【 摘 要 】

A study of hydrodynamics and multicomponent sedimentary processes associated to unbroken water waves propagating in coastal areas is presented. For the specific case in which the waves are normally incident, weakly non-linear and dispersive, and the foreshore profile displayed a gentle slope, a model of wave-induced heterogeneous sand transport and resulting topographical and granulometric changes is developed. The general conclusion of this study is that the model presented describes some of the observed features of the sedimentology of longshore bars systems.
