CROSS-SHORE TRANSPORT DURING STORM SURGES

[摘要] In order to predict the amount of dune erosion due to a storm surge, a model for cross-shore transport during storm surges has been developed. During a storm with intensive wave breaking, suspended sediment transport is predominant. In the model the nett local transport is computed from the time averaged sediment concentration and the time averaged (secundary) flow profiles. Both profiles are related to the local hydraulic conditions. Finally the computed erosion profile development and the amount of dune erosion are well predicted by the model.
