1. Coastal Environments How the coast is eroded Landforms of coastal erosion Transport and deposition of material Coastal management issues Sustainable development of coastal environments  Case study: The Yorkshire coastline: Scarborough

2. Learning objectives: To understand transport and deposition of material along the coast. The process of longshore drift The formation of beaches The formation of a spit

3. Constructive waves Long wave in relation to their height Swash is stronger than backswash Less frequent wave (6-9 per min)

4. High wave in proportion to length Backwash is much stronger than swash Frequent waves Tall breaker. Breaks down with great force Destructive waves

5. Longshore drift

7. Definition of a beach… The gently sloping area of land between high and low water marks

8. Definition of a spit… A long narrow ridge of sand or shingle attached to the land which extend out into the sea.
