November 8COP26 Sediment Management Press Release.

In November 2021, at COP26 in Glasgow, the world took some further steps towards addressing the climate change and ecological crises.

Oceans, coasts, waterways and their associated ecosystems now feature explicitly in the text of the COP26 Decision, for example, the Decision: “Emphasizes the importance of protecting, conserving and restoring nature and ecosystems, including forests and other terrestrial and marine ecosystems, to achieve the long-term global goal of the [UN Framework Climate Change] Convention by acting as sinks and reservoirs of greenhouse gases and protecting biodiversity, while ensuring social and environmental safeguards”

Sediments are not mentioned by name, but sediments act as the building block for many coastal and aquatic habitats. Sediments and their related habitats also sequester and store carbon, acting as a vital sink for greenhouse gases.

If you work with sediments and you want to make a difference, encourage your organisation to endorse our COP26 Sediment Management Pledge!

Details about the COP26 Sediment Management Pledge can be found at:

A Catalogue of Nature-Based Solutions for Urban Resilience

The Catalogue was developed by the World Bank’s Global Program on Nature-based Solutions (GPNBS) and the City Resilience Program (CRP), under the leadership of Sameh Wahba,
Global Director for Urban, Resilience and Land; Niels Holm-Nielsen, Practice Manager of the Global Facility for Disaster
Reduction and Recovery (GFDRR); and Meskerem Brhane, Practice Manager for Urban, Resilience and Land, East and
Southern Africa.

NovemberRestoring Estuarine and Coastal Habitats with Dredged Sediment – CaBA (
This handbook provides conceptual, practical and regulatory guidance on the beneficial use of sediments arising from dredging activities across the UK.The handbook is one of a quartet of restoration guidelines, developed alongside those for native oyster reefs, seagrass meadows and saltmarshes.Partners: Environment Agency, Cefas, ABPmer.
October 22An outcome of the virtual workshop ‘Sediment management opportunities to address the climate change challenge’ hosted by Navigating a Changing Climate and SedNet is an ambitious but realistic – and very necessary – COP26 Sediment Management and Climate Change Pledge.

Please contact the SedNet Secretariat if your organisation wishes to endorse the COP26 Pledge. See the News-item for details.

NovJSS Open-Access papers on sediment
All 7 papers from the December-2020 issue of the Journal on Soils and Sediments on “Advances in sediment science and management” are now available on the JSS website and all but one are open-access and available to all:

  • Soil erosion and sediment dynamics in the Anthropocene: a review of human impacts during a period of rapid global environmental change
  • Characterisation of road-dust sediment in urban systems: a review of a global challenge
  • River and harbor remediation: “polluter pays,” alternative finance, and the promise of a “circular economy”
  • Ecotoxicological testing of sediments and dredged material: an overlooked opportunity?
  • Including sediment in European River Basin Management Plans: twenty years of work by SedNet
  • Sediment source fingerprinting: benchmarking recent outputs, remaining challenges and emerging themes
  • Linking temporal scales of suspended sediment transport in rivers: towards improving transferability of prediction
OctSummary report workshop on “The Role of Ecotoxicological Data in Sediment Quality and Dredged Material Assessment Frameworks”, held online on 1-2 October 2020

MayBeneficial use of dredged sediments in road engineering
This Methodological Guide 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.

June, 20Moving Sediment Management Forward – The Four SedNet Messages
SedNet started in 2002 as a Thematic Network on contaminated sediment, funded by the European Commission. Since 2005, SedNet has continued independently with partners from organisations representing science, management and administration. SedNet broadened its scope to cover all aspects of sediment, from the river to the sea.
During the last decade SedNet has organised eight international conferences. Two Round Table events brought together international experts from several European river basins.
Based on this experience and associated discussions, the SedNet core group identified four key messages related to sediment management and these are presented in the brochure “Moving Sediment Management Forward” (pdf).
The four key messages can be condensed to one overarching message: Sediments are an integral part of nature and aquatic systems; they are an important resource which needs protection and targeted management.
This brochure was prepared to promote the four key messages at European and national level. The reader is encouraged to make use of it. Enjoy reading the brochure, and SedNet will be happy to discuss sediment management directly with you!
Case studies (pdf) which exemplify the key messages can be found here:

Case Elbe
Case Meuse
