Abstract
In this study, the hydraulic experiment results of the slit caisson breakwater with embedded channels are analyzed comparing with the numerical results. To improve the calmness of a harbor area and wave force acting on the breakwater, the energy dissipation mechanism using the cylinder array was applied to the breakwater. This effect is supported by resonance flow in the embedded channel which can be controlled by the design of the channel. In order to evaluate the wave energy dissipation, the reflection coefficient is used to representing parameter. When the wave period and the natural period of the fluid in the embedded channel were matched with each other,reduction of the reflected waves became maximum. In the hydraulic experiment results, its optimum wave condition and reduction of the reflected waves were more expanded than the numerical.nergy dissipation mechanism using the cylinder array was applied to the breakwater.
