WebApr 29, 2008 · The energy released when waves break on the beach creates longshore currents. When waves approach the beach at an angle rather than head on, part of the wave's energy is directed perpendicular to the shore and part of it is directed parallel to the shore. The parallel energy generates the longshore current, which runs along the shoreline. WebLongshore drift is simply the sediment moved by the longshore current. This current and sediment movement occur within the surf zone. The process is also known as littoral drift. …
