Workshop NavClimate-SedNet 10-11 Feb 2021

Online workshop Sediment management opportunities to address the climate change challenge.
The workshop is organised by the Navigating a Changing Climate partners with the collaboration of SedNet.
The workshop will comprise two consecutive half-day sessions.  Its aim is to facilitate knowledge exchange, disseminate good practice, highlight opportunities, and identify gaps in understanding or research needs in relation to the four topics mentioned below, with an emphasis on ports, waterways, dredging and associated infrastructure/ activities.
It promises to be an inspiring workshop for sediment practitioners (policy and management) as well as scientists. Invited key-note speakers and selected abstracts will address in the following (non-parallel) sessions – with room for Q&A – these four topics:

1. Role of sediment management in carbon sequestration and storage: opportunities to contribute to a net reduction in greenhouse gas emissions;

2. Sediments and climate change adaptation: seeking flexible and adaptive solutions to strengthen resilience and adapt port and navigation infrastructure and operations;

3. Habitat enhancement and creation, Working-with-Nature and other nature-based solutions;

4. Sediment management, circular economy and the waste hierarchy: reduce, reuse, recycle.

The four workshop sessions conclude with a panel discussion and an interactive session with the audience to determine:

– Key climate change-related challenges for sediment managers;

– Key opportunities for sediment management to contribute to addressing the climate change challenge;

– Key topics for further research and development.

For more detailed information on this workshop see the Programme.

Reminder: 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 (Susanne.heise@haw-hamburg.de).

Next meeting SedNet WG Sediments in Circular Economy:
15-16 April 2020, Glasgow, UK 

Following the success of the meeting WGCE3 in Bremen and Delfzijl, the SedNet Working Group “Sediments in Circular Economy” will meet again in Glasgow, Scotland, UK, with time for topic discussions and for field visits. The meeting is hosted by the University of Strathclyde.

As usual, participation is free but subject to prior registration with the SedNet Secretariat. Participants are expected to cover their travel and accommodation expenses.

The program is not yet final, but the following topics and visits are planned:

Day 1: 15 April 2020 (from 9:00 to 18:00 hrs)
Workshop: PFAS and TBT in sediment (maybe also a feature on sediment beneficial use un the Great Lakes, USA)
Site visit: Bowling pilot testing (SURICATES project) – a paper on this site was given at the conference of SedNet in 2019 in Dubrovnik.

Day 2: 16 April 2020 (from 9:00 to 18:00 hrs)
Workshop: Emerging compounds in sediment legislation
Also a feature on Mass stabilization of sediments
Group work for a paper on emerging contaminants
Site visit: Greenock (Kingston Basin) and return to Glasgow around 18:00

Join us for a memorable Scottish trip!

Please inform the SedNet Secretariat if you wish to participate to this event.

Travelling:
from Glasgow Airport there is a good bus-connection with the city centre. The airport bus (number 500) runs to and from the terminal and George Square every 10 minutes and takes 15 minutes (allow 30-40 minutes at peak times).  Buscompanies CityLink and Megabus both go from Glasgow Buchanan bus station to Edinburgh Airport, which has more options for European flights.

Hotel accommodation:
We advise you to book a room in Premier Inn (3*) Glasgow Centre (George Square) – which is nearest to the meeting venue. If you prefer a 4* hotel, the nearest is probably the Millennium Hotel on George Square.  Likewise, the Queen Street Travelodge is 2* and nearby.

12th International SedNet Conference, Lille, France

The next SedNet conference will take place in Lille in 2021. Both the exact date and location are still to be decided. We expect to have more news before summer. Keep an eye on the conference webpage.

Navigating a Changing Climate conference at COPEDEC

On 19 and 20 November 2020 Navigating a Changing Climate initiative organises a conference in The Philippines, hosted by The Philippine Ports Authority.

The Navigating a Changing Climate’s Action Plan recognises the important role of sediment in many places:

  • Mitigation, notably Blue Carbon – the role of sediments in the support and management of coastal habitats as important carbon sinks; carbon offsetting opportunities
  • How dynamic natural systems, including sediments, might be affected by climate change with potential consequences and challenges for navigation efficiency and safety; related monitoring and adaptive management responses
  • Adaptation and resilience – the role of sediments in sustaining, enhancing or creating habitats that capitalise on natural resilience or help strengthen resilience against the effects of climate change; Working with Nature

The SedNet community might therefore be interested in submitting abstracts against any of the following conference themes:

  • Moving towards ‘net zero’ emissions of greenhouse gases from port infrastructure including the port estate
  • Intermodality and system-level climate change resilience
  • Monitoring and adaptive management for responding to change
  • Climate change adaptation, including theory and practice, methodologies and case studies
  • Optimising operational resilience, including the role of inspection and maintenance
  • Flexible and adaptive infrastructure design; Nature-based solutions to improve navigation infrastructure resilience

See for details NaCC website. Deadline for submitting abstracts is 21 February 2020.
 

