実海域を想定した港内水排出式海水交換防波堤の効果に関する模擬港湾実験

Sea water pollution in a fishery harbor is one of serious problems in fishery industries. Safety of sea foods is heavily dependent upon the quality of sea water in a harbor and its neighboring sea area. On the other hand, since a fishery harbor is a base for fishing boats and vessels, the tranquility of a harbor basin must be securely controlled by the surrounding breakwater system. In order to solve the above mentioned contradictory problems of the fishery harbor, we have proposed and developed a new type of sea water exchange breakwater, which has a wave control function as well as water exchange function. In this study, performance of the newly developed water exchange breakwater in the model harbor basin was examined extensively, such as a water exchange function and wave sheltering effect for various water-exchange breakwater allocations. It was confirmed that five water exchange breakwaters were sufficient to exchange sea water in the model basin for given nominal wave conditions.
