The rivers which are the central subject of this project are mainly diked in order to ensure sufficient flood protection. The alluvial plains between the dikes grow constantly due to sedimentation which leads to the problem that the flow profile originally calculated is decreasing. This development is additionally enhanced through the natural succession of the alluvial plains. The whole process multiplies the risk, that the present dikes are not able to prevent future flood disasters. The authorities responsible are the water management agencies. As preventive measures, they have so far cleared alluvial plains and increased the water flow rate in riparian woods. However, these clearing activities (for example tree clearing) become more and more in contradiction to nature protection goals and existing regulations (NATURA 2000 and the respective national protection regulations). The need for integrated strategies is increasing. Expected Results: The project will, for the first time ever, present co-ordinated implementation procedures, tackle transborder river catchment areas as well as develop joint management plans. Furthermore, it will provide: - A catalogue of relevant 2D hydraulic measuring parameters, - An information system for the calculation of the stream flow taking into account plant cover, sedimentation, river flow obstacles, summer dikes, etc., - Agro-economic management and steering instruments for sustainable use of alluvial plains in diked river areas, - Development of perspectives for different types of alluvial plains, - Testing of implementation strategies for an optimised use of alluvial plain areas in the respective parts of the rivers taking into account national legal requirements, - Information material and signs reporting on compliance of land use with NATURA 2000 and the improved river flow management, - Model plans for beaver management and protection measures for dikes and beavers in compliance with NATURA 2000, - For an integrated improvement of retention capacity and re-establishing of the connection between river and backwaters, - Concrete measures to ensure water quality on the basis of data monitoring.
