Modélisation des mises en suspension dans le détroit du Pas-de-Calais sous l’influence des courants de marée et de la houle.
Résumé
A three-dimensionnal model based on COHERENS [Luyten et al., 1999] is used to simulate the suspended sediment transport in the Dover Straits and its coastal adjacent areas. The model reproduces measurements of current, turbulence and concentration at two shallow water sites off Hardelot and Merlimont beaches. The pattern of sediment resuspension is presented on a mean tide cycle. The influence of surface gravity waves is investigated with the use of a spectral wave propagation model and a model of wave-current interaction in the bottom boundary layer.
