I found this, mabey it will help; Breakwaters are barriers built offshore to protect part of the shoreline. They act as a barrier to waves, preventing erosion and allowing the beach to grow. The dissipation of wave energy allows material carried by longshore currents to be deposited behind the breakwater. This protects the shore.
