Importance of longshore drift
Witryna14 lut 2024 · Longshore drift is the movement of sediments along a coast by waves that approach at an angle to the shore but then the swash recedes directly away from it. The water in a longshore current flows up onto the beach, and then back into the ocean in a “sheet-like” formation. WitrynaAim 2- To Test if Longshore drift is taking place along Deal Beach on the Day of our visit and if so in which direction the Longshore Drift is taking place. Aim 2a. For this aim, we measured the wave angle. To do this, I laid a protractor on the floor, and watched for about 5 minutes in which direction the waves were travelling.

Coastal engineering structures built out into the water from the shore (such as groins) block the natural littoral drift of sand prevailing along most coasts. This deprives beaches of sand and initiates …
WitrynaDue to the coastline being exposed to strong winds and waves from the north east and from across the North Sea waves have relatively long fetch meaning when they reach the coast they have a large amount of energy making them more powerful and so erosive.
