【 摘 要 】

The establishment of breakwaters in Japanese ports has progressed in recent years and has greatly improved the calmness in the ports. However, the seawater exchange within and outside of the port has greatly decreased. In ports near urban areas, in particular, the inflow of domestic and industrial wastewater, and the accumulation of sludge are causing a variety of environmental problems. Therefore, it is necessary to solve two contradictory technical problems: improving seawater exchange while at the same time improving calmness in the port. An armored caisson breakwater with intake holes has been developed to conduct external seawater into the port using wave energy. In this paper, the hydraulic characteristics and the practical design of this structure will be presented.
