Priority Substances and their EQSs should be taken into account in the establishment of supplementary monitoring programmes and in preliminary Programmes of Measures to be reported by Member States by the end of 2018. With the aim of achieving good surface water chemical status, the revised EQSs for existing Priority Substances should be met by the end of 2021 and the EQSs for newly identified Priority Substances by the end of 2027.

WFD Reporting Guidance 2016 asks the Member States to report the matrix in which each chemical substance is monitored and this includes sediment, suspended sediment and settled sediment. Moreover, the RBMPs or background documents should include information about how are Priority Substances monitored in sediments and/or biota to assess long-term trends of Priority Substances. Article 3.3 of Directive 2008/105/EC (Article 3.6 in the current version as amended by Directive 2013/39/EU) states that ‘Member States shall determine the frequency of monitoring in sediment and/or biota so as to provide sufficient data for a reliable long-term trend analysis. As a guideline, monitoring should take place every three years, unless technical knowledge and expert judgment justify another interval.’  WFD Reporting Guidance 2016 also asks that if arrangements are in place for the long-term trend analysis of concentrations of those Priority Substances listed in Part A of Annex I of the EQS Directive 2008/105/EC that tend to accumulate in sediment and/or biota (Article 3(3) EQSD), references or hyperlinks to technical documents must be provided by Member State where further specific information can be found.

In addition to Priority Substances also River Basin Specific Pollutants have to be monitored in surface water bodies. In case a River Basin Specific Pollutant exceeds its good-moderate EQS it would cause a failure to achieve good ecological status/potential in the respective surface water body. Similarly as for Priority Substances also for the  River Basin Specific Pollutants the WFD Reporting Guidance 2016 asks if these substances are monitored in sediment, suspended sediment and settled sediment.

Focus on sediments in WFD Programme of Measures

The WFD requires that, within each RBD, a Programme of Measures (PoM) is established to address the significant issues identified and to allow the achievement of the WFD environmental objectives. The Directive further specifies that the PoM shall include as a minimum ‘basic measures’ and, where necessary to achieve objectives, ‘supplementary measures’. Basic measures among others  comprise measures to prevent or control inputs of diffuse pollutants. These measures include also controls or binding requirements at farm level to address soil erosion and pollution of water bodies with sediment (Article 11 (3h)).

The concept of Key Types of Measures (KTMs) was developed in 2012 to simplify reporting. KTMs are groups of measures identified by Member States in the PoMs which target the same pressure or purpose. The 25 predefined KTMs include two measures addressing sediments: KTM4 Remediation of contaminated sites (historical pollution including sediments, groundwater, soil) and KTM17 Measures to reduce sediment from soil erosion and surface run-off. The member States are obliged to report on application of these sediment-related KTMs.

Sediment management in International RBMPs

The WFD requires co-ordination of the Programmes of Measures in transboundary River Basin Districts and the European Commission will assess whether sufficient co-ordination has taken place in transboundary RBDs. WFD Reporting Guidance 2016 asks if the international RBMP address sediment management.

CEAMaS final conference 2015

The final conference of the project North-Western Interreg IVB CEAMaS took place on 17 September 2015 in Brussels at BBRI Buildings. This conference was organized by the cd2e (leader of the project) and the 7 partners of the 4 countries having taken part in this project. More than 60 experts and stakeholders concerned by harbor’s dredged sediment management attended this event during which shared outcomes and results on the technical, social, economic and global environmental impact issues were presented. The results obtained through the 5 work packages of the project have made it possible to have a transnational vision on the reuse of harbor’s dredged sediment in civil engineering applications. Tools and studies developed during the project are available on the CEAMaS website. How to continue to share? how to continue innovative approaches? The answer to these questions were given by the perspective to develop a European resource center for circular economy with sediment reuse. This initiative was shared by the majority of the partners and led to the signature of common understanding agreement.

Sediment National Days

The resource center SEDILAB by cd2e organized on 19 and 20 November 2015 for the first time outside the French Nord-Pas-de-Calais region the Sediment National Days (SND). This event was organized in partnership with GEODE (group study and observation on dredging and environment) and BRGM in Brittany (Nantes) and has succeeded to bring together actors (more than a hundred participants) involved and interested in dredged sediment issues in the Atlantic seaboard. The purpose of the opening towards another region is to share the experiment of the Nord-Pas-de-Calais Area concerning the reuse of dredged sediment and to duplicate at the national scale the “Sédimatériaux” approach. An experiment which relates to the methodologies and results achieved through the national approach “Sédimatériaux” and the Interreg projects such as CEAMaS, PRISMA and GetSed…Two subjects were discussed during these days:  responsible practices for on the ground sediment reuse and the dumping of the dredged sediment in marine and estuarien environment during the GEODE forum.

Workshop on the reuse of (contaminated) sediments

During the SedNet conference in Krakow (23-26 September 2015) a workshop was organised on the Reuse of (Contaminated) Sediments. The platform was to share each other’s experiences with sediment reuse projects in Europe and the USA. Therefore most of the time was given to the floor to present projects, and how they came to pass. The results can be found at: https://sednet.org/events/sednet-conference-2015/sednet-conference-2015-presentations (10. Workshop on the Reuse of (Contaminated) Sediments). The unified premise was to get behind the notion that sediments should be viewed as a resource and not a waste, and find solutions with other waste streams in which sediments are part of the solution.

As an example, the Lift up of Lowlands project evaluated the potential of using dredged sediments to reverse the process of land subsidence in polder areas. For that, lab-, meso- and field-scale experiments were performed and it was concluded that most subsidence of organic dredged sediments was due to shrinkage and not organic matter mineralization.

Another example of a new application which was implemented after the SedNet meeting in Krakow is the design of a steel slag dike to prevent slope instability on a sediment storage site.

Photo article A. Wijdeveld - Newsletter May 2016

Photo: Slope instability at a sand quarry

Figure Article A. Wijdeveld - Newsletter May 2016
Figure: Impression of a redesign of the sediment storage site, using a steel slag dike (in blue) to prevent slope instability.  

The sediment needs to be kept in place, but also the sediment prevents leaching of metals from the steel slag dike towards the ground- and surface water. A series of tests were carried out to look at the chemical and physical behavior of both the steel slags and sediments when building a dike with a height of almost 10 meters on top of a sediment layer, on a slope of 1:4.

The feasibility evaluation gave a positive outcome; the construction of the dike is possible if done carefully and taking into account a limited downward slip. The design and construction of the dike has been put on the market in April 2016, using the knowledge gained from the tests and model calculations.

A second example was less successful. In February there was a call for an EU program called BONUS. The objective was meeting the multifaceted challenges in linking the Baltic Sea with its coast and catchment, and specifically using Eco-technological approaches to achieve good ecological status in the Baltic Sea. We drafted a proposal with four of the companies present during the SedNet workshop and invited additional partners from the Baltic Sea region. Regrettably, the co-founding of the proposal could not be arranged within the deadline of the call.

The latest opportunity we see is the new INTERREG call for the region North-West Europe (NWE), opening the 18th of April 2016 and closing the 27th of May 20216. The INTERREG perspective focuses on stakeholder involvement and participation. The CEAMaS project ended with a well-equipped toolbox but with a limited pathway to implement this toolbox. The new proposal focuses on using the toolbox within projects and pilots already going on with regard to sediment reuse. An important part of the proposal is also the concept of looking at sediments from a circular economy perspective. This includes the option of using sediments as a solution to facilitate the reuse of other secondary resources, as was the case for the steel slag dike.

While not all participants of the workshop are involved in these three initiatives, there are many more opportunities to look at sediment as a resource.  Please send your examples to Sednet (Marjan.Euser@deltares.nl)  and  we hope to be able to organize a new workshop with more examples during the next Sednet conference in 2017.

Abiotic flows (such as sediment related) should be inherent part of ecosystem services classification

A paper on abiotic flows has been published last month (April 2016) in the journal Ecosystem Services.


