How do longshore currents form

WebAnswwer 9 Longshore currents form when waves approach the shore at an angle, causing the water and sediment to move along the shoreline parallel to the beach. This occurs because waves refract, or bend, as they approach the coast, and their energy is focused on the shoreline at an angle. WebIt develops in places where re-entrance occurs, such as at a cove's headlands, by the process of longshore drift by longshore currents. The drift occurs due to waves meeting the beach at an oblique angle, moving …

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. …
