Most of fishing ports are located in the surf zone. As a result, channel sedimentation has become a serious problem. As an example, when planning groins to control littoral drift and nearshore current, annual maximum wind waves heights is used as the external forces condition. However, the effect as expected is not obtained in many cases. In this paper, we present relationships long period waves and channel sedimentations from the observation data and numerical simulations on waves and currents.
