The floodMap Toolbox for flood hazard maps (HWGK) automates processing from the transfer of hydraulic result data to the depiction of plausible flood areas and depths.

Flood hazard and risk maps are important components of floodwater management and preparedness. They are prescribed by the Federal Water Resources Act (WHG § 31) and the European Floods Directive 2007/60/EC. Compliant flood hazard maps and protection concepts are currently being prepared for locations such as the states of Hesse, Schleswig-Holstein and Hamburg. These include transnational projects such as SAFER in Baden-Wuerttemberg and TIMIS in Rhineland-Palatinate.

The floodMap Toolbox for flood hazard maps (HWGK) automates processing from the transfer of hydraulic result data to the depiction of plausible flood areas and depths. Hydraulic results of 1D-, coupled 1D/2D- or 2D-models are processed. Key features of the optimized workflow are the TIN-based intersection and the analysis of the flood areas and depths. The analysis is based on geostatistical and spatial parameters such as area size, water depth and connection to the river system. The result of each processing step can be controlled as needed by means of a hydraulic plausibility check and then corrected manually. Thus at every point in time, inaccuracies in the data basis (such as those of the DTM) can be compensated and hydraulic exceptions can be incorporated into the calculated flood areas and depths.
