SedNet provides a European platform where organisations responsible for the sustainable management of river basin/fresh water body related sediments and dredged material (problem owners) can meet and communicate with organisations (problems solvers) that help to provide solutions to their problems, in the form of tools, knowledge, technologies and expertise needed for that management. This platform supports, catalyses, optimises or facilitates: (1) demand driven research activities, (2) exchange of information between these activities, (3) co-operation between problem solvers and problem owners, (4) dissemination to, and exploitation of knowledge by problem owners, (5) publication of research results and (6) inform public and decision-makers. Furthermore, SedNet aims to complement existing EU networks and thematic working groups and aims to be an advisory board to European, national and regional authorities on sediment issues, and indirectly assist with their policy implementation.
