Meaning and Definition
The process by which sediment (sand, pebbles) is moved along a coastline by waves that approach the shore at an angle.
A specific coastal geomorphological process responsible for shaping beaches, forming spits, and transporting material alongshore, driven by the prevailing wave direction and swash/backwash action.
Dialectal Variation

- Using 'longshore' as a standalone adjective (e.g., 'longshore currents' is correct, but 'the drift is longshore' is unnatural).
- Confusing it with general erosion or tidal movement.
FAQ
Frequently Asked Questions
No, they are related but distinct. A longshore current is the movement of water parallel to the shore, which is one of the mechanisms that contributes to the transport of sediment known as longshore drift.
It can be impeded or redirected by human-made structures like groynes, breakwaters, or sea walls, but the natural process itself cannot be completely stopped without fundamentally altering wave patterns.
No, it can transport any loose sediment, including pebbles and gravel, although finer sediments like sand are most easily moved.
It is crucial for coastal management, predicting erosion and accretion patterns, designing coastal defences, and understanding the natural formation of features like spits and tombolos.
The process by which sediment (sand, pebbles) is moved along a coastline by waves that approach the shore at an angle.
