Abstract
The results of experimental investigation for the hydraulic characteristics of the seawater exchange caisson breakwater with Y-shaped perforated walls are presented. Laboratory experiments were carried out in a wave flume for regular and irregular waves of different wave heights and periods by changing two kinds of the caisson geometry, the chamber with and the screen height of the perforated wall. The wave reflection became minimum when B/Lc0.1 regardless of the chamber width, contrary to the results of conventional caisson breakwater, B/Lc0.2. The reason of such difference was ascribed to the difference in the thickness of the perforated front wall, which implies that the most efficient frequency for dissipating wave energy can be controlled by adjusting the thickness of the perforated wall. The seawater intake volume was maximized when the screen height was located at the mean water level. In this condition, the effects of the chamber width to the characteristics of seawater intake were insignificant. It was also found that the normalized mean net inflow velocity has a linear relationship with the reflection and transmission coefficients for irregular waves.