  • Abiotic flows are neglected or addressed inconsistently in ecosystem services (ES) classifications.
  • Theoretical and practical arguments are provided to include them.
  • This supports consistency and optimizes the integration power of the ES concept.

The paper also presents three cases to illustrate the importance to society of abiotic flows and their management. The examples demonstrate that especially sediment resources and dynamics play a key role in the provision of abiotic flows of ecosystems.

The article is free accessible online until May 24, 2016: http://authors.elsevier.com/a/1Spph7szSIn9gR

INSPIRATION – developing a Strategic Research Agenda

INSPIRATION is a coordination and support action funded by the European Commission in order to develop a Strategic Research Agenda (SRA) for Europe on soil, land use and land management.

Funded by the European Horizon2020 programme, INSPIRATION aims at establishing a funder and end-user demand-driven Strategic Research Agenda (SRA) for land use, land-use changes and soil management in Europe. With more than 20 partners from 17 countries, its objectives are to (1) formulate, consult on and revise an end-user oriented SRA; (2) scope out models of implementing this SRA; and (3) prepare a network of public and private funding institutions willing to commonly fund the execution of the SRA. The mission of the project is to improve the supply and effectiveness of science/knowledge take-up by those who really need it in order to address national and European societal challenges related to land management and the soil, sediment, water system. In this endeavour. For that a systematic bottom-up and stakeholder engagement approach is applied. Learn more about INSPIRATION:


CEDA series of webinars on Dredging Technology

CEDA is running a series of webinars on dredging technology this year – with a focus on the Cutter Suction Dredge and the Trailing Suction Hopper Dredge.

The series will offer delegates training, at two different levels, depending on their working knowledge and experience. Foundation level webinars will provide a sound basis on topics for professionals working in the dredging field, who don’t have the basic grounding in the subject, and who may have only a limited experience working with dredging equipment and technology. The practitioner level webinars will serve the more experienced engineers who have been through formal training in the field and have experience with dredging equipment and technology. These  events will provide in-depth knowledge on specific aspects of each topic.

The webinars are free and are open to everyone i.e. also to non- members of CEDA.

More info on: CEDA webinars


CEDA questionnaire on turbidity limits

Increasing environmental scrutiny for dredging projects has introduced threshold limits for turbidity generating activities (incl. dredging and dredged sediment placement). The setup, basis, monitoring and management of ‘turbidity limits’ is widespread, but very disperse.

Therefore, the CEDA Environment Commission (CEC) developed a questionnaire to record, inform guidance and best practice in setting and working with turbidity limits.

CEDA members and other stakeholders, whether regulator, project owner, contractor, or consultant, are invited to complete the questionnaire and give an insight to the challenges faced around turbidity limits. Your responses will be used to develop an information paper which all respondents will have access to. The questionnaire consists of four parts: • Part 1 – establishes project type and conditions • Part 2 – investigates how turbidity limits were set for the project • Part 3 – deals with monitoring effort and set up for the project • Part 4 – covers responses and excedance procedures/efforts You can fill in the questionnaire online by clicking the link http://goo.gl/forms/UaeHBF9cfK or download the hard copy here and send the completed and scanned pages to csiti@dredging.org

Please only cover one project per questionnaire when responding.

The project information will be treated confidential and will only be used in a statistical manner for the information paper without disclosure of the source.

Should you have any questions or comments, please contact the CEDA Secretariat: ceda@dredging.org

New chairman SedNet

Axel Netzband (left) and Marc Eisma

Since 2005 Axel Netzband of the Hamburg Port Authority has been chairman of SedNet.
Early 2012 Axel decided to withdraw as chairman in order to give room to a new candidate. At the Steering Group meeting in September 2012 Marc Eisma of the Port of Rotterdam Authority was elected as Axel’s successor. Also a vice-chair was elected: Christophe Mouvet of BRGM, France.

At the Steering Group meeting Axel was thanked for the excellent work he has done all these years for SedNet. Axel received a “Best SedNet Chairman Award” from the Steering Group.
Axel will stay on as regular Steering Group member.

The Steering Group congratulated Marc Eisma and Christophe Mouvet in their new role and wished them success with the management of our network.

Sediment management course highly valued in the Sava river basin

The “practical training course on sustainable sediment management with the Sava river basin as showcase” was held 15-18 October 2012 in Zagreb, Croatia. It was organized in close cooperation by the International Sava River Basin Commission (ISRBC), UNESCO Venice Office, UNESCO IHP International Sediment Initiative (ISI) and SedNet. The participants valuated the course in general as ‘very good’. They gave the same rate for the aspect ‘usefulness’.

The course (photo: Samo Grošelj)

A nice summary remark of one of the participants: “It really is and will be a “showcase” for other international planning. The planning will certainly make the case for the importance of understanding the dynamics and functions of sediments.”

This was the first part of the course. This part focused on how to achieve a sediment balance and on monitoring and assessment of the quantity and quality of sediments in the Sava.

Eroding Sava riverbanks: one of the sediment management issues (photo: Jos Brils

Top experts from Europe and the United States of America addressed the theory on these topics. The national experts from the four Sava countries – Slovenia, Croatia, Bosnia & Herzegovina and Serbia – subsequently presented the status of their own countries for these topics. Thereafter, the course participants were assisted by a professional moderator in connecting ‘theory’ to ‘practice’. The course participants were twenty local experts (policy makers, agencies and scientists) from the Sava river basin. It is the intention that they will get involved in the drafting of the sustainable sediment management plan for the Sava river basin. The four Sava countries committed themselves to get to such a plan.

The main outcomes of the course:
The participants – for several of them it was the first time they met – now share a common understanding on the key sediment management issues for the Sava;
These issues are: too much, too little or too dirty sediment, now or in the future. This is, or can be, caused by further improvement of the navigability of the Sava, soil erosion, pollution (agriculture and industrial) and existing and planned dams;
Based on a thorough brainstorming during the practical part of the course, the participants are expected to achieve the final course objectives by drafting the guidance and the implementation programme for the development of the Sava sediment management plan, as well as identifying the projects needed to develop different modules of the Sava sediment management plan;
The secretariat of the ISRBC will propose to the Commissioners to endorse the formation of an ISRBC expert group to deal with sediment management. That group will then guide the further drafting of the sediment management plan.

We are now even more motivated to prepare part 2 of the course, in which we will address measures and governance aspects. Once we succeeded in securing the funds for part 2 of the course, and also successful conclusion of that part, it is the intention of UNESCO to promote and offer the course globally and thus to contribute to a more sustainable management of sediment in any river basin that is willing to face this challenge.

Part 1 of the course was made possible by the in kind cooperation and/or sponsorship of several institutions that we greatly want to acknowledge: UNESCO Venice Office, UNESCO Germany IHP National committee, UNESCO IHP ISI, ISRBC, BRGM, HAW, VMM, Deltares and SedNet. All presentations given during the course are available at the ISRBC website (http://www.savacommission.org/event_detail/8/22/273) as well as at the SedNet and ISI websites.

SedNet short course at COASTEXPO 2012

On September 20, 2012 SedNet organised, following the invitation of the Scientific Committee, a Short Course on Sediment Management at COASTEXPO 2012. COASTEXPO is a Conference and Exhibition held annually in Ferrara (Italy), focused on Coastal Zone Management issues. Title of the course was: “Lessons learned from success Case Studies of sediment management in Europe”. The course was organised and coordinated by Andrea Barbanti, member of SedNet SG, while the 2 case studies were presented by Bruno Lemiere – BRGM (Inland waterways sediment management in Northern France and Walloon Belgium) and Jos Brils – Deltares / SedNet SG (Sustainable sediment management in the Scheldt-Meuse-Rhine delta).

Aim of the course was to give the opportunity to sediment-related problem owners (or expected problem solvers) to get in contact with significant and state-of-the-art experiences on sediment management and share best practices. The interactive (and informal) format of the course offered the opportunity to the participants: i) to explore in details the ingredients of a success Case Study (not only a matter of technicalities); ii) to reflect in the Case Studies their own experiences and open issues; iii) to interact and share experiences with other participants.

