Urban water bodies are exposed to multiple stressors due to their intense use. The Stormwater and Surface Water group investigates the effects of material inputs from urban runoff on aquatic ecology. Rainwater runoff from sealed surfaces plays an important role here, as it can lead to combined sewer overflows and transports pollutants from buildings and roads. However, rainwater can also simultaneously have a positive effect via the preservation of small water bodies. Green, blue, and grey elements of sponge cities can help reduce water pollution and offer further benefits, such as increased life quality in cities.
Our extensive experience lies in the monitoring, data analysis, and modelling of rainwater related emissions and their impact on urban water bodies. We also investigate the benefits of rainwater management planning. We bring both areas together by supporting urban strategies or providing digital planning tools.
