- A mumerical model for the calculation of shoreline evolution of a straight beach is developed. In this model, the influence of the change of shoreline orientation during evolution on the change of wave refraction is considered. Using this model, the results of computation of the deposition period on the updrift side of a breakwater agree well with the results by a physical model. In computation of the shoreline erosion on the downdrift side of that breakwater, the influence of the variation of longshore breaker height is considered. This model can be used to predict the shoreline erosion-deposition pattern on both sides of a coastal structure on a sand beach or to evaluate the effective service period and the length of sand trapping structure.
