OCEAN WAVE CONTROL AND RENEWAL OF SEAWATER BY MEANS OF SUBMERGED HORIZONTAL PLATES

The authors have developed a new floating type breakwater. This breakwater consists of a submerged horizontal plate supported by small floating bodies and slide piles. The slide piles can freely follow the floating part to a sea level irrespective of the tide. In addition, it can increase the damping force to decrease the heaving motion of the floating body in waves. This paper presents detailed results from the extensive experiments. These experiments were carried out to obtain basic data, such as the breakwater performance, hydrodynamic forces on the plate and the influence on the environmental condition behind the breakwater. Through the experiments, it was found that violent breaking waves have occurred on the submerged horizontal plate. It is demonstrated that the breaking waves have an effect on reducing the transmission wave height and to generating the steady flow behind the breakwater. Finally the data for the design of both the dimensions and the structure of the breakwater are given.
