How does wave refraction affect the coastline
Did you know?
WebWave refraction refers to what happens to waves when they approach an uneven coastline. Very few coastlines are perfectly straight, and few sea beds have uniform height and shape. This is known as the varying Geomorphology of our coastline and it will affect the waves travelling above it and towards it in differing ways. WebWave refraction and currents cause the wave’s energy to disperse, which leads to deposition forming on the seabed. Over time, the amount of sediment deposited is exposed, extending the beach into the sea as a spit. Three factors determine the length of a spit: secondary currents causing erosion, the flow of a river, and wave action.
WebWave refraction involves waves breaking onto an irregularly shaped coastline, e.g. a headland separated by two bays. Waves drag in the shallow water approaching a headland so the wave becomes high, steep and … WebFeb 20, 2014 · The waves bend the most when they're nearly parallel to the coastline, and don't bend when they're perpendicular to the coast.
