Importance of the swash longshore sediment transport in morphodynamic models
Importance du transport solide par jet de rive dans les modèles morphodynamiques
Résumé
This paper discusses the effect of the longshore sediment transport in the swash zone on the evolution of the shore line. The beach evolution model presented here is based on an N-line approach including a local estimation of the sediment transport function of the local current and wave characteristics. A simple model for the longshore sediment transport in the swash zone is implemented to the beach evolution model. The erosion and the accumulation of sediments around a groin appear to be significantly influenced by the introduction of the swash sediment transport.
