In the second process, sand deposited onshore by the longshore current is then oscillated by waves breaking onto and receding from the beach. This continual onshore-offshore movement gradually pushes the sand along the beach edge. both the longshore transport of sediment along the coast and the movement of sand by waves along the foresh ....
