Assessment of historical trends and future rainfall conditions

While studying the impacts of extreme finescale rainfall on urban flooding, historical and future trends need to be accounted for. This is done by trend analysis on historical rainfall data and through the analysis of simulation results of climate models. For the latter task on future climate change trend assessment, given the coarse resolution of the climate models, downscaling to the fine scale features of local rainfall is required. This downscaling is based on the features obtained from local, finescale radar rainfall estimation. This was developed by partners from KU Leuven in collaboration with the IWA/IAHR International Working Group on Urban Rainfall (IGUR). Additional information:
