Flood risk maps and flood risk maps 2019 (Environmental Atlas)

Directive 2007/60/EC of the European Parliament and of the Council on Flood Risk Assessment and Management (HWRM-RL), adopted on 23.10.2007, has been in force since 26.11.2007. The preparation of the flood risk maps and flood risk maps (HWGK and hwrk) is the second implementation step of the HWRM Directive and forms the basis for the subsequent update of the flood risk management plan by the end of 2021. HWGK describes the spatial spread of flooding as well as the water depth of a flood in various flood scenarios. The hazard maps depict floods caused by a flood of a water body itself. Floods caused by capacitive overburdening of wastewater plants, groundwater coming to light, failure of water-management dams or heavy rain are not shown in the HWGK. Hwrk provide information on the potential flood-related adverse consequences of these flood events in relation to the protected goods defined in the European HWRM Directive.
