Modelling flood hydraulics and overbank deposition on river floodplains

Auteur(s) et Affiliation(s)



Description :
This paper outlines a numerical model for the prediction of floodplain inundation sequences, overbank deposition rates and deposit grain size distributions. This model has 2 main components: first, a simplified hydraulic scheme which predicts floodwater flow depths and velocities, and second, a sediment transport element which employs a mass balance relation describing suspended sediment dispersion by convective and diffusive processes and sediment deposition as a function of particle settling rates. The model is applied to a 600 m reach of the River Culm, Devon, U.K.
