Ocean currents and storm waves.

- Ocean currents (including longshore currents) transport sediment away from beaches, causing erosion.
- Storm waves remove large amounts of sand rapidly, accelerating beach erosion.

Dune vegetation stabilizes sand (reduces erosion); shifting shorelines are an effect, and sandbars usually reduce wave energy and can protect the beach.
