Abstract
Offshore structures are occasionally located at a relatively deep water region, the outside of breakwater. In this case, these structures may be damaged by the supposition of incident and reflected waves from a vertical breakwater. To prevent the damage, the reflected waves are controlled by installing porous structures at the face of the vertical breakwater. In this study, numerical experiments are carried out to identify the characteristics of wave reflection from the porous structures installing in front of a vertical or slit caisson.

Offshore structures such as oil buoys or floating structures are sometimes required to be located outside of a breakwater
The reflection coefficient decreased as the height of the porous structure increased when the porous structure was installed in front of the vertical caisson or the slit caisson
It was observed that the reflection coefficient decreased as the height of porous structure increased when the porous structure was located in front of the vertical caisson or the slit caisson
Summary
Offshore structures such as oil buoys or floating structures are sometimes required to be located outside of a breakwater These structures may be damaged by the reflected waves from a vertical breakwater as well as incident waves. One possible way to reduce reflected waves is dissipating wave energy by adding porous structures at the face of a vertical breakwater. Few studies regarding numerical experiments have been paying attention to the wave reflection from a vertical breakwater with a frontally porous structure because of complexities of interaction between porous flow and nonlinear waves. Following Sollit and Cross 1 , several researches were carried out on wave and porous structure interaction 2, 3. These studies were less practical because they assumed linear wave, constant depth, or integrated over the depth. CD, the resistance force due to porous media Rx and Rz are defined by the following equations: Rx
