  • 9. How can coasts be managed?
    • There are two reasons why councils spend so much cash on protecting the coastline in certain areas…
    • First – To keep the sea out and protect homes and businesses
    • Secondly – To keep the beach there to maintain the tourist trade.
  • 10. To keep the sea out ….. Build a sea wall to deflect the power of the waves away from the seafront. However - Lots of maintenance needed and they are expensive to build. The Catch - Councils will only pay for them if there are many people and much property to defend.
  • 11. Picture of sea wall
  • 12. Area not protected and deemed unworthy of saving.
  • 13. To keep the beach there …
    • Groynes and breakwaters are constructed at right angles to the beach
    • These trap sediment and stop longshore drift.
    • They also protect the beach from powerful storm waves – stopping erosion of beach material and cliffs.
