In Bavaria, WaSiM setups for all subregions already exist, but ClimEx will provide one single project setup for the entire Bavarian domain (hydrological Bavaria) at a very high resolution of one to three hours and 500 meters. In combination with the climate input data (both RCM data and reference dataset) a unique model design will enable new analyses in flood forecasting. This includes the development of a Virtual Perfect Prediction tool to assess hydroclimatic preconditions (intense/long lasting precipitation, saturated soils, etc.) leading to floods.
