In the design of breakwater layout of the harbor, the first priority must be given to maintain tranquility. At the same time, we have to pay attention to keep the water quality in the harbor. We have investigated the functions of breakwaters with channel to exchange water in harbors.
In this study, we examined the performance of the breakwater layout and the breakwater with channel in small harbor to maintain tranquility and exchange water in the obliquely incident wave and tidal current. In a three-dimensional wave basin we examined the several cases of the breakwater layout in the model harbor, that is, the width, shape of the entrance, water area in harbor, and so on. We also examined the possibility for predicting waves in harbors of various shape numerically by using experimental results.
