Resumen en español

En este artículo se presenta un nuevo enfoque sobre la evaluación de los riesgos de inundación a largo plazo, de acuerdo con el informe sobre predicciones de inundaciones de UK Foresight Future Flooding. Un modelo morfodinámico ha sido desarrollado para simular procesos como el transito de avenidas, el transporte de sedimentos y la evolución correspondiente de los cauces. El modelo se emplea un doble enfoque, con un planteamientorefinado del mojado y secado; usando dos formulas de la velocidad incipiente de vehículos inundados bajo distintos escenarios para comprobar la estabilidad de vehículos en avenidas; y un modelo numérico integrado ha sido desarrollado para predecir avenidas y los riesgos correspondientes a personas (niños y adultos) y de la propiedad (vehículos y edificios).

Abstract

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).

Key words:

Flood, risk, modelling, UK, sediment, pollution
