How does longshore drift work
Longshore drift from longshore current is a geological process that consists of the transportation of sediments (clay, silt, pebbles, sand, shingle) along a coast parallel to the shoreline, which is dependent on the angle incoming wave direction. Oblique incoming wind squeezes water along the coast, and so generates a water current which moves parallel to the coast. Longshore drift i… WebYou could also measure longshore drift by recording the distance the float travels over a set period of time e.g. 5 minutes. When measuring longshore drift you should also consider …

WebIt is formed due to longshore drift transporting sediment along the coastline. Behind the bar, a lagoon is created, where water has been trapped and the lagoon may gradually be infilled as a salt marsh develops due to it being a low energy zone, which encourages deposition.
