The general aim of the project is to contribute to a better quality of surface and groundwater bodies in the Scheldt International River Basin District (IRBD). This will be done by developing and implementing a set of cost-effective. innovative and transnational actions aimed at attaining a good status of surface and groundwater bodies. By monitoring the transnational effect of these actions. the foundation for the development of a transnational surveillance system for the Water Framework Directive (WFD) programmes of measures for the Scheldt IRBD will be laid. With this project aim. the Scaldwin-project capitalises on the results of the Interreg IIIB NWE Scaldit-project. The pressure on the water system differs between regions. Most of the investigated transboundary or similar surface waters and groundwater layers are at risk of not achieving a good status as asked by the WFD. All competent authorities of the Scheldt IRBD will have to take extra measures. This project aims at finding the best available measures to improve surface water. sediments and groundwater. To reach this overall aim. five objectives were defined: 1. Improving the ecological status of surface water bodies based on river ecosystem development and biodiversity enhancement (WP1) 2. Improving the ecological status of surface water bodies based on sediment management (WP2) 3. Sustainable water resources management for groundwater bodies (WP3) 4. Assessing the implementation of the WFD programmes of measures (WP4) 5. Raising public awareness (WP5) Achievements: • Website in Dutch, French and English: http://www.scaldwin.org• Two times an International Week for the Scheldt River: http://www.scheldeweek.org• Information map on the ScaldWIN-actions: http://www.scaldwin.org/project-EN/documents/scaldwin-map• Promotional youtube channel for International Scheldt Week: http://www.youtube.com/user/ISWSIE2013