NaCC Website update and a call for newsletter articles

SedNet is supporter organisation of Navigating a Changing Climate. NaCC informed us that its Climate website has been updated to include a more obvious keyword-based search facility that enables you to identify items of particular relevance from the newsfeed and other pages on the site. For example, you may be interested in sector-specific articles on ‘adaptation’ or ‘decarbonisation’ or you may specifically want to understand what ‘guidance’ exists.  Please take a look at the site, including the search feature, and let us have any feedback!  It would also be useful to hear from you what other information you would like to see on the website.

PIANC workshop “Opportunities and Barriers to Beneficial Use of Sediments”

On 30 January 2020, through the Working Group 214 on Beneficial Sediment Use (BU) of PIANC, a workshop was organized in which 35 participants focused on the opportunities and barriers to beneficial use with focus on North Europe. Participants included ports, dredging industry, academics and regulators, who shared their perspectives from the dredging, regulatory, technology, and program communities in dedicated panels. This workshop follows a similar event organized in October in Brisbane dedicated to Australia. A follow-up workshop will likely be organized in Manila aside to the PIANC Copedec 2020 conference, with emphasis to South-East Asia. These regional governance perspectives will be an integral part of the final WG214 2021 report.

Annually, billions of cubic meters of material are dredged globally to maintain ship movement for commerce and recreation. Navigational maintenance is integral to the world economy, without which the transport of cargo, large cruise ships, and pleasure craft could not function. With dredging comes a need to manage dredged material. Today, many constraints pose challenges to the beneficial use of dredged material due to concerns over impacts to surface waters, displacement of aquatic habitat, or the release of contaminants into the environment. These growing constraints and societal needs motivate the development of innovative and sustainable alternatives, including identifying beneficial uses for sediment to increase value regarding economic, social, and environmental benefits. Yet, sediment is a valuable, often scare, resource in the context of sustainable development and climate adaptation. Beneficial use is naturally aligned with sustainability, life-cycle analyses, and circular-economy frameworks. Shoreline environments benefit from a system-wide evaluation of sediment dredging and dredged-sediment applications, where dredged sediment is viewed not as waste and instead is valued resource for raw material to maintain hydrological, ecological, and economic conditions. Sediments can be beneficially used to e.g. counteract coastal erosion, provide locally produced building material to raise dikes, re-establish wetlands or natural habitats, and reclaim land.

The objective of WG214 is to provide technical information and guidance regarding the state of the practice for sediment use as a beneficial resource, drawing from existing approaches and best practices. WG214 is developing a report that will consider and evaluate the following: Concepts of sediment use and existing scientific knowledge related to different uses; sediment contamination and how contamination can constrain sediment reuse alternatives; and cost-benefit and ecosystem-services frameworks to understand how the value of different reuse options can be quantified, and compare different beneficial use alternatives and compare those alternatives to the status quo. The report will give an overview of global sediment beneficial use practices, technologies, regulations, and limitations. Case studies will be presented to illustrate recent successes and challenges associated with the beneficial use of dredged material. Beneficial use must be framed in the context of LC/LP and OSPAR legislations, and the report will link to relevant reports published by PIANC, the Central and Western Dredging Associations (CEDA and WEDA), the International Association of Dredging Contractors (IADC), and the European Sediment Network (SedNet), among others.

IMMERSE
Transnational Estuary Exchange Lab

The project IMMERSE 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 second Transnational Estuary Exchange Lab on 1 – 2 April, 2020 in Groningen, the Netherlands. 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. It is the second in a series of region-wide events organized by the IMMERSE project (information and outcomes from the 1st TEEL, held in June 2019, is available here).

The upcoming Transnational Estuary Exchange Lab (TEEL) will focus on issues relevant to the nearby Eems estuary and across the North Sea region, with sessions on sediment management, silt & ecology, and governance. Please see the draft programme attached or online 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. I invite you or your relevant colleagues to participate. More information, including registration and travel information, is available on the event page.

See also the North Sea Region Estuary Managers LinkedIn Group – which is a dedicated group for the estuary managers community working in the North Sea Region –  led from the perspective of the IMMERSE project but with the aim of consolidating all kinds of relevant information and initiatives. You are most welcome to join the group!


NUREDRAIN filter technologies

The NUREDRAIN project is developing and piloting filter technologies and filter materials which can remove and/or trap nitrogen (N) and phosphorus (P) before they reach receiving agricultural waters and cause eutrophication. Below is a link to their newsletter, which will update you on recent developments and the results of their latest filter system tests:  https://conta.cc/370jqfu

The Sullied Sediments  project has a reciprocal agreement with the NUREDRAIN project to share respective successes and achievements. Our NUREDRAIN colleagues have provided input on various aspects of our project, including testing the efficacy of our new phosphate ‘dipsticks’ in the field.

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)

And:

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)

And:

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)

And:

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)

And:

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.

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.
