B: Sea arch Eventually, when enough sediment has built up, the beach shoreline, known as a spit, will connect with an island and form a tombolo. Eroded coastlines are defined by wave energy erosion exceeding sediment deposition. In quiet water areas, such as bays, wave energy is dispersed, so A tombolo is formed when a spit connects the mainland coast to an island. In landscaping, berms are commonly used to direct rain away from flat or vulnerable areas. Save. Giant walls that span entire coastlines and attempt to reduce erosion and prevent flooding in the process. The process of longshore drift occurs and this moves material along the coastline. The drift occurs due to waves meeting the beach at an oblique . Elevated wave-cut platforms in southern California are evidence that this coastal area is an emerging shoreline. Make sure to remember your password. The combination of wave refraction, longshore current and beach drift result in a number of different shoreline erosional and depositional features. Spit (landform) A spit contrasted with other coastal landforms. Transported sand will eventually be deposited on beaches, spits, or barrier islands. Shore Platform. Wave Cut cliff- Erosiona.
