Website: www.SedNet.org<\/a> <\/p>\n <\/p>\n From 3-5 April 2019 the 11th<\/sup> International SedNet Conference Sediment as a dynamic natural resource – from catchment to open sea<\/strong> will be organised in Dubrovnik, Croatia. Co-organisers are Ru\u0111er Bo\u0161kovi\u0107 Institute and University of Dubrovnik, and IAEA is giving support.<\/p>\n Sediments found in upland streams, industrialised waterways, busy coastal zones and offshore waters are characterized by a wide variety of sediment properties present in dynamic and less dynamic areas. These areas are inherently interlinked as sediment is transported from catchment to the open sea. The natural flow of sediment from mountainous regions to the ocean is strongly impacted by anthropogenic activities along this journey in terms of both the quantity that is transported and the quality of transporting waters. Sediment distribution is not only impacted by direct human influence but also indirectly as a result of changing weather and climate patterns. A change in sediment dynamics leading to sediment starvation or sediment accumulation is often the concern of river basin and coastal managers who constantly need to adapt to these environmental variations. Historical or emerging contaminants may also hinder the management of these areas.<\/p>\n At the SedNet 2019 conference \u201cSediment as a dynamic natural resource \u2013 from catchment to open sea\u201d, we invite abstracts for a series of sessions aiming to explore these challenges and proposed solutions. This includes how policies and plans are developed for the range of often interlinked issues experienced along the journey from upland areas to the deeper waters such as how sediment quality should be assessed, sediment as an ecosystem service and how excess sediment can be used beneficially. The challenges posed as a result of anthropogenic influences, resource exploitation and climate change shall also be explored as well as emerging problems being examined such as contaminants resulting from discharge of waste.<\/p>\n The proposed thematic sessions are:<\/p>\n Deadline for submission of abstracts:<\/strong>\u00a0\u00a01 October 2018<\/strong><\/p>\n Abstracts will be selected by the SedNet Steering Group for either a platform presentation or a poster presentation.<\/p>\n Please see https:\/\/sednet.org\/sednet-conference-2019\/<\/a> \u00a0for the full text of the Call and the template for submission of abstracts to the SedNet Secretariat: marjan.euser@deltares.nl<\/a><\/p>\n <\/p>\n <\/p>\n On 7-8 March 2018 a workshop of the SedNet Working Group Sediment Quantity was organised at Deltares in Delft. Approx. 25 participants attended the workshop. For background information about\u00a0the WG we refer to the February-2018 edition of SedNet eNews.<\/p>\n The result of the event is a variety of practicle and feasible ideas and actions:<\/p>\n <\/p>\n <\/p>\n The Working Group is chaired by: The next workshop will be held on 5-6 November 2018 in Hamburg, Germany.<\/p>\n If you are interested\u00a0in getting involved, feel free to contact the SedNet Secretariat.<\/a><\/p>\n <\/p>\n <\/p>\n In order to promote the reuse of sediments for sustainable purposes, SedNet will open on its website a resources library containing good practice guides, and more. Three such guides exist in French<\/a> and we wish to translate them in English. <\/p>\n <\/p>\n The EU Water Framework Directive promotes a holistic, transboundary approach to European river catchments. The Federal Institute of Hydrology (BfG) and the Institute of Hydraulic Engineering and Water Resources Management of RWTH Aachen University (IWW) have compiled the first sediment budget of the entire Rhine channel from its source in the Alps to its estuary in the North Sea. The study was conducted under the banner of the International Commission for the Hydrology of the Rhine Basin (CHR) and is now published as the 22nd<\/sup> CHR-report.<\/p>\n Schematic representation of the sediment budget terms of a river section.<\/p><\/div>\n The report presents a unique, detailed, and grain size fractionated analysis of the morphology of the entire river Rhine, one of the world\u2019s larger rivers. The objectives were: (a) to quantify the downstream fluxes of clay, silt, sand, gravel and cobbles and (b) to identify the sources and sinks of these sediments. A large number of morphological studies about the Rhine were reviewed and existing data, such as echo soundings and sediment transport data from the period 1991 to 2010, was re-analysed.<\/p>\n The following conclusions were drawn: (1) Sediment fluxes in the Rhine are discontinuous due to regional sinks and sources, leading to a large variability of the sediment fluxes along the river channel. (2) From source to mouth, the Rhine traverses four sections with fundamentally different morphodynamic behaviour: the Alpine, impounded, free-flowing and delta sections. (3) The largest sediment fluxes, which are dominated by the clay fraction, are observed in the Alpine section. (4) Nourishment represents the biggest source of gravel and cobbles, while tributaries are the biggest fluvial source of clay, silt and sand. In addition large amounts of clay, silt and sand are supplied to the lower Rhine delta by the sea. (5) Dredging represents a main sediment sink for all size fractions. For silt and clay, deposition in floodplains and ports represent an additional major sediment sink. Sediment output to the North Sea is limited. (6) In contrast to the typical prototype of a river with erosion in the upper reaches and sedimentation in the lower reaches, the Rhine has net deposition in the upper reaches and net erosion in the downstream reaches. Local variations are high though. (7) More sediment is transported upstream from the North Sea into the lower Rhine delta than vice versa. (8) Floodplain deposition causes a higher loss of sediment in the upstream parts of the river than in the delta. (9) Today\u2019s sediment fluxes in the Rhine are strongly influenced by river training works from the past, as well as by dredging and nourishment operations. (10) Yet natural factors determine the large-scale, primary location of the main sedimentation areas. (11) In many reaches gravel is deposited, whereas sand is being eroded simultaneously. (12) The budget analysis shows that sediment dynamics in rivers are much higher than is suggested by echosoundings or transport measurements, and it also shows that (13) sand plays a dominant role in the morphodynamics of the Rhine, not only in the sand-bed reaches, but also in the gravel-bed reaches of the river. (14) The sediment budget derived in this study provides very valuable empirical evidence for improving numerical prediction models, optimizing nourishment, dredging and monitoring strategies, and for discovering knowledge gaps and setting research agendas to facilitate the cross-boundary and sustainable sediment management along the river Rhine.