All of these structures (beach nourishment, groin, and seawall) are designed to prevent or retard shoreline erosion. Beach nourishment involves adding sand or sediment to the beach to widen and strengthen it. A groin is a structure that extends perpendicular to the shoreline and is designed to trap sand to widen the beach. A seawall is a structure built along the shore to protect land from erosion caused by waves and storm surges. Therefore, all of these structures can help prevent or retard shoreline erosion.
