The Countermeasure on Wave Overtopping in Water·fron

Abstract

Recently, waterfront developments have been noticed, and it has become important to develop a countermeasure on wave overtopping.
In this paper, next two points are investigated.
(1) Applicable methods to estimate the wave run-up height and the rate of wave overtopping.
(2) Appropriate methods to evaluate the effect of wave dissipation by typical structures. And the following conclusions are obtained.
(1) It is possible to apply the equation proposed by Yamamoto to the calculation of the wave run-up height.
(2) The method by Yamamoto and Horikawa can be applied to the calculation of the rate of wave overtopping.
(3) The experiments indicate that the vertical revetment of energy dissipating blocks has a considerable effect on reducing the rate of wave overtopping.
