Sediment is an important asset of the trilareral Wadden Sea. For nature and for human demands. In the three countries there is a lot of knowledge and knowhow about the behaviour of sediment (sand and mud) and the management of it. The Programme towards a rich Wadden Sea took the initiative to start a Community of Understanding (CoU) Sediment Solutions. The Common Wadden Sea Secretariat, Deltares, Rijkswaterstaat and more and more people and organizations of the trilateral Wadden Sea get involved. The CoU itself is still under development. Events like webinars helps to identify shared interests and the best way to move forward, also related to the existing organizational structures of trilateral cooperation. This webpage and its subpages is for now the spot where shared information in the CoU will be available.
Sediment Solutions Excursion 2021
During the excursion program from October 7-9, 2021, we had a very interesting program thanks to the efforts of all speakers and the organization team. We visited various locations in the estuaries of the Elbe, Jadebusen and Weser and Ems Dollard. There was an intensive exchange of knowledge and insights, and an opportunity to get to know each other.
The combination of the site visits taught us about the challenges and opportunities of sediment management on the coast of Lower Saxony and its estuaries.

Where mud matters
The current silt dynamics in the Wadden Sea are markedly influenced by human activities and interventions, such as the dredging of waterways and the use of silt for land reclamation. In this context, ‘silt’ is taken to mean sediment with a grain size of less than 63 micrometres. For the trilateral Wadden Sea (the overall Wadden Sea area shared by the Netherlands, Germany and Denmark) there is a lack of solid insight into silt management. This inspired the Wadden Academy and Programme towards a Rich Wadden Sea (PRW) to ask Deltares to launch a study into this. Where does the silt come from, what happens to it in the Wadden Sea and what are the potential consequences of human intervention?The report Where mud matters provides the first silt balance assessment for the trilateral Wadden Sea. The report was presented to Bernd Scherer, chair of the Triliteral Programming Committee on Wadden Sea Research, during the 2nd Sediment Solutions webinar.

On the webpage Factsheets Sediment Solutions you will find a combined version of the separate developed draft factsheets of trilateral Wadden Sea near-coast sediment solutions. And the factsheets as separate documents.
