The movement of beach material along a beach in the same direction as the prevailing wind. This process leads to the creation of depositional landforms such as spits and tombolos. transportation deposition swash backwash Back to Resources Associated words
Movement of (beach) sediments approximately parallel to the coastline.
The movement of sediment along a coastline caused by waves striking the coast at an oblique angle. The waves wash sediment particles up the beach at an oblique angle and the swash back to the sea carries the particles down the gradient of the beach. This produces a zig-zag path of particle movement along the beach.
1. The process by which a current moves sediments along a surf zone. 2. The sediments so moved. Longshore drift typically consists of sand, gravel, shell fragments, and pebbles. See also beach drift.
The process in which sediment is moved in a zigzag pattern along a beach by wash and backwash of waves approaching the shore obliquely.
The movement and deposition of coastal sediments because of longshore currents.
The movement of sediment along a beach by swash and backwash of waves that approach the shore obliquely.
The northwards movement of sand along the east coast Australia
the movement of beach sediment along the shore.
lateral movement of sediment in the nearshore zone as a result of wave-induced currents
The build up of river borne sediment along a coastline.
Movement of sediments approximately parallel to the shore
the result of waves approaching a beach at an angle, causing sediments to be thrown up the beach at the same angle. When wave water runs back down the beach (backwash) it tends to drag sediment straight down the beach (by gravity selecting the steepest route). Thus, after one wave cycle a quantity of sediment at the shoreline has moved along the beach by a several tens of centimetres, or several metres with bigger waves.
In geography, longshore drift (LSD) (shore drift or littoral drift) is a process by which sediments move along a beach shore.
