Longshore Drift (littoral drift) Longshore drift is a process responsible for moving significant amounts of sediment along the coast. This usually occurs in one direction as dictated by the prevailing wind. For example, the prevailing wind along the Holderness Coast is north-easterly.
Longshore Drift littoral drift Longshore drift is a process responsible for moving significant amounts of sediment along the coast. Notice how the swash moves up the beach at an oblique angle then the backwash retreats at a right angle to the coast.Longshore drift can form spits were the line of the coast changes sharply, for example at a river estuary. There are several examples of spits along the Welsh coastline. This clip is from.When longshore drift transports material along the coast, it sometimes comes across an estuary or a change in the direction of the coastline. In either case, the transport process tends to carry on moving the material in the same direction. Over time, a ridge of material will build up into the deeper water. This will form a spit. Eventually the spit may form a substantial feature, many miles.
Transportation. Beach material can be moved in four different ways. These are: Solution - when minerals in rocks like chalk and limestone are dissolved in sea water and then carried in solution.
Longshore drift here has the potential to drag away the town’s beach and as such a new combination of management including rock and wooden groynes has been installed since 2006. Accumulations of sand either side of these groynes show the success of the groynes, so too does the width of the beach along a transect of the seafront.
Longshore drift transports material along the length of the Holderness Coast. Attrition and abrasion erosion makes the pebbles rounder and smaller as it travels through its journey from west to east. Firstly we measured the angle of the facet using the clinometers but we had to calibrate the clinometer.
Longshore drift along the Sussex and Kent coast is usually from west to east because most of the coast is exposed to storm winds and waves advancing up the Channel from the west or south-west. As a result of this longshore drift, shingle tends to accumulate on the west side of groynes and harbour arms.

Longshore Drift Longshore drift happens when waves approach the beach at an angle which results in the gradual zig-zag movement of beach materials along the coast. Waves approach the beach at an angle because of the direction of the prevailing wind and the fetch. Beach materials are sand, gravel, shell fragments and pebbles.
Longshore drift refers to the movement (or transportation) of sediment along a coastline, by the waves. The prevailing wind determines the angle at which the swash (the waves which move up onto the beach) comes in.The backwash (the waves coming down off of the beach) will come down in a straight line.This creates a zig-zagging effect as the swash comes in at an angle and the backwash comes.
Longshore drift is a natural process occurring as waves wash onto beaches. insert diagramThe waves are washed onto the beach at an angle, so the 'swash' occurs diagonally.As the water recedes back into the sea it drags the sand etc in the 'backwash' in a straight line.
The Holderness Coast is a great case study to use when examining coastal processes and the features associated with them. This is around 2 million tonnes of material every year. Beaches along the coast comprise mainly of shingle and sand eroded from the clay till. Spurn Point provides evidence of longshore drift on the Holderness Coast.
Beach Drift and Swash. The longshore current is part of the longshore transport that moves sand and sediment down the coastline, but there is also another process that contributes to the longshore.
