Urban Flood Risk Mapping of a Coastal Megacity—An Application to Mumbai, India

Major coastal cities across the Globe are at flood risk. This thesis develops an overarching framework for urban flood risk mapping that comprises four interlinked modules of work: design rainfall estimation (input to flood hazard mapping), flood hazard mapping (physical and engineering aspects of risk), vulnerability mapping (social aspects of risk), and flood risk mapping. Demonstrated on Mumbai, it is the first effort for a megacity in India and aims to bridge the gap between various disciplines towards a comprehensive framework for urban flood risk mapping. Moreover, scientific contribution and application of the proposed framework have received equal emphasis.
