Abstract : Introduction: The management of marine sediment is a major issue for many European countries, and a range of different sediment management challenges have to be addressed across Europe. The volume of sediment to be dredged, the level of contamination and the physical properties of sediments vary widely in North Western Europe countries, in addition to the risk and potential cost of not dredging. In addressing these issues and its own history, each country has developed its own regulatory system and direct comparison between countries is both difficult and challenging. Methods: Regulations and direct costs for the management of dredged material are well known, and are strong drivers for decision making, but the importance of indirect costs and ensuing benefits are now recognized although they have generally received less attention to date. Is the perception of dredged sediment reuse options by European stakeholders different in North Western Europe countries? How to strengthen indicators for a sustainable reuse of dredged material? How to help stakeholders to take decisions for dredged material reuse? What is the global impact in terms of economics and the environment for dredged material reuse options? In this context, the CEAMaS Interreg IVB project has taken a multidisciplinary approach involving eight partners from Belgium, France, Ireland and the Netherlands in collaborative research and development to produce analyses and decision tools to support and facilitate stakeholders in strengthening reuse options. Results: This European project develops shared analyses regarding the perception of sediment reuse in Europe by stakeholders, technical issues for application and sediment characteristics analysis, Life Cycle Assessment for dredging and treatment techniques, and economic modeling for several reuse options or geographic-based (GIS) technologies for the evaluation of economic opportunities. These shared analyses will allow the development of a range of online decision tools and case studies, available through the CEAMaS website and a future European Center of Resources for sediment reuse. This communication will describe the global approach and findings in the CEAMaS project in this global field of investigation. The CEAMaS project involves a cooperation between CD2E as lead partner,
