  • Blackpool Sea walls built to stop sea advancing
  • Scarborough
  • Llandudno Concrete groyne Sea wall built to Stop town from flooding
  • 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.
  • 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.
  • Picture of sea wall
  • Area not protected and deemed unworthy of saving.
  • 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.
  • Breakwater
  • Neighbours from hell … (not quite, but equally as annoying)
    • By implementing coastal management methods, you transfer your problem and multiply it for your neighbours further down the coast.
    • Task: With the aid of diagrams, explain how building groynes and breakwaters will cause a problem for others. (Read bottom paragraph – p.68 UG)
