Hydrodynamic modelling to support enhanced flood risk estimation

This paper presents a new approach to long-term flood risk assessment in accordance with the UK Foresight Future Flooding Report. A morphodynamic model has been developed to simulate the processes of flood routing, sediment transport and corresponding bed evolution using a coupled approach, with a refined wetting and drying approach being used; two incipient velocity formulae for flooded vehicles under different scenarios were proposed for assessing stability criteria of vehicles in floodwaters; and an integrated numerical model was developed to predict the inundation of flash floods and the corresponding flood hazards to people (children and adults) and property (vehicles and buildings)
