Translated title: Climate Resilient Urban Development: Heavy Rain in Large and Medium-Sized German Cities
German cities are increasingly exposed to the risks of heavy precipitation as a result of climate change. The combination of high volumes of precipitation occurring within a short period of time together with particular structural characteristics of cities with a high degree of sealing increasingly leads to flash floods. This has already resulted in high material damage. As a result, there is a considerable pressure to take action in order to better prepare cities for extreme weather events through the help of spatial planning measures.
Under the direction of the University of Potsdam, the project "Urban resilience to extreme weather events - typologies and transfer of adaptation strategies in small cities and medium-sized towns" (short: ExTrass) is investigating and testing innovative approaches to urban planning and risk communication with the aim of increasing the resilience of medium-sized and large towns. The project consists of a consortium with the Leibniz Institute for Spatial Social Research (IRS) and adelphi, as well as Johanniter and the cities of Potsdam, Remscheid, and Würzburg.
