How does longshore drift work
WebJan 1, 2024 · Longshore drift is caused by wave and current action. It is the primary method of sediment transport along the beach. The direction of this motion is always parallel to the beach face. On Folly Beach, as well as other islands along the southeastern coast, the lonshore drift most often moves in a north to south direction. WebThe side of the groyne facing the longshore drift blocks the movement of sediment and it is deposited. The side protected from the waves is starved of sediment because waves cannot reach it to deposit load. Consequently there can be a considerable difference in the height of the beach on either side of the groyne.

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… WebDue to their perpendicular-to-shore placement, jetties can disturb the longshore drift (sediment transport) and cause downdrift erosion. The longer the jetty is, the greater impact it has on adjacent areas. Seawalls often interfere with natural processes such as habitat migration, causing the impairment of intertidal habitats.
