The current DTP-Danube Floodplain Project (DFP) links attempts of improving flood retention and restoration, while water quality is not yet in focus. IDESproject aims to add water quality targets to this effort and improve water quality by developing an integrative floodplain management based on Ecosystem Services (ES). The transdiciplinary nature of the project links aspects related to the management of flood plains for both water retention (management) and improvement of water quality through the reduction of nutrients.
