• The main aims of coastal management include protecting people from natural hazards such as flooding or erosion, conserving habitats and wildlife, maintaining recreational opportunities and preserving cultural heritage sites.
• How does a sea wall work?

  Reflects waves back out to sea, preventing erosion of the coast. Also acts as a barrier to prevent flooding.

  Pros:

  Effective, lasts 30-50 years,

  Cons:

  Expensive to build and maintain, creates strong backwash which erodes the wall underneath, £1000-2000 per m.