<\/p>\n The full report is available at: http:\/\/doi.bafg.de\/BfG\/2017\/KHR_22.2017.pdf<\/a><\/p>\n <\/p>\n avec le soutien du fonds europ\u00e9en de d\u00e9veloppement r\u00e9gional Project partners INERIS, Lille University, VNF, BRGM led in March 2018 a characterisation and sampling campaign on the historic sediments storage site TD 26 operated by VNF (French Waterways Agency) near Saint Omer, Northern France, along the channelised Aa river. Laboratory support is provided by Belgian partners ISSeP and CTP, and French partner Mines Douai. <\/span><\/span><\/p>\n The objective of this campaign is to evaluate historic dredged sediments for their suitability for reuse through pilot projects (civil engineering and road works concrete, cycle path base, landscaping mounds) that will be undertaken during the project. It focussed on potential environmental issues and on site homogeneity. It addressed both solids (matured sediments) and shallow water.<\/span><\/span><\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n Results show that the sediments would qualify as non hazardous or inert under waste regulations for most regulated metals and metalloids. Organic contaminants will be analysed in the laboratory. The campaign allowed testing new on-site electrochemical analytical techniques (trace elements in water, sulphides). <\/p>\n \u00a0<\/strong><\/p>\n WRF 2019 will host a series of \u2018deep-dive\u2019 workshops as part of the conference program and invites interested organisations to design and submit a workshop proposal. Under the Title ‘Closing Loops – Transitions at work’, WRF 2019 wants to show systemic drivers, as well as concrete solutions to make the transition to circular economy work in practice.<\/p>\n A circular economy aims at maintaining our resources, such as materials, land and soil, at a high quality level while rendering the services we need to fulfill our current and future needs. This can be achieved by reorganising production\/consumption patterns and value chains so that resources do not get wasted, rather get replenished and restored.<\/p>\n Workshops address topical issues related to the 6 conference themes:<\/p>\n For further information see: http:\/\/www.ovamenglish.be\/design-your-own-workshop<\/a> and http:\/\/www.ovamenglish.be\/soil-and-land-as-a-valuable-resource<\/a><\/p>\n <\/p>\n <\/p>\n River Restoration: Fluvial-Geomorphic and Ecological Tools, <\/strong>11-15 June 2018, Beaumont du Ventoux, Provence, France Sediment Transport in Stream Assessment and Design, <\/strong>30 July – 03 Aug\u00a0 2018, Logan, Utah USA Geomorphic and Ecological Fundamentals for River and Stream Restoration, <\/strong>6-10 August 2018, Truckee, California USA If you have questions, please contact us at <river.restoration.sagehen@gmail.com<\/a>><\/p>\n <\/p>\n The JRC in collaboration with the University of Basel and the Universite Catholique de Louvain have quantified the potential spatial displacement and transport of soil sediments due to water erosion at European scale. Long-term averages of annual soil loss and deposition rates were computed by means of the extensively tested spatially distributed WaTEM\/SEDEM model. According to a recent research<\/a> study in Europe, the estimated sediment yield totals about 164 \u00b1 13 Tg yr-1<\/sup>. The Sedi\u00adment Delivery Ratio (SDR) i.e., the ratio between sediment yield (SY) and gross erosion, indicates that the sediment routed down the hillslopes to the riverine system accounts for 15.3% of the total eroded soil.\u00a0Further improvement of the calibration scheme in the model transport parameter is foreseen to better reconcile the good agreement between predicted and measured sediment yield. The net erosion and sediment transport data are available (100m resolution) in ESDAC.<\/a><\/p>\n <\/p>\n 4-8 June 2018: 3rd edition of the\u00a0I.S.Rivers international conference\u00a0<\/strong>on integrative sciences and sustainable development of rivers, Lyon, France.

It\u2019s a great opportunity to make connections with others working on similar issues in different geographic and institutional settings.\u00a0 Held the week after ISRivers, it offers a great opportunity to combine two professional and education experiences in a compelling setting. \u00a0(in English)<\/p>\n
\nhttps:\/\/qcnr.usu.edu\/courses\/sediment_transport<\/a>
\nThis course is intended for those who wish to understand and apply the principles of sediment transport to alluvial channel assessment and design. Principles of open channel flow and sediment transport are combined with watershed-scale, hydrologic and sediment source analysis to place channel assessment and design in context. The course balances advance reading, lecture, field work, and hands-on exercises for estimating sediment supply, calculating sediment transport rates, forecasting channel response to water and sediment supply, and channel design. Intended for participants familiar with basic principles of river geomorphology (such as from the Beaumont or Sagehen courses). Instructors are drawn from both research and practice. Continuing Education Units for the course offered by Utah State University.<\/p>\n
