WAVE FORCES ON VERTICAL BREAKWATER ON REEF COASTS

Eizo Nakaza, Seikoh Tsukayama, Mikio Hino

Abstract


The characteristics of the 'Bore-like surf beat", one of long wave phenomena occurred on the reef coasts, are clarified by the field observations and experiments. And also, wave forces on breakwaters in the reef coasts are verified through the experiments. A new pressure formula, taking into account of the wave force due to " Bore-1ike (Tsunami - 1ike) surf beat", is suggested, and it is shown that the calculations by the formula show good agreement with results of experiments.