Topics addressed have been:
Technical and scientific aspects (site assessment, parameters and quality standards, decision frameworks, systemic approach, conditions for reuse/disposal, treatment types, tools, monitoring, sustainability analysis,…)
Legislation and protocols: principles and main practical consequences / practices
Administrative: institutional framework, decision making, procedures, permits
Economics: costs of measures, financing, incentives, private-public initiatives.

About 30 people – mostly from Italy – with different backgrounds and interests (Central/Local Administrations, Port Authorities, Environmental Agencies, Universities and Research, Operators and Consultants) attended the course. The course was highly appreciated by the attendants and they participated lively in the discussions.
Presentations are available at the Conference website.

SedNet Symposium “Understanding sediment processes at catchment scale”, Koblenz, Germany, June 2013

SedNet is organising a one day symposium at the 6th IAHS International Conference on Water Resources and Environmental Research: Water and Environmental Dynamics , which will run from 3-7 June 2013 in Koblenz, Germany. The SedNet symposium is on Understanding sediment processes at catchment scale and is convened by Peter Heininger (Federal Institute of Hydrology, Germany), Sue White (Cranfield, UK) and Ivana Teodorovich (University of Novi Sad, Serbia).

Session abstract: Sediment as an essential condition for the hydrological, geomorphological and ecological functioning of river basins, as a pollutant in its own right, and as a vector for other associated contaminants, crosses many traditional management sectors, and is subject to many sets of legislation or regulation. There are often multiple sources of sediment affecting multiple management objectives in locations throughout river basins, and the transfer pathways between source and impact are often long and complex. Mobilisation and movement of sediment is often associated with high energy, high flow events, and few monitoring programmes adequately address this part of the flow range. Climate change predictions are for such events to become both larger and more frequent, and the resultant shift in flow distributions will mean that rivers will remobilise, releasing both sediment and legacy contaminants from floodplains and river banks and bed. Changing physical and chemical conditions may also mean that sediment-bound contaminants will behave differently in future.

Meanwhile, the European Water Framework Directive (WFD) requires us to manage our water environment at catchment scale. This is perhaps more complex for sediment than for other contaminants because of the episodic nature of sediment transfer, long storage times within the system and the wide range of associated contaminants. However, for many river basins in Europe sediment and/or associated contaminants form one of the major barriers to meeting WFD requirements. Therefore there is an urgent need to develop approaches based on process understanding for sediment management at catchment scale.

This session will welcome papers on catchment scale management approaches, improved process understanding and implications of a changing environment on sediment management at the river basin scale.

December 16th is the deadline for abstracts – so please start planning your paper now! Further details about the conference can be found at:

Estuarine Coastal Sciences Association hosted special session at SedNet 2013 Portugal “Changing Hydrodynamics of Estuaries and Tidal River Systems”

The Estuarine and Coastal Sciences Association, ECSA, will be hosting a special session at next year’s SedNet conference in Portugal. The session will be presented by 3 keynote speakers from ECSA with expertise in estuarine hydrodynamics, contaminant processes and ecology. They will outline current knowledge and tools for understanding and predicting changing hydrodynamics in estuarine systems and explore the implications this may have for the fate of contaminants and nutrients and the ecological status of estuaries. The presentations will be followed by a discussion of the gaps in scientific and technical knowledge and the short- to medium-term consequences for management.

The presentations will focus on the interactions between tidal and fluvial hydrodynamics in estuarine and tidal freshwater rivers and their influence on chemical and biological processes over various timescales. The speakers will explore the responses to, and consequences of, human interventions, such as tidal barrages, weirs, restoration and flood management/storage schemes, and to predicted changes in the frequency and magnitude of coastal storm surges, river discharge and sea level rise. Natural and human-induced changes to estuarine hydrodynamics and geomorphology will affect the transport of sediment (mud, silt and sand), including the redistribution of contaminated bed sediment. Similarly, the transport of suspended sediment from catchment to coast is fundamental to the ability of estuaries to ‘filter’ contaminants, consequently any modification of physicochemical gradients occurring across the saltwater:freshwater interface will influence the fate of contaminants. All these factors may have wide ranging implications for water and sediment quality, biogeochemical cycling (e.g nutrients and contaminants), and ultimately the ecological status of estuaries and their tidal reaches.

The Estuarine and Coastal Sciences Association is an international organization dedicated to the promotion and advancement of multidisciplinary research into all aspects of estuaries and coasts, and the application of science and technology for their sustainable environmental management. ECSA’s activities, interests and membership extend throughout Europe and to many other regions around the world. The Association has been involved in the organization of nearly 50 conferences to date, with future events planned for China, SE Asia and Brazil. The Association also supports local meetings concerning regional estuaries or coastal areas, and arranges scientific workshops. ECSA has an associated international journal Estuarine and Coastal Shelf Science and also supports the production of a variety of other scientific publications including a Bulletin for members, with two issues each year.

9th Flemish Water forum: ‘Sediment, the hidden link in water policy’

The Coordination Commission Integrated Water Management in Flanders organized their 9th water forum on June 1st, 2012. The central theme of this forum was sediment as the hidden link in water policy, to emphasize the added value of a joined and integrated sediment management. The forum was opened by Jos Brils who presented the vision of SedNet regarding the need to change sediment management from a waste oriented perspective into an integrated management approach on a basin scale tackling the challenges we are facing today and tomorrow with regard to integrated water management. Subsequently six themes were addressed namely: ‘reduction of sediment inflow’, ‘ room for sediment’, ‘ creative and efficient dredging’, ‘monitoring and modeling’, ‘solving the problem of contaminated sediments’ and ‘treatment and reuse of sediments’. The scope of each theme as part of the hidden link within integrated water policy and management was presented followed by some examples from the field.
170 people, representing policy makers, water managers, research institutes, universities, consultancies and ngo’s attended the forum. There was a general consensus that the development of a good sediment balance, an improved understanding of the link between sediment, water quality and ecosystem services, and good communication with regard to these issues is essential to get support for taking measures to enhance sustainable sediment management and to improve the status of our water bodies. All stakeholders confirmed to focus also on sustainable sediment management when making up the second generation of river basin management plans. Finally everyone showed also engagement to work on a positive perspective for sediment related issues in Flanders.

Blueprint to safeguard EU-waters has been approved

TheCommission has launched a Blueprint to Safeguard Europe’s Water Resources, a strategy for ensuring that enough good quality water is available to meet the needs of people, the economy and the environment.
EU waters are not doing well in terms of quality, despite improvements in recent years. Water quantity is of equal concern with water scarcity spreading in Europe and extreme events (like floods) increasing in too many Member States.
We must step up our efforts in order to deal with old and emerging challenges, including water pollution, water abstraction for agriculture and energy production, land use and the impacts of climate change. Strengthened measures are needed to help the EU protect its water resources and become more resource (including water) efficient.
Environment Commissioner Janez Potočnik said: “This Blueprint shows we have a good understanding of the problems we face and a solid platform to tackle them. The time has come to take action to deliver the full benefits of our legislation and create opportunities for innovative solutions in water policy and the water industry. What is needed is a sustainable balance between water demand and supply, taking into account the needs of both people and the natural ecosystems they depend on.”

The Blueprint can be downloaded here. Pressrelease you can find here.

Commission Presents New Guidelines for Inland Navigation and Natura 2000, with relation to maintenance dredging

Session On 18 October the European Commission published new guidelineson inland navigation and nature protection to assist the sector in applying EU environmental legislation.

