WebJul 7, 2024 · What are the problems with longshore drift? Longshore drift also builds barrier beaches and barrier islands. Barriers are long narrow strips of sand and gravel that are separated from the main shore by lagoons, marshes and mud flats. Sometimes people will build fences or walls to try and slow down longshore drift. What do beach profiles tell you? WebLongshore drift is the process of sediment transportation across a beach. It is dependent on the prevailing wind which affects the waves and as a result the swash (waves up the beach). Sediment is transported with swash at a 45 degree angle up the beach and 90 degree angle back to the sea with backwash.

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.

WebDrift alignments are best developed where waves arrive at an angle of 40°–50° to the coastline. They are typically sinuous in detail, with intermittent lobes and cusps that migrate downdrift, and longshore spits and bars that diverge slightly alongshore. Variations in transverse profile occur as these features pass along the beach.
