Modeling of tidally-induced hydro-sedimentary processes in the coastal zone of the southern part of the dover strait

The present paper deals with the modelling of hydro-sedimentary processes in the coastal area near Cape Gris-Nez and Cape Blanc-Nez (Dover Strait). The modelling procedure consists in coupling different hydro-sedimentary process models with a high spatial resolution two-dimensional tidal flow model (Nguyen and Ouahsine, 1992). The sediment transport models used include two semi-empirical models based on a dimensionless analysis and energetic concepts (Ackers and White, 1973; Engelund and Hansen, 1967), and a more heuristic cu (concentration times velocity) model (van Rijn, 1984 a; b). All these models are applied to predict instantaneous and tidally-integrated sediment transports in the area under investigation.