The guidelines emphasize the development of inland waterway transport infrastructure as well as the conservation of rivers from the perspective of protecting Europe’s rare species and habitats under the EU Birds and Habitats Directives and in the wider context of the Water Framework Directive.
The Commission guidelines provide guidance on how best to ensure that activities related to the development and management of inland waterways are compatible with EU environmental policy in general and nature legislation in particular. The document focuses on the construction, maintenance and upgrading of infrastructure projects related to commercial inland waterway transport. It was written in consultation with members of the European Commission Working Group on Rivers which has provided valuable feedback on the various drafts of the guidance document.
Particular attention is given to explaining how to develop integrated projects which aim to take account of the river’s ecological processes early on in the design process and which search for win-win solutions for both inland waterway transport and biodiversity wherever possible. This guidance document also outlines the procedures to follow when carrying out an appropriate assessment under Article 6 of the Habitats Directive. In that respect, specific reference is made to capital and maintenance dredging works. In the guidelines, the Commission confirms that maintenance dredging works normally only maintain a certain state of infrastructure and do not qualify as a project in the sense of Article 6(3) of the Habitats Directive. Maintenance operations may only be regarded as constituting distinct projects in cases of changing techniques, conditions or regularity under which they are carried out.
The document complements previously published “guidelines on developments in ports and estuaries”, which were published in 2011.

Portuguese Marine Strategy addresses sediment contamination

The Marine Strategy Framework Directive (MSFD), adopted in 2008, establishes a framework within Member States shall take the necessary measures to achieve or maintain good environmental status in the marine environment. The first major reports by Member States to the Commission are due in 2012, covering an initial assessment of marine waters, the determination of good environmental status and the setting of environmental targets. The draft version of the Portuguese report was made available for public consultation in September. The report concludes that overall the Portuguese marine waters are in good condition, but that there is still room for improvement. With regard to Descriptor 8, the concentrations of contaminants are at levels not giving rise to pollution effects in all but one area – the continental shelf close to the Tagus and Sado estuaries. In this area, under greater influence of important cities, ports and industries, the ‘good environmental status’ target was considered not reached due to sediment contamination by hazardous substances. However, the report recognizes that the situation mainly results from historic contamination. Metal concentrations in marine fish species have been observed to decrease in the same area over the last decade (Mar Pollut Bull 62:2854-2858), which is encouraging with regard to the long-term improvement of marine sediment quality.

ARCH: Architecture and roadmap to manage multiple pressures on lagoons

ARCH is a four-year collaborative research project funded by the Seventh Framework Programme for research and technological development (FP7) of the European Commission. Thematically the project belongs to Cooperation Theme 6 Environment (including climate change). The project team is composed of 11 institutions from 9 European countries and coordinated by the Norwegian Geotechnical Institute (NGI). Through experimentation with and development of innovative knowledge brokering instruments, ARCH aims to develop participative methodologies in collaboration with the involved managers, policy makers and stakeholders to manage the multiple problems affecting lagoons in Europe.

State-of-the-Lagoon reports
The task of the ARCH is elaboration of ‘integrated lagoon management plans’ for selected case studies. To understand the complexity of the lagoon regions “state-of-the-lagoon” reports have been prepared for the 10 case study sites. They enlarge our knowledge and provide basis for discussions with the stakeholders. The reports show the dynamic functioning of each lagoon region. They also highlight how the lagoon communities manage and cope with adverse negative effects so important nowadays, i.e. they analyse evolutionary resilience of the lagoon regions in a long run.

Stake holder involvement
The lagoon regions are described as a system composed of two interrelated parts: the “natural system” and the “human” system (composed of the socio-economic and the governance components). It has been decided to make use of both indicators and narratives for description of the main elements of the lagoon regions and respective interactions.

In complex environmental problems, responsibilities, knowledge and power are distributed among the actors involved. Thus stakeholders should be involved, because they are responsible for certain aspects of the environmental problem, they have specific knowledge that should be brought into the process, or because they have a certain power: power to obstruct or power to realize. Stakeholder involvement as a process differs from traditional public consultation procedures in that stakeholders are involved early enough to influence policies when they are formulated. It makes sense, thus, to involve stakeholders in policy problems that are complex, and we should do that from an early stage of the policy process. The next stage of the project will therefore focus on stakeholder involvement through a series of 3 workshops at each case study site.

New Research Projects in the UK

The The UK national Research Councils are funding a number of research studies which include the role of sediment and debris in flooding. Two projects have already been funded by the Engineering and Physical Sciences Research Council and will start in January 2013 and run for 3 years:

Delivering and Evaluating Multiple Flood Risk Benefits in Blue-Green Cities: The aim is to develop new strategies for managing urban flood risk as part of wider, integrated urban planning intended to achieve environmental enhancement and urban renewal in which multiple benefits of creating blue-green cities are rigorously evaluated and understood. One of the objectives is to model existing flood risks using coupled surface/sub-surface hydrodynamic models linked to semi-quantitative assessments of sediment/debris dynamics and habitats, using fieldwork where necessary to fill knowledge gaps in urban drainage network forms and functions
Flood MEMORY: Multi-Event Modelling Of Risk & Recovery: The aim is to study the impacts of clusters of floods in terms of the memory of physical and social systems. The temporal clustering of flood events in time has a critical effect in reducing the ability of systems to recover to pre-flood conditions which can lead to amplified damage in a second flood event. This can be considered as system “memory”, the timeframes of which will be highly variable and range from days to years according to system component. Whilst major floods undoubtedly mobilise channels and large amounts of sediment, repeated small floods play a role in adjusting hillslopes and channels back to an “equilibrium” state. This means that the assumption of similarity in flood risk for similar events is unfounded. The project will consider both fluvial and coastal flooding through source-pathway-receptor models in the fluvial environment and models of beach change for coastal floods.

Further information on sediment aspects of these projects can be obtained from Sue White, sue.white@cranfield.ac.uk

Meanwhile a major funding initiative from the Natural Environment Research Council is focussed on improving our ability to predict and manage impacts of Flooding from Intense Rainfall. A major component of this work will relate to the crossing of process thresholds in sediment and debris supply (hillslope erosion, gullying, landslides, rural and urban debris and changing channel morphology) alongside work on changing conveyance during floods due to the high sediment and debris inputs and blockage at key infrastructure (bridges, culverts, drains). Funding will start in April 2013 and successful bidders will be announced in late 2012.

Long-term suspended sediment data collection

A paper on long-term suspended sediment data collected from over 600 reference-condition (i.e. high ecological status) river sites (42 different ecosystem types) across the temperate climate zone, in order to (1) determine differences in the suspended sediment concentrations that are inhabited by different freshwater ecosystems, and (2) identify, through modelling, the catchment environmental characteristics that influence background concentrations of suspended sediment, was published this summer.

The paper can be found on www.sciencedirect.com

The corresponding author of the research group (Dr G. S. Bilotta, School of Environment and Technology, University of Brighton, UK) reports that they are currently working on the next phase of the model, improving the specificity of predictions and using alternative, more ecologically-meaningful, metrics of suspended sediment exposure (concentration-duration frequency approach).

Review on the International Magdeburger Seminar on River Protection, held on 10-11 October 2012, Hamburg, Germany

The 15th International Magdeburger Seminar on River Protection focused on “The River Elbe and its sediments”. For the first time in the more than 20 years long lasting history of the seminar it took place in Hamburg on the 10th and 11th October 2012. More than 180 experts from the German and Czech part of the Elbe river basin discussed the importance of sediments regarding their key ecological and hydrological requirements. A total of 24 papers and 50 posters with a spatial focus on the mountain and inland areas of the Elbe as well as the Tidal-Elbe and sediment management were presented. Relevant tributary streams of the Elbe such as Vltava, Mulde, Saale and Havel were also focused by the experts. In addition to the seminar three excursions were offered to get in touch with the qualitative and quantitative aspects regarding suspended sediment management of the river Elbe, especially concerning their relevance for the port of Hamburg.
Dr. Pavel Punčochář, president of the International Commission for the Protection of the Elbe River (ICPER) stated “To reach the goals of the European Water Framework Directive it is essential to consequently deal with the contamination issue of sediments”.
Further Dr. Heide Jekel from the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety, Germany added “There is also an intensive discussion on sediment management in Germany within the River Basin Community Elbe (FGG Elbe), the national coordination platform for the German part of the River. Results of the group are used for the development of a national concept as well as an international ICPER-concept.”
Conference material, including presentations given, can be found atwww.ikse-mkol.org

The next International Magdeburger Seminar on River Protection was announced to be arranged in September 2014 at the source of the Elbe in Spindleruv Mlyn, Czech Republic.

