The project aims to improve flood prevention and management in the North Sea Region (NSR) through BwN. BwN will be demonstrated in all 7 NSR countries: N, SE, DK, D, UK, NL, B along a range of water bodies (coast, estuary, rivers, lakes). Existing investment projects will be leveraged and enriched with transnational best practice, performance monitoring, cost-benefit analysis and business case generation. Lessons are scaled-up to national policy, practical guidlines, and references for international business development. FHR is involved as an observatory of the project and it will support Coastal Division with expertise regarding the beach nourishment. The selection of Mariakerke as a pilot site in the frame of this project makes a strong connection with project 00_128 ”Vooroever- en geulsuppleties als kustbescherming”.
