WebNov 28, 2024 · How does longshore drift create spits? Longshore drift moves material along the coastline. A spit forms when the material is deposited. Over time, the spit grows and develops a hook if wind direction changes further out. Waves cannot get past a spit, which creates a sheltered area where silt is deposited and mud flats or salt marshes form. WebSpits are formed when longshore drift travels past a point (e.g. river mouth or re-entrant) where the dominant drift direction and shoreline do not veer in the same direction. [6] As well as dominant drift direction, spits are affected by the strength of wave-driven current, wave angle and the height of incoming waves. [7]
WebJan 1, 2024 · The configuration of the spit terminus depends mainly on (1) the longshore sediment transport rate; (2) wave diffraction and refraction processes; and (3) the interaction between dominant waves and waves arriving from … WebJul 26, 2011 · Spits are formed as a result of littoral drifts traveling past the entrant point of a body of water, such as a river’s mouth or river’s entrant. Spits have two important features. On one end, the spit is attached to the land while the other end that is out into the sea resembles a hook shape due to varying wave directions.
