【 摘 要 】

Many in situ measurements of hydrodynamic parameters and sediment transport in the surf zone have been carried out on the beaches of the western coast of Normandy. The vertical and cross-shore distributions of the sediment transport induced by breaking waves have been identified in a set of various hydrodynamic conditions. Several longshore sediment transport formulas have been devised. The comparison between measured and computed transport rates enables choice of the best formulation according to the hydrodynamic context. This formulation emphasizes the indirect effect of tidal fluctuations on the wave characteristics and the sediment transport processe.
