Europe - Nice, Strasbourg, Odense and Vienna Urban Pluvial Flooding High Resolution - DTU

The data set comprises 208 independent flood hazard maps, i.e. 52 maps for each of the four cities. The data shows the impacts of urban flooding (inundation depth) as a result of high-intensity precipitation corresponding to 10, 20, 50 and 100-year return periods under present-day climatic conditions and for two climate projections, i.e. the Representative Concentration Pathways (RCP) 4.5 and RCP 8.5. To address the uncertainty related to the climate change projections of high-intensity precipitation, Change Factors (CFs) (Table 1) for high-intensity precipitation are calculated based on, respectively, the 10th (low), 50th (median) and 90% (high) percentiles of a climate model ensemble comprised by 10 regional climate model projections from the CORDEX repository.
