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…

WebDrift alignments are best developed where waves arrive at an angle of 40°–50° to the coastline. They are typically sinuous in detail, with intermittent lobes and cusps that migrate downdrift, and longshore spits and bars that diverge slightly alongshore. Variations in transverse profile occur as these features pass along the beach.

WebGroyne. A groyne (in the U.S. groin) is a rigid hydraulic structure built perpendicularly from an ocean shore (in coastal engineering) or a river bank, interrupting water flow and limiting the movement of sediment. It is usually made out of wood, concrete, or stone. In the ocean, groynes create beaches, prevent beach erosion caused by longshore ...

WebLongshore drift has a very powerful influence on the shape and composition of the coastline.
