Summary

The goal of this project is to develop a demonstrator for an "information platform on meteorological-hydrological forecasts and warnings in small catchments" that also evaluates and communicates the uncertainties in the forecasts of precipitation and runoff. The demonstrator links a scalable hydrologic ensemble forecasting system with user-specific visualization and analysis in a web-based dashboard. Furthermore, modules for education and training of users in the use of probability-based warnings and forecasts are planned. In doing so, it integrates novel methods of precipitation estimation using commercial microwave links (CMLs) with a radar multisensor calibration and ensemble-based precipitation forecasts to achieve seamless forecasts with shorter update cycles for the short-term range for flash floods. The demonstrator will undergo extensive, multi-stage validation and demonstration to best support iterative, user-driven development. This will be done in close cooperation with the associated partners for different regions in Germany.

The starting point of the proposed project is the joint project HoWa-innovativ "Early flood warning for small catchments with innovative methods of precipitation measurement and prediction". The solutions developed in HoWa-innovativ, the radar CML adjustment and the web-based demonstrator for early flood warning, show the current state of research. However, for a transfer into practice, further progress in research and development has to be achieved, especially in the fields of radar CML adjustment, the prediction of small-scale heavy rain events and flash floods, the robustness of the data flows as well as the user-specific result communication and system validation.