Sustainable Management of Contaminated Sediments (SMOCS)

SMOCS – Unlocking port investments through emerging technologies
Demands for a sustainable transport system throughout the world give an ever increasing need to develop ports. Larger ships with deeper draught also add to the need to dredge. In the SMOCS project a guideline, tools and full scale tests have been performed in order to introduce a sustainability approach to managing contaminated sediments and to introduce new emerging technologies. One example of a technology being brought forward by the project is the stabilization/solidification technology that enables contaminated dredged masses to be used as material in port constructions, saving both money and environment thus enabling port investments.

Sustainable management of contaminated sediments, SMOCS

Sustainable dredging for our future…

SMOCS started late 2010 as a joint project comprising several countries around the Baltic Sea. The project is financed by the 10 partners and the Baltic Sea Region Program 2007-2013. A large number of associated and supporting organisations, such as environmental protection agencies, ministries, ports and port organisations provide support also enabling a strong and efficient dissemination of the project key results, findings and deliverables. In late 2012 SMOCS will be finalized and the guideline, tools for assessment and technologies will be released on the SMOCS website www.smocs.eu.

Dredged sediments are a resource as construction material

`Port of Gävle during stabilisation/ solifdification of contaminated sediments

The principle traditional faiths of dredged contaminated sediments are sea or land disposal. The first is not favourable due to environmental concerns in the Baltic Sea Region, the second is very resource demanding and costly. It is in this gap that stabilization and solidification technology has been brought forward and verified in the project, say Professor Sven Knutsson, Luleå University of Technology and Project Manager Göran Holm, Swedish Geotechnical institute. This technology has been used before but is now further developed and used in order to 1) treat the sediments through immobilization of contaminants, 2) improve the engineering properties and 3) enable the treated dredged sediments to be utilized as a construction material in port constructions. Performed sustainability assessments give a clear view on the technology; it decreases the need for natural ending material and has less impact on climate change than traditional handling methods; it is resource and cost effective.

Large investments due in Port of Kokkola, Port of Gävle and Port of Gdynia

TV-broadcast concerning the field test in Port of Gävle

The cost for handling contaminated sediments is very high if done in a traditional manner with disposal them on a landfill says Linda Astner, Environmental Manager at Port of Gävle, Sweden. She continues, – As we were informed of the stabilisation/solidification technology we saw a possibility to save money, environment as well as enable the port to do complementary investments in its facilities. The Port of Gävle has started works in the autumn of 2012 that will treat and use about 600 000 m3 of contaminated sediments for new port areas for e.g. container handling. Soon Port of Kokkola , Finland and Port of Gdynia, Poland as well as others will follow.

SMOCS Network and PortInfra
An additional key output of SMOCS is a network, its heart consists of the ten SMOCS partners who joined the project in 2009, and who now have agreed to interact on the topics of sediments, port construction and to invite other organisations to participate starting 2013. One of the first tasks is to enlarge the network under the thematic umbrella “PortInfra” where the practical needs of ports are matched with best available knowledge.

“River Discharge to the Coastal Ocean: A Global Synthesis”
by John D. Milliman, College of William and Mary, Virginia, USA
Katherine L. Farnsworth, Indiana University of Pennsylvania

Cambridge University Press 2011

Rivers provide the primary link between land and sea, annually discharging about 36 000 km3 of freshwater and more than 20 billion tonnes of solid and dissolved sediments to the global ocean. Utilizing the world’s largest database – 1534 rivers that drain more than 85% of the landmass discharging into the global ocean – this book presents a detailed analysis and synthesis of the processes affecting the fluvial discharge of water, sediment, and dissolved solids to the coastal ocean. The ways in which climatic variation, episodic events, and anthropogenic activities – past, present, and future – affect the quantity and quality of river discharge are discussed in the final two chapters. The book contains 26 tables and more than 165 figures – most in full color – including global and regional maps. The book’s extensive appendix presents the 1534-river database as a series of 44 tables that provide quantitative data regarding the discharge of water, sediment and dissolved solids. The appendix’s 140 maps portray the morphologic, geologic, and climatic character of the watersheds. A complete GIS-based online database.

Soil Erosion Discussion List

SE-LIST (the Soil Erosion Discussion List) has been re-launched this spring. It was started in 1993 as a forum for discussion on any topic related to soil erosion (Bernsdorf and Favis-Mortlock, 1995). The list was originally hosted by the University of Trier, Germany. It then went through several changes before Mark Nearing (USDA-ARS) agreed to run it. During Mark’s term of office, the list was hosted at Purdue University in the USA. It grew to be quite a useful resource.

In 2011, Mark decided to give up running the list, and pass it to someone else; David Favis-Mortlock, senior visiting research associate at the Environmental Change Institute | University of Oxford, agreed to take it on. It has taken a while, but the list is now operational once again. However, it has not been possible to copy the list of subscribers from the Purdue hosting. Thus members of the old SE-LIST will usually need to re-subscribe.

SE-LIST is intended to be a low-volume list, just a few emails per week.
The formal name of SE-LIST is now ouce-soil-erosion@maillist.ox.ac.uk
To post to the list, send an email to ouce-soil-erosion@maillist.ox.ac.uk. Your email will then be sent to all list members. You can only do this if you are subscribed to the list, of course.

To unsubscribe or subscribe, or check who is subscribed, send an email toouce-soil-erosion-help@maillist.ox.ac.uk. You will get an email back with a list of instructions.

If you have any problems posting to the list, you can send an email to ouce-soil-erosion-owner@maillist.ox.ac.uk. Feel free to pass on this announcement to any colleagues who might wish to join SE-LIST.

8th International SedNet conference
Lisbon, Portugal, 6-9 November 2013
Hosted and co-organised by LNEC
“Innovative Sediment Management: How to do more with less”

The preliminary conference program is almost ready and will soon be uploaded on the conference-webpage on www.sednet.org.

The conference program will consist of key-note presentations and parallellecture sessions on
Sediments and ecosystems (and their services)
Integrated sediment management
Sustainable dredged material management
Sediment quality and quantity issues
Interaction between fluvial, estuarine and coastal sediment
Further there are Special Sessions:
ECSA Special Session: Changing hydrodynamics of estuaries and tidal river systems
ARCH Special Session: Management of multiple pressures on estuaries and lagoons in a changing climate
Relationships between sediment and biota in transitional water ecosystems and harbours
Mechanics of sediment transport (see also the “Call for abstracts”, next item of this newsletter)

Working Groups
A new item in the conference program is the starting up of Working Groups.
Thursday 7 November afternoon will provide opportunity for new initiatives – brought forward by the network – on sediment research and management. These Working Group meetings may focus on any topic in the field of sediment research and sediment management. Any conference participant who would like to brainstorm with his fellow-sediment-specialists will be given the possibility to organise such a Working Group meeting. Those meetings are open for any conference participant to join and thus contribute to the discussion. The outcome of these Working Group meetings will be presented briefly in the plenary session at the end of the conference.
The most promising Working Group initiatives may get some support from SedNet to kick-off the execution of activities that they propose.
If you have questions about this initiative or wish to reserve time and a meeting room for a Working Group during the conference, please contact the SedNet Secretariat.

