A spit is a feature that is formed through deposition of material at coastlines. 3 Changing Tombolos. Coasts that have not been uplifted for tens of millions of years tend to be relatively straight, and are dominated by depositional features, although deposition is also important on irregular coasts. C: Barrier island Sandbar. Some arches appear to have developed from surge channels, which are created by wave refraction causing the focussing of wave fronts on the side of a headland. This is clearly evident in the Tofino area of Vancouver Island (Figure 17.1), where erosion is the predominant process on the rocky headlands, while depositional processes predominate within the bays. Tombolo is a deposition landform in which an island is attached to the mainland by a narrow piece of land such as a spit or bar.

Berms prevent off-site sedimentation by diverting runoff to a sediment trapping device and can also be used to divert clean water from entering a disturbed area. In this and similar cases like Cadiz, while the strip of beach material connected to the island may be technically called a tombolo because it links the island to the land, it is better thought of in terms of its formation as a spit, because the sand or shingle ridge is parallel rather than at right angles to the coast. Once attached, the island is then known as a tied island. The river and stream water is loaded with sediment that eventually settles out in the ocean.
