The sealing of surfaces and changes in land use as a result of population developments, as well as an ageing infrastructure, present new challenges for urban water management. Changes in catchment areas are mirrored by changed flood risks, even in areas not previously affected. A comprehensive analysis of scenarios is indispensable in achieving forward-thinking planning and adapting existing water infrastructures to better reflect current changes and the dynamics of the urban setting. Not only are urban areas themselves constantly changing; climate-related changes can significantly influence urban water infrastructures. In this regard, torrential rains that only impact small areas are especially important.
The results of analyses confirm the necessity of taking into account multiple urban development scenarios, in combination with climate change prognoses, in order to accurately determine the risks for potentially problematic areas in the network.
