LONG PERIODIC WAVE HEIGHT REDUCING STRUCTURE AND LONG PERIODIC WAVE HEIGHT REDUCING CONSTRUCTION METHOD IN PORT USING THE SAME

摘要

PPROBLEM TO BE SOLVED: To reduce the wave height of a long periodic wave, by arranging this structure at the sea bottom where the long periodic wave flows in and out. PSOLUTION: A digging-in installation type water permeable wave dissipating structure 10 having a top end surface having the height in the same height as or lower than a water bed or a submerged breakwater type water permeable wave dissipating structure 10A banked up higher than the water bed, is arranged on the water bed 11 of a long periodic wave approaching passage outside of the mouth of a bay, in the mouth of the bay or in the bay of a port.
