It developed the “floating beach” which has the floating breakwater and a pump feature in this research. The floating beach is composed of the convergence embankment which was radially spread from the center to the regular intervals to the cone slope, the skirt which was installed in the equipment lower part and hose for the flow of water which was stretched from the hole of the apex to the lower part. Experimentally this time, there is a hose to attenuate in the side of the equipment in the wave energy among floating bodies. Also, the wavewhich did an inclination board in the going againt stream because a few apexes of the equipment central part went out of the surface of the water flows in to the hole on the equipment center and is the equipment the flow of water of which to the substratum is possible with the stretched hose in the lower part. That is, it is equipment with flow of water using the change operation on the potential energy of water from the kinetic energy of the wave. This research sought that the wave attenuated in which degree by the value with period and wave height aboutthe case to have arranged the floating body in one line and the case to have arranged at the plover from the experiment. Moreover, when making the wave overtopping head of the floating body constant, it sought flow of water quantity by the value with period and wave height.
