Title: | Optimisation of rainfall-runoff modelling for urban flood management with ensemble radar nowcasts | Language: | English | Authors: | Hellmers, Sandra ![]() Strehz, Alexander Leese, Nina Sophie Einfalt, Thomas Fröhle, Peter |
Keywords: | Ensembles; Radar Data; Rainfall Runoff Modelling; Urban Flood Management | Issue Date: | 2016 | Abstract (english): | Especially in urban areas, improved strategies are required to assess the influence of small scale precipitation patterns of local heavy rainfall events in a flood warning context. The results of the case study show a wide range of possible precipitation scenarios given by the radar nowcast ensemble members for a local rainfall event. This reflects the large uncertainty in predicting discharge curves. The first steps of the project StucK (2015 till 2018) are presented here: (1) developing a methodology to compute ensemble nowcasts of local heavy rainfall events, (2) integration of small scale radar rainfall nowcasts in a Rainfall-Runoff Model and (3) first approach with percentiles to optimize the Flood Warning Service Hamburg. Within the project different statistical approaches will be analysed to improve the online forecast system. |
