Abstract :
A numerical beach evolution model, which can predict depth contour line change due to beach nourishment, was proposed. The effect of beach nourishment was taken into account by solving two- dimensional advection diffusion equation for nourished sand material. Some model tests of beach evolution due to nourishment were performed. Furthermore, the new N-line model was applied to preservation of eroded beach using a sand recycle method measures, and then the performance of the model was investigated.
