  3. 3. Look at the following pictures of popular coastal destinations in the UK. What do you notice?
  4. 4. Brighton Groynes Longshore Drift in action

  9. 9. How can coasts be managed? <ul><li>There are two reasons why councils spend so much cash on protecting the coastline in certain areas… </li></ul><ul><li>First – To keep the sea out and protect homes and businesses </li></ul><ul><li>Secondly – To keep the beach there to maintain the tourist trade. </li></ul>
  10. 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.

  12. 12. Area not protected and deemed unworthy of saving.
  13. 13. To keep the beach there … <ul><li>Groynes and breakwaters are constructed at right angles to the beach </li></ul><ul><li>These trap sediment and stop longshore drift. </li></ul><ul><li>They also protect the beach from powerful storm waves – stopping erosion of beach material and cliffs. </li></ul>
  14. 14. Breakwater
  15. 15. Neighbours from hell … (not quite, but equally as annoying) <ul><li>By implementing coastal management methods, you transfer your problem and multiply it for your neighbours further down the coast. </li></ul><ul><li>Task: With the aid of diagrams, explain how building groynes and breakwaters will cause a problem for others. (Read bottom paragraph – p.68 UG) </li></ul>
