Longshore currents develop when waves approach a beach at an angle (Figure 12.37). Longshore currents cause sediment transport called longshore drift.

WebLongshore transport moves sediment in a zigzag path. Longshore transport can change direction depending on which direction the waves approach the beach. Longshore transport moves sediment upcoast or downcoast along the beach. A summer recreational beach typically has more sediment on it than a winter recreational beach. WebThis process of longshore transport is responsible for moving sediment up and down coastlines. It can sometimes lead to the development of barrier islands and spits—thin strips of beach that generally form parallel to the mainland. Before 1933, a single barrier stretched along the eastern seaboard of the Delmarva Peninsula in the United States.

WebThe movement of the material is known as longshore drift. Waves approach the coast at an angle because of the direction of prevailing wind. The swash will carry the material … Longshore drift from longshore current is a geological process that consists of the transportation of sediments (clay, silt, pebbles, sand, shingle) along a coast parallel to the shoreline, which is dependent on the angle incoming wave direction. Oblique incoming wind squeezes water along the coast, and so generates a water current which moves parallel to the coast. Longshore drift i…
