Attribution of flood risk in urban areas

This paper presents an original methodology for flood risk attribution by combining statistical approach with the deterministic modelling and depth-damage curves, and its application to a case study involving integrated analysis of pluvial/fluvial flooding. This enables the assessment of the influence of both the input variables (e.g. rainfall) and system parameters (e.g. pipe diameters) on flood risk, which is an important step forward because previously used methods of attributing risk were based on simpler and more uncertain methods. This work has influenced research publications in several areas: joint rainfall/tidal impacts, climate change adaptation, flood damage assessment and uncertainty propagation.
