Hard engineering is ways of managing coastal erosion by dissipating the wave energy. This is often expensive and uses structures made of concrete, steel, wood and rock.

Sea Walls:

  • Stops waves reaching land and eroding coast by reflecting waves out to sea


  • Reflects waves to stop erosion

Cost and Problems:

  • Prevents easy access to beach
  • Suffers wave scour where destructive waves remove beach
  • Ugly and unnatural
  • £2000 per metre



  • Stick out perpendicular to sea. Made of wood


  • Stops longshore drift, traps sand on beach

Cost and Problems:
