Figure C5 summarizes velocities for a specific test condition for the base condition and three breakwater plans. Figure C6 illustrates the shoreline response and the currents for a beachfill test of one of the plans. Testing indicated that a 107-m spacing between 46-m-long segments produced satisfactory results within the reach covering the groin field. It was best to place the breakwaters so C4.
