ABSTRACT:
Waves are amplified by a gradual decrease in depth, and when the waves reach a vertical wall10of a reef2, breaking waves are generated by sudden decrease of the water depth. As the breaking waves rush into the upper portion of the reef2and pass through the slant slits14, wave energy is absorbed by the reef2and the seat water returns back to the ocean through an opening11. The sand brought into a reef2with the waves are washed away by the return flow11so that the sand is not deposited within the reef2and the space in the reef2is always clear.The return flow promotes generation of the breaking waves. The breaking waves are introduced into the slits, beach erosion is prevented, and a calm sea area utilized for marine leisure is created. The seawater in the reef, with sufficient air, flows to the sea area behind the breakwater through the paths19. The sea water containing sufficient oxygen is supplied to the bottom layer behind the breakwater without disturbing the surface so that the oxygen is supplied to the seawater behind the breakwater.