A Working Group that has registered already and will meet on 7 November is:

Working Group: Strengthening the connection between science and policy for improved sediment managementThe Water Framework Directive and Marine Strategy Framework Directive provide opportunities for improved sediment management. Although these opportunities are still not generally seized, both frameworks will probably become the context for sediment management in future. Both directives are characterized by a systemic approach that will ask for integration of scientific knowledge from different disciplines, for stakeholder involvement and appreciation of local knowledge, and for integrated policies (e.g. spatial management) in new governance arrangements instead of sectoral policies that are still mainstream nowadays. The interface between science and policy is extremely important for the development of sediment management within these frameworks as it should provide the evidence base for the interventions and new management opportunities (governance approaches). Instruments for an improved connection between science and policy have been developed in several EU-projects.

A goal of this session is to find out if there is interest in the SedNet-community to start a specific SedNet Working Group on science-policy interfacing for sediments and – if yes – to draft a proposal for that Working Group.

During the conference posters will be exposed. A special Poster Session is held on 6 November at the end of the day.

Conference fee and registration
A registration form can soon be found on www.sednet.org

Call for Abstracts for the Special Session on Mechanics of Sediment Transport
on 7 November 2013
(during the SedNet conference in Lisbon)

Appropriate management of sediments in estuarine and fluvial environments can only be achieved if suitable physically-based theoretical tools are available for end-users. Fundamental research on sediment transport, ranging from grain-scale to intermediate scales, provides adequate closures to modeling large-scale fluvial and estuarine processes. Solutions for problems related to morphological evolution of mobile beds, water quality, restoration works, flood protection measures and ecological equilibrium can thus be given adequate responses.

This Special Session aims at complementally gather researchers working on fundamental issues of sediment transport and researchers and end-users tackling engineering-scaled processes. Prolific discussions, focused on bridging the gaps in engineering knowledge on sediment transport as well as on the experience of modelers in incorporating new theories ensuing from fundamental research in their models, are expected.

Researchers working on mechanics of sediment transport in oceans, rivers or reservoir environments are invited to participate in this special session. Submitted themes may include grain-scale mechanics of sediment transport, river and estuarine morphology, suspended load, cohesive sediments, interaction with turbulence, interaction with structures or ecological considerations. Research relying on experimental methods and instrumentation such as PIV, LDV and acoustic velocimetry as well as numerical work on data production with LES/DNS/SPH and on CFD numerical solutions for engineering-scale problems are especially welcome.

The session is organized by:
Mário J. Franca, École Polytechnique Fédérale de Lausanne, Lausanne, Switzerland
Rui M.L. Ferreira, CEHIDRO, Instituto Superior Técnico – TULisbon, Lisbon, Portugal

Abstract submission
Abstracts shall be submitted directly to the organizers of the session (see contacts below), no later than 1st September 2013.
The template available in SedNet Conference 2013 website should be used.

SedNet Symposium “Understanding sediment processes at catchment scale”, Koblenz, Germany, June 2013

SedNet has organised a one day symposium at the 6th IAHS International Conference on Water Resources and Environmental Research: Water and Environmental Dynamics, which has run from 3-7 June 2013 in Koblenz, Germany. The SedNet symposium was on “Understanding sediment processes at catchment scale” and was convened by Peter Heininger (Federal Institute of Hydrology, Germany), Sue White (Cranfield University, UK), Susanne Heise (HAW Hamburg, Germany), and Ivana Teodorovich (University of Novi Sad, Serbia).

The focus of the 6th conference was set on fostering an integrative understanding of water and the environment, bringing together scientists from the fields of hydrology, environmental research, aquatic ecosystem research, water resources research and management as well as global change to discuss solutions for transient environmental boundary conditions. The SedNet symposium addressed sediment processes at the catchment scale, tackling sediment sources and transfer pathways, monitoring programmes, and sediment management.

Eleven abstracts were selected for presentation at the SedNet symposium, covering a large number of fundamental issues in environmental sciences and hydraulics. Contributions addressed the methods and strategies for measuring sediment transport processes including large databases such as those from watersheds in Ontario Canada or Austrian rivers, sediment transport modelling, calibration and validation, and how results from different approaches can be used for improved management of local watersheds. On the quality side, contributions addressed the evaluation of pollution sources and the mobilisation and transport of sediment bound contaminants at the catchment scale with case studies on traditional contaminants including metals, polychlorinated biphenyls, but also acid mine drainage, hazardous substances released from water construction materials, and radioactive substances strongly attached to suspended sediment such as cesium-137. Case studies from Europe, Africa, America and Asia ensured a broad geographic coverage.

Four other sessions on the Analysis and modelling of sediment transfer in Mediterranean landscapes, Modern hydraulics structures for better hydrodynamics and hydromorphology of streams and rivers, Climate change and freshwater sediments and Climate change impacts on coastal waters and sediments also included contributions on methodological improvements and case studies on natural and anthropogenic modulation of sediment transport processes.

SedNet at the exhibition of the 6th IAHS International Conference on Water Resources and Environmental Research: Water and Environmental Dynamics

The outcome of the conference will be published as a cluster of peer reviewed papers by Springer in the book “Sediment matters: the challenges”. The book, edited by Dr. Peter Heininger (Federal Institute of Hydrology) and Dr. Johannes Cullmann (IHP/HWRP Secretariat) aims at presenting scientific progress in process and system understanding and management as well as sound foundations for policy development.

GeDSeT, a Decision Support Tool for innovative management scenarios for sediments from waterways

A decision support tool on the management of sediments from waterways was developed by the Belgian-French GeDSeT project (InterReg IV, 2008-2013; SedNet course, Ferrara 2012). This tool was built using literature reviews, new research results and extensive exchanges with the actors and stakeholders of sediment management.

The tool belongs to the family of multicriteria DSTs (Laboudigue et al., 2011; Michel et al., 2012) and is based on a “what-if” strategy, rather than offering the “best possible option”. Therefore, it allows to test innovative scenarios and to support discussions with local authorities and communities. Scenarios evaluated with enlarged system boundaries allow to identify external benefits, such as pollution mitigation, reduced minerals extraction or land use, improvement of fluvial transport or living conditions.

Fig. 1: Data and indicators for the GeDSeT tool.

Examples of innovative scenarios will be discussed at the SedNet conference in Lisbon (Lemière et al., submitted). They comprise:

Scenario 1: selective dredging
Selectively dredge first the most contaminated hotspots, then bulk dredge the remainder of sediments from the waterway section. Consequences: a) reduction of the contaminated volume to be treated or sent to hazardous waste disposal, b) reduction of the average contamination of bulk dredged sediments, c) selection of less contaminated sediment lots, acceptable for reuse.

Fig. 2: Selective dredging and detail characterisation.
Crosses: sampling points. Boxes: contour of composites currently used for lab characterisation for bulk dredging. Field characterisation of individual samples would allow selective dredging of hotspots (pink) and subsequent valorisation of less contaminated sediment (blue).

Fig. 3: Mobile sediment treatment plant

Scenario 2: on-site treatment
Process as much as posssible the sediment with a ship-borne plant. On-site dehydration allows to obtain easier output material. Consequences:
a) reduction of the dredged volume to be managed or sent to valorisation,
b) water can be returned to the waterway after treatment.

Scenario 3: selective treatment
Sediment loads are directed towards a treatment procedure adequate for their pollutant contents (inorganic and/or organic). This scenario is applicable to sediment treatment facilities currently developed near canals. Treatment may be aimed at reducing contamination under critical levels for less polluted sediments, or at concentrating the pollutants in a low volume fraction for safe disposal. Reusable sediment loads may be shipped to reuse sites.

Fig.4: Selective processing of dredged sediment loads (left) in canal-side treatment plant: uncontaminated, direct shipping to reuse site; low contamination: dehydration or landfarming until reuse (1); medium contamination: treatment and separation (2); high contamination: concentration and disposal as hazardous waste (3).

Scenario 4: alternative use of sediment
Selectively dredged or treated sediments may be directed to reuse according to contamination level and regulatory constraints. Potential uses comprise: a) bulk use where applicable (landfill cover, civil works, excavation backfill), b) composite use (mix with concrete demolition aggregate), c) use as an alternative mineral resource (cement production). Benefits include the reduction of primary minerals extraction and of sediment storage, hence increase of possible waterways dredging operations.

