Global climate change has also increased the risk of flooding in Germany. In particular, short and intense rainfall, so-called heavy rainfall events, are increasing in frequency and extent in small-scale regions. The consequences are flash floods with a potentially high level of damage. This can be countered by using accurate and up-to-date geodata to assess potential risks in the best possible way, both in the long and short term. The Federal Agency for Cartography and Geodesy (BKG) has produced information maps on heavy rain hazards for Germany in close cooperation with the relevant federal and state authorities. The maps were calculated on the basis of long-term observations of precipitation, terrain data and a hydrodynamic model for two static precipitation scenarios. In the next step, short-term forecasts for regional results are to be calculated dynamically in cooperation with the German Weather Service (DWD). For this purpose, the BKG is using its Digital Twin Germany, which is currently under construction. Translated with DeepL.com (free version)
