... material--sand, gravel, and cobble fragments--is washed to sea by streams and rivers. Two separate processes result in the deposit of this sand and sediment on the shore. Most sediment is suspended in sea water and transported along the coast by the longshore current, a stream of water flowing parallel to the beach that is created by the action of waves breaking at an angle to shore. Longshore transport can deliver up to a million cubic yards of sediment annually to a single beach. 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 o ...