Scenario 5: alternative use of disposal sites
Sediment deposits are highly vegetated due to abundant organic matter, but they are unfit for food crops. Their use for energy crops (wood pellets, seeds) would reduce undesirable land use and allow energy crops on fertile soil without competition for land with food crops.

pXRF on sediments

The development of a decision support tool on sediment management led to the identification of several innovative management scenarios (ref: article GeDSeT above). Most of these scenarios require that data on the contamination level can be obtained in real time on the dredging site or at the unloading point before reuse.
Research led during the GeDSeT project showed that this can be achieved for most of the inorganic substances using portable X-ray fluorescence spectrometry on site, without waiting for laboratory analyses, provided that a simple dehydration procedure is applied (Lemière et al., in press).
For the main organic contaminants (petrol hydrocarbons, PAHs and PCBs) this is not yet possible, but the feasibility study led in the GeDSeT project allows to undertake the same approach in a daughter project (CEAMaS, 2013-2015).

Is ‘minimising the footprint’ an effective intervention to maximise the recovery of intertidal sediments from disturbance?
Phase 1: Literature review (NECR110)


Activity on intertidal soft sediments can cause damage or disturbance of the habitat from abrasion, penetration and removal. For example, vehicles used to reach cockle beds for fishing or access to structures such as piers for maintenance works.

Natural England’s advice in these situations has been based around sensitivities of habitats assessed on the MarLIN website. Generally, the advice has been that developers and developments should minimise the scale and extent, of the impact within the environment. This approach of ‘minimising the footprint’ generally leads to a more intense disturbance over a relatively smaller area. Recent anecdotal evidence suggests that recovery is quicker, and more complete, if the disturbance covers a wider area, but at a lower intensity.

This work was commissioned to review existing information on recovery of intertidal soft sediment habitats from different levels and intensities of disturbance.

Setting scientific principles for sediment risk assessment
From the newsletter of ECHA – the European Chemicals Agency

How to use science for regulatory purposes was one of the key questions tackled at ECHA’s first topical scientific workshop, held on 7-8 May 2013, which covered sediment risk assessment. The workshop brought together over 100 experts from around the world to set the scientific principles for assessing risks to the sediment compartment in all regulatory contexts.

“There have been significant developments in science concerning sediment risk assessment, which are not reflected in the current guidance,” says ECHA’s Jose Tarazona, the workshop Chair. He says that the workshop conclusions provide a good basis for reviewing the current guidance.

“Our aim was to set basic principles that could be applied in all regulatory contexts. After all, the science is the same for predictive risk assessment conducted for example for substances under REACH, and for retrospective site-specific assessments conducted on contaminated areas, for example under the Water Framework Directive. Depending on a specific regulation, the tools and methods may vary, but should be based on shared scientific grounds.”

The two-day workshop included general plenary sessions with case studies and topical breakout group sessions, where the participants discussed specific recommendations on how to use scientific knowledge for regulatory purposes.

“There were, for example, recommendations on when to trigger the risk assessment for the sediment compartment, what should be the basic principles and how to use the equilibrium partitioning method(*) for screening purposes. The participants also gave their ideas for covering the exposure assessment, predicting the concentration levels expected in the environment and reaching the sediment organisms, and elaborated on the tools that are available for describing and predicting the effects,” says Dr Tarazona.

Another conclusion from the workshop was that the risks for sediment should be considered as part of the aquatic assessment and should not be restricted to invertebrates. “The current guidance focuses only on sediment invertebrates. Obviously, the invertebrates are very relevant but there are other taxonomic groups and ecological functions that need to be considered as well,” Dr Tarazona points out.

This conclusion might mean that simply updating the guidance is not enough – a new conceptual model needs to be developed to make sure that the risks are covered for all relevant substances.

(*)The equilibrium partitioning method (EqP-method) can be used for adapting the REACH information requirements on soil and sediment testing. To derive screening environmental quality standards for soil or sediment, it uses aquatic toxicity data and a soil/water or sediment/water partitioning coefficient.

Note by SedNet: Dr Tarazona will give a key-note presentation at the SedNet conference in Lisbon on 7 November 2013.

How can we generate more public and political attention for sediment and soil management?

The AquaConSoil conference was held in Barcelona 15-19 April 2013. At this event the Dutch Deltares institute together with the Flemish MOW, OVAM, LNE and VMM organized a special session entitled “The potential for further integration of soil, sediment and water management and how ecosystem services may help”. In the session the highlights were presented of the 2012 Flanders ‘sediment day’, i.e. present the state-of-art on integrated management of soil, sediment and water in Flanders. Thereafter ample time was used for discussion with the session participants. One of the key-questions discussed was “How can we generate more public as well as political attention for sediment-soil-water management”. One of the outcomes was that it might help to jointly (the more critical mass, the better) prepare a ‘White Paper’. This paper should describe in a language understandable for policy makers what the many positive contributions are of sediment-soil-water ecosystem services to key issues that ARE being perceived as important/urgent by the public and politicians, i.e. jobs, energy, safety and health (see figure).

The feasibility of preparing such a white paper is now being explored. A nice response/quote already from Paul Nathanail (Cabernet): “Perhaps a White Paper that seeks to place soil and sediment in the resource category rather than as a hazard or something that is being threatened may make policy makers rethink.”

NATO proposal for part II sediment training course Sava river basin

In the SedNet eNewsletter of November 2012 you have already been informed on the successful outcome of the 1st part of the “practical training course on sustainable sediment management with the Sava river basin as showcase” (see also: www.savacommission.org). SedNet – in close cooperation with the International Sava River Basin Commission (ISRBC) and UNESCO Venice office – submitted a proposal to NATO (Science for Peace and Security programme) for funding the 2nd part of this course. Part II of the course will focus on measures and governance aspects. The outcome of the proposal review is expected by December this year. If the proposal is granted by NATO, than we anticipate part II of the course to be held in March 2014.

WODCON XX – World Dredging Congress “The Art of Dredging”, 3-7 June 2013, Brussels

The 20th anniversary World Dredging Congress and Exhibition, WODCON, took place in Brussels from 3rd to 7th of June. This event takes place every three years in the European, American or Asian section of the World Organisation of Dredging Associations (WODA) and is the premier dredging event for professionals from around the globe. This year’s theme “The Art of Dredging” addressed skills, craft and experience to be brought together to an intended achievement. Cees van Rhee, chairman of the technical paper committee, explained the link of dredging to art by stating that famous artist Leonardo da Vinci already designed dredging equipment in his time, combining science and art which was seen as the same discipline in those days.

In total a number of 95 technical papers were presented by delegates from all continents, covering all aspects of dredging and marine construction. They were organized in parallel sessions, one about dredging equipment and the dredging process, the other focusing on management of sediments, environmental dredging as well as sediment assessment and monitoring.

A special session was dedicated to “The dredging debate” steered by CEDA environment commission chairman Polite Laboyrie. A panel with representatives from CEDA, EADA, WEDA and PIANC got the audience to discuss about themes covering aspects of Working with Nature, Adaptive Management as well as Stakeholder Involvement. Additionally a CEDA position paper on underwater sound as well as an information paper on ecosystem services and their relevance to the dredging industry were presented.

Another special double-session was committed to dredging works in the Westerschelde. To one part the focus was on the navigation channel and the applied dredging strategy, the hydro- und morphodynamic developments and the impact of human intervention. The further part of the session focused on recent developments in the Port of Antwerp and its new treatment facility for dredged material as well as dealing with siltation rates in the new tidal Deurganckdok through construction of a new current deflection wall.

The technical tours took the WODCON visitors to travel along the Schelde and learn about the Sigma Plan for flood protection. Further a visit to the AMORAS treatment facility and the construction site of the new lock within the Deurganckdok were offered.

WODCON XX: Best Paper Award for research on long-term and far-field dispersion of finesThe best paper award was granted to Thijs van Kessel (Deltares) for his paper with co-author Bas van Maren (also Deltares) on the far-field and long-term dispersion of released dredged material.

