Web6 de jun. de 2024 · A longshore current is a current that flows parallel to the shore within the zone of breaking waves. Longshore drift is the movement of sediments along a coast by waves that approach at an angle to the shore but then the swash recedes directly away from it. How do currents affect coasts? WebThe most widely used formula for longshore transport (LT) is the CERC equation (Shore Protection Manual, US Army Corps of Engineers, 1984).
