The subproject 3 (SP3) of the research unit SPATE (Space-time Dynamics of Extreme Floods) started in September 2017 at the GeoForschungsZentrum Potsdam of the Helmholtz Association. The overarching goal of SP3 is to achieve a better understanding of causes for the occurrence of extreme floods in comparison to small and medium floods. A comprehensive analysis on the main factors and whose interactions controlling the probability of extreme floods is conducted. Scientific exchange with other researchers of SPATE as well as international scientists is achieved by working in research clusters, focusing on event scale and spatial and temporal variability in this subproject.
