潮位変動を考慮した海水交換型防波堤の開発

抄録

Lately, the breakwater where waves not only are controlled but also the water quality is purified has come to be requested. In one of such structures, there is a breakwater with the submerged mound. The offshore seawater rises on the submerged mound the water elevation, and flows into the port through the hole in the breakwater. However, the seawater-exchange function goes down in the area where the change of the tide level is large occasionally.
In this study, we developed the moving structure to tide level change, and examined the hydraulic characteristic. On the floating structure, the seawater rises the water elevation, and the seawaterexchange function does not go down even if the change of the tide level is large.