In the paper the cumulative effect of a large number of sediment plumes on turbidity levels is analyzed. Although the dispersion of individual plumes is often considered for impact assessments, it is the cumulative effect of a large number of individual plumes that determines the impact on the long term. Resuspension from the seabed may become the dominant factor contributing to turbidity. The contribution of dredged material to the natural background turbidity depends on the type and amount of material added to the system relative to type and amount of fine sediment already present due to natural processes. The proposed methodology is applicable in systems in with a low natural percentage of fines in the bed. In this case the addition of fines (e.g. by dredging operations) is likely to increase turbidity levels as more fines become available for resuspension and transport. The paper presents examples of computations on the far-field and long-term dispersion of fines in the natural environment and their sensitivity to parameter settings such as settling velocity, critical shear stress for erosion and burial rate.

With a total of about 430 registered visitors, WODCON XX was a very successful event, especially the exhibition was the perfect place for international networking. All technical presentations will be made available to the public, please check the Conference website for details.

Karlsruher Flussgebietstage 2013 („River Basin days 2013“), 20-21 June 2013, Karlsruhe, Germany

The “Karlsruher Flussgebietstage” is a biannual international symposium held at the Institute of Water and River Basin Management (IWG) of KIT. The symposium is a platform for the scientific exchange on specific issues of river basin management.

The meeting in 2013 had a focus on solids in river basins. Solids play an important role in both ecosystems and techno sphere. They serve as transport vehicle for various pollutants and directly influence water quality, habitat conditions and biogeochemical cycles. The impact on river ecosystems is largely determined by the sources and rate at which solids are delivered to surface water bodies, their residence time in the river systems and their physico-chemical composition.

Thus the “Karlsruher Flussgebietstage 2013” were centred on sources and transport processes of solids and particulate contaminants in river basins, considering modelling approaches, data availability, new monitoring techniques and management strategies.

The 3 technical sessions were on Sources and Transport Processes, Monitoring Techniques, and Management Strategies. Presenters came from the UK, Austria, the Netherlands, and Germany. In due time the presentations can be found on the conference website.

2013 Battelle – Seventh International Conference on Remediation of Contaminated Sediments

Eric A. Stern / Research Leader – Sediment Management Battelle Memorial Institute

The 7th International Conference on Remediation of Contaminated Sediments was held February 4-7, 2013, in Dallas, Texas. In attendance there was a wide cross-section of sediment management competencies which included approximately 970 service providers – consultants, academics, government scientists/managers, product developers and regulators as well as approximately 40 students. The conference was represented from 24 nations across the globe. The Conference was co-Chaired by Andy Bullard and Eric Stern, and was kicked off by a successful Plenary Session that included an enormously well-received Keynote address given by best-selling author and swordfish boat captain Linda Greenlaw (2000 film adaptation of Sebastian Junger’s The Perfect Storm). The Conference concluded with a Café Roundtable led by Andy and Eric, where the theme of Integrated Sediment Management and the future landscape/vision of the global sediment management community were discussed.

Between open and close, the Conference technical program consisted of four instructor-led short courses, 239 platform presentations in five technical tracks, four breakout panels, and 199 poster presentations in two evening poster sessions.

From the onset planning functions for the 2013 conference it was the intent to move beyond the previous conference settings and to move in new directions. This included sediment management areas related to offshore wind development, legacy contaminants from Municipal Gas Plants, and assessments/challenges within Urban Sediment Management environments. Some of the challenges from a global perspective include:
Costs of sediment clean-ups are becoming prohibitive
 Timelines from assessment to design and construction can take a decade or more
Risk assessments are driving to unachievable clean-up standards
Innovation from typical dredge-haul-dump is lacking which leads to a lack of innovation
Regulatory programs in sediments are fragmented and un-coordinated
How is Regional Sediment Management integrated into regulatory functions?
What does it mean and how do you implement green remediation and sustainability into sediment programs (is this a paradox)?
Along these lines, Battelle set out to develop with the Conference Technical Steering Committee (TSC), panels that could start addressing these challenges. Four new innovative panels were developed to set the charge for this conference and for future dialogue.
Sediment Remediation and its Intersection with the Clean Water Act
The Realities of Bioavailability in Sediment Management
Sediment Management for Urban Rivers
The Role of Risk in Sediment Remediation
An emerging theme for this conference focused on Urban and Integrated Sediment Management. As the conference progressed during the week, this theme became more apparent in how it aligned with holistic approaches within the context of Regional Sediment Management.
For the first time for this conference, a Café Roundtable was conceived that brought closure to the conference by bringing together eight recognized specialists in sediments that could have an open, un-filtered dialogue with the audience on the vision and future of contaminated sediment management. This provided a sense of closure for the 4 days that we were together assimilating a significant amount of information. More importantly this roundtable gave a moment of pause to re-think where this discipline is going – the trans-disciplinary nature of these challenges and are there ways to approach complicated systems (including upland source control) that can be environmentally protective, economically viable (redevelopment and cost-share models), socially acceptable while reducing liability. Some thoughts/directions that came out of the Roundtable that can contribute towards development of the 2015 conference included the following:
Significant need for a better program that incorporates a more holistic approach to contaminated sediments and watershed management. The USEPA Great Lakes Legacy Act that is a cost-share Program between Federal and Potential Responsible Parties should be further explored as a component to Superfund and be populated to other US regions as well as globally.
 There is a need to better understand up front from all stakeholders what we want in the end (what is the goal/vision that everyone would like to see achieved). These are complex social and technological challenges.
Better understanding what everyone wants as an end result leads to the need to incorporate city planners, landscape architects, construction managers etc. into the process.
Proof of concept through bench-pilot-and commercial applications of innovative technologies takes too long to reach the marketplace.
Financing must be discussed at an early stage. After developing risk assessment a preliminary financing plan must be discussed together with stakeholders. A senior member of the sediment society must be involved at an early stage discussing complex social and technological issues. To this end, professional facilitation/mediation to help in dispute resolution to move sediment projects forward would be helpful.

Planning is underway for the Eighth International Conference on Remediation of Contaminated Sediments, which will be held in early 2015. We wish our colleagues and friends a great SedNet Conference in Lisbon!

5th SCARCE Newsletter now online

SCARCE is a multipurpose project that aims to describe and predict the relevance of global change impacts on water availability, water quality and ecosystem services in Mediterranean river basins of the Iberian Peninsula, as well as their impacts on the human society and economy. Hence, the project has assembled a multidisciplinary team of leading scientists in the fields of hydrology, geomorphology, chemistry, ecology, ecotoxicology, economy, engineering and modelling, in an unknown effort in the CONSOLIDER framework. The project also has the active involvement of Water Authorities and other relevant agents as stakeholders. The project has started end of 2009 and will last 5 years.

Information about Dredging
From the IADC website

IADC stands for “International Association of Dredging Companies” and is the global umbrella organisation for contractors in the private dredging industry. On its website IADC publishes several series which contain a wealth of information and which can be downloaded for free.

Facts About is a series of concise, easy-to-read leaflets which give an effective overview of essential facts about specific dredging and maritime construction subjects. Each leaflet provides a kind of ‘management summary’ for stakeholders who need a quick understanding of a particular issue. These leaflets are part of IADC’s on-going effort to support clients, consultants and others in understanding the fundamental principles of dredging and maritime construction because providing effective information to all involved parties is an essential element in achieving a successful dredging project.

Terra et Aqua, the official quarterly publication of IADC, seeks to present dredging related papers on important scientific and state-of-the-art subjects. Articles from all those involved in dredging, members and non-members, will be considered but all submissions are subject to peer review. Terra et Aqua is distributed free of charge to more than 10,000 readers world-wide and is available to anyone in the dredging industry upon request. The magazine is supported solely by the IADC as a service to the world-wide dredging community and represents IADC’s commitment to the highest standards of professional conduct. No advertising is accepted.
