Longshore Drift
The transport of sand and pebbles along the coast is called longshore drift. -
Longshore drift: Coastal processes on the Gold Coast
Sand is moved by wind and currents, which are created by wave or tidal energy. -
Longshore Drift (littoral drift)
Longshore drift is a process responsible for moving significant amounts of sediment along the coast.

Coastal Deposition
-
Landforms of deposition
Landforms of deposition occur where accumulation of sand and shingle is greater than it is removed.
-
Coastal Deposition
Where sand/shingle is deposited on a beach rather than removed - inputs are greater than outputs.

Features of Coastal Deposition
-
Features of coastal deposition
Depositional features produced by longshore drift include spits, bars and tombolos.
-
Features of Deposition
In a coastal environment, deposition results in the accumulation of sediment along or near a coastline.
-
Coastal deposition features
Created by constructive waves depositing material (sand, shingle and pebbles) that has been transported from further along the coast.
