ON THE WAVE ABSORBING CHARACTERISTIC AND THE WATER SUPPLING CHARACTERISTIC OF THE FLOATING BEACH

Abstract

In this research, the “floating beach” which combines the floating breakwater and a pump function was developed. The floating beach is constituted from the board prolonged in the shape of radiation onthe slope of a cone form at equal intervals, the skirt attached at the equipment lower part, and thehose for water supply extended in the lower part. In phenomenon the movement energy of a wave is dissipated by loss of that an incidence wave converges to equipment, and wave breaking and wave overtopping, and the dissipation by the skirt. Moreover, it is equipment which can send water to a lower layer through the hose with which the wave which ascended the inclination board flowed into the hole of the equipment central part, and was extended below by making the grade out of which the top part of the equipment central part comes for a while from the water surface float. This research examined the wave absorbing characteristic at the time of installing a floating beach model in straight line arrangement and alternate arrangement, and the water supply characteristic depended on floating beach.
