Keywords: | basin control; ensemble forecast; flood warning; online simulation; operational warning system | Issue Date: | Jul-2019 | Publisher: | Graie, Groupe de Recherche, Animation technique et Information sur l'eau, Campus LyonTech La Doua | Source: | NOVATECH (2019-07) | Abstract (english): | Sophisticated strategies are required for flood warning in urban areas regarding convective heavy rainfall events. 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. |
