Abstract
Effect of energy dissipation from the viewpoint of the Reynolds number to clear the wave dissipation performanceof the permeable breakwater, was experimentally investigated. And, this experiment was carried out for the wavepressure on the upright seawall that was put behind the absorbing works.
Then, the result was the following. At present, m is the ratio of largest wave pressure as there was the absorbingworks, pm and largest wave pressure as there was without the absorbing works, pm0. And m clearly decrease with therise in the Reynolds number Re and the dimensionless quantity HI/d′. Now the incident wave height HI and therepresentative diameter of void, d′. In addition m is found between 0.23 and 0.93.
