Only Some Parts of the Coast are Defended


  • Protect homes.
  • Protect businesses.
  • Protect the environment from erosion & flooding.


  • Flooding and erosion of the coastline can have severe social, economic and environmental impacts.
  • All coastal settlements want to be defended, but the amount of money availableis limited so not everywhere can be defended.


Four Options for Coastal Management

  • Hold the line- maintain the existing coastal defences.
  • Advance the line- build new defences.
  • Do nothing- build no defences and deal with erosion and flooding as it happens.
  • Managed realignment – allow the shoreline to move but manage retreat so it causes least damage.
