An approach is presented to improve short-term precipitation forecasts by combining ensembles of radar nowcasts with the numerical weather predictions COSMO-DE-EPS of the German Weather Service. The combined ensemble forecasts are produced operationally every 5 min. Applications involve the Flood Warning Service Hamburg (WaBiHa) and real-time hydrological simulations with the model KalypsoHydrology. Ensemble forecast flood hydrographs for the urban catchment Kollau are presented in this work. The range and quantiles are illustrated for a convective storm event in summer 2016. A flood management measure is improved by using precipitation forecasts in a flood control reservoir.enhttp://rightsstatements.org/vocab/InC/1.0/basin controlensemble forecastflood warningonline simulationoperational warning systemIngenieurwissenschaftenConference Paper10.15480/882.3455http://www.novatech.graie.org/documents/auteurs/2B52-158EIN.pdf10.15480/882.3455Conference Paper
