Abstract

Three models including the wave model, the sediment transport model and the bottom evolution model are combined to simulate the bottom change under the action of cross-shore waves. two applications for the combined model are carried. The first application is to simulate the movement and deformation of a sand bar under the action of waves. The second one is to predict the profile change of a model beach with the real size in laboratory. The experimental data and model results are compared to evaluate the accuracy of the model prediction.
