A spit is a feature that is formed through deposition of material at coastlines. [2] Two or more tombolos may form an enclosure (called a lagoon) that can eventually fill with sediment. As sediment is transported along a shore, either it is deposited on beaches, or it creates other depositional features. In this and similar cases like Cdiz, 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.

These waves then bend around the island to the opposite side as they approach. Such areas have been mapped out as lying along fault lines and on islands. The shoreline moves toward the island (or detached breakwater) due to accretion of sand in the lee of the island, where wave energy and longshore drift are reduced and therefore deposition of sand occurs. necta biology This island-like landform is actually attached to the coast by a thin sand bar or spit.

When Sandspit is connected from mainland to island, it is called a tombolo. The wave pattern created by this water movement causes a convergence of longshore drift on the opposite side of the island. When the coastline changes direction, the materials are often deposited. The concept of equilibrium plan form and equilibrium profile has been widely used as an engineering tool in order to design beach nourishment projects. The scope of this paper is to further explore this "equilibrium beach" concept in crenulated bays, as a long-term tool for beach nourishment projects. On a sandy marine beach, the beach face is the area between the low and high tide levels. [SE] How is a tombolo formed a level geography? The components of a typical beach are shown in Figure 17.16.
