Any three from:

  • Waves enter an area of shallow water/waves enter a sheltered area, eg a cove or bay
  • There is little wind
  • A river or estuary flows into the sea reducing wave energy
  • There is a good supply of material and the amount of material being transported is greater than the wave energy can transport.

Longshore drift happens when waves approach the beach at an angle. The swash (waves moving up the beach) carries material up and along the beach. The backwash (waves moving back down the beach) carries material back down the beach at right angles. This is the result of gravity. This process slowly moves material along the beach and provides a link between erosion and deposition. The material is transported through suspension, traction, solution and saltation. Longshore drift provides a link between erosion, transportation and deposition.
