This usually occurs in one direction as dictated by the prevailing wind. This current and sediment movement occur within the surf zone. longshore drift may be a signicant component of this, the fact that groynes Introduction. The majority of sediment is transported in the surf zone. What are the three coastal processes that affect coastal areas? 5 minutes. 3. Beach material can be moved in four different ways. For example, the prevailing wind along the Holderness Coast is north-easterly. Longshore drift has constantly been a problem on the Gold Coast. Processes called erosion, mass movement and weathering break down and remove material from the coast. Waves approach the coast at an angle. longshore currents are ocean currents that flow parallel to the coast while beach drift . On the sediment within, and updrift of, the groynes will lead to a decit in the sediment budget which may be reected in either increased erosion of the hinterland, or beach lowering. The angle of the slope steep slopes erode more violently and frequently. It happens when waves approach the beach at an angle. This process slowly moves material along the beach and provides a link between erosion and deposition. Waves erode the coast and transport the eroded material along the coastline. This movement of material is called longshore drift and occurs in a zigzag. along the coastline; Assumption: That pebble long axes decrease in size towards the Landforms created by deposition include beaches, spits, tombolos and bars. Urban and industrial development occupies a small proportion of the catchment (less than 0.7%); minimal expansion has occurred since 2014. 4. These are: Sediment is carried by the waves along the coastline. Give reasons why this should happen. Sediment is moved along the coastline in a process known as longshore drift. As the ocean starts eroding the introduced sand, the water offshore can become muddy, potentially smothering marine life and changing coastal water quality.
