Hard Engineering

Advantages

  • Sea Wall - concrete wall prevents erosion and acts as a barrier to flooding
  • Rock Armour - boulders piled up absorb wave energy and reduce erosion and flooding. Fairly cheap
  • Groynes - wooden or stone fences create wider beaches which slow the waves and gives a greater protection from flooding and erosion. Fairly cheap

Disadvantages

  • Sea Wall - creates a strong backwash and erodes under the wall. Also very expensive and hard to maintain
  • Boulders are moved around by strong waves
  • Groynes - Starve beaches further down the coast which leads to narrow beaches no protecting the coast as we'llwe'll
