Abstract
Effect of wave history to the beach profile changes due to longshore sand transport is investigated by the numerical simulation by using the contour line change model. The profile changes and wave climate were investigated on the Shimoni-ikawa coast. Wave history in the model simulation was selected as follows; single wave height, two wave heights (low + high and high + low), and gradually decreasing and increasing wave heights. In each case, beach profile changes were compared with the ones observed on the Shimoni-ikawa coast.Qualitative agreement was obtained.
