  • Longshore drift
    The zigzag movement of sediment along the coastline. 
  • What is longshore drift 
    • The transportation of the material/sediment by waves is known as longshore drift. 
    • Waves approach the coast at a 45 degree angle because of the direction of the prevailing (most common) wind. 
    • The swash will carry the material towards the beach at this same angle. 
    • The backwash then flows back to the sea, down the slope of the beach.
    • The process repeats itself along the coast in the zig-zag movement
  • Deposition
    When material being transported by the sea is dropped due to a loss in energy.
