Advantages/ disadvantages hard engineering

Advantages

  • Reduce wave power.
  • More permanent
  • Controls nature to an extent
  • Generate power

Disadvantages

  • Expensive
  • Eyesore
  • May not help with sea levels rising
  • Result in consequences elsewhere

Evaluation

Examples of hard engineering: 
-Sea walls: Concrete walls designed to reflect the energy of waves and prevent flooding.
-Groynes: Wooden (usually) barriers built down a beach, trap sand being transported by longshore drift. Resultant wider beach absorbs wave energy.
-Rip rap: Large boulders of hard rock absorb the energy of the waves.
-Gabions: Steel mesh cages containing boulders absorb the energy of the waves.
