Seawater exchange breakwaters may be useful to keep the water quality and also to maintain the seabed condition in a harbor. We have already presented a new type of seawater exchange breakwater, which is able to induce outgoing mean current to the offshore by the wave excited vortex motion in the breakwater. In this study, we examine the effectiveness of the breakwater in harbors, such as wave sheltering effects and water exchange abilities. Two ifferent harbor models are adopted to test the effectiveness of the breakwater. Performance of the breakwater in the harbor is also compared to the previous two dimensional results in the vertical plane. It is seen that the new breakwater is effective in harbors in the same way as the two dimensional wave field.
