WebSpits occur when there is a change in the shape of the landscape or there is a river mouth or estuary. This is how spits are formed: Sediment is carried by longshore drift . 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.

WebLongshore currents are generated when a "train" of waves reach the coastline and release bursts of energy. The speed at which waves approach the shore depends on sea floor and shoreline features and the depth of … WebLongshore currents can carry beach material offshore. This process can produce landforms in open water. These landforms include sandbars, barrier spits, and barrier islands. A sandbar is a ridge of sand, gravel, or broken shells that is found in open water. Sandbars may be completely under water or they may stick up above the water.
