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… Web1 de jan. de 2015 · As a result, the longshore current is stronger and toward the south during the southwest monsoon (Narayana et al., 2001). Natural processes such as waves, littoral currents, offshore relief, rainfall, and sea-level changes are responsible for erosion/accretion of the coast and subsequent shoreline changes.
