Recently, it has been necessary the purification of basin water in port and harbor for utilizations, such as live fish preservation facilities and amenity space. Therefore, various types of water-exchange breakwater by wave energy, tidal current and sea level exchange have been developed. The authorsdeveloped a wave dissipating caisson breakwater having a function of seawater exchange. This caissonis a permeable slit caisson with a submerged vertical plate in a water chamber, and generates a one-way flow from offshore to harbor.
In this paper, through the field investigation, we proved the water inlet ability of this water-exchange breakwater that was constructed in MISAKI fishing port, and compared the result of the hydraulic model test with the result of the field investigation.
