Hamburg´s heavy rain hazard map is a key tool for public information and raising awareness for flood risks as well as for prevention and emergency measures. It simulates the effects of heavy rainfall for the entire city area. Thus, it indicates where there is a high risk of flooded streets or overflowing cellars in case of heavy rains of varying intensity. VRVis research partner Hamburg Wasser is responsible for this project on behalf of the Ministry for the Environment, Climate, Energy and Agriculture (BUKEA).
The hydrodynamic simulations for the heavy rain hazard map were realized with the flood simulation software of VRVis. It visualizes flood risks for large areas within a very short time while considering complex water structures. VRVis´ research group “Integrated Simulations” has provided ongoing support for the team at Hamburg Wasser during the implementation.
Facilitating climate change adaptation and precautionary measures for the whole city
The heavy rain hazard map for Hamburg considers numerous parameters, such as the shape of the terrain, surface drains, the soil´s infiltration capacity and the capacity of the city's sewage system. It indicates critical areas and enables citizens to take precautions measures on their own. Moreover, it is an important tool for urban planning professionals, who can use it to develop and realize climate adaptation solutions. The heavy rain hazard map can be updated regularly and thus incorporate structural modifications.
