The last major floods on the Danube (2013) and Morava (2006) made it clear that flood protection is of great importance for the border region. Those responsible on both sides of the river must work together intensivel in order to build a sustainable flood protection system. ProDaM aims to optimize joint flood management at the Danube and Morava bordering rivers. Subgoals: Building a common data base (terrain model, hydrodynamic 2D model), Analysis and building a common understanding of residual risk and management, Minimization of flood-induced impacts on agricultural land, Planning of measures for flood protection. The project covers the entire Morava and Danube border area including flooding areas. The first phase (AP3) includes the terrain data survey. This will be done by means of laser scanning by aircraft as well as locating the riverbed flow by echo sounder by ship. A digital terrain model and subsequently a hydrodynamic 2D model will be created with the help of this data. In the second phase (AP4 to AP6), the model will be used to formulate questions on the residual risk and dimensioning of flood defenses as well as measures planning. The project results will be available to experts, universities, local authorities, etc. The implementation of measures in order to reduce flood damage benefits the local population. The project achieves the following sustainable results: Joint investigations of the residual risk cases (within the meaning of the EU Flood Directive (HW-RL)), Protection of the border regions by joint flood protection systems (within the meaning of the EU HW-RL), ProDaM will increase the institutional capacity of the relevant hydraulic engineering authorities and common solution strategies in the sense of an efficient public administration will be developed
