Urban Flood Resilience - A case study on how to integrate flood resilience in urban planning.

Abstract: Climate change and increasing urbanization gives societies great challenges in managing urban planning for a sustainable future. Urbanization aggravates floods by increasing the amount of impermeable surfaces and by modifying flow routes. Resilience is the capability to recover from a stress and high resilience is seen as the goal of a healthy development. By including the concept of resilience in flood risk analysis and decision making, flood control will be more complete and intrinsically more sustainable. This project investigates how flood resilience can be modeled in a way that allows spatialization. An index called Spatialized urban Flood RESilience Index, S-FRESI, was built and tested with promising results. It can be used to measure and visualize the changes in flood resilience obtained by flood control measures. The index show areas that are particularly vulnerable to flood hazards and where suggested flood measures enhances the resilience.
