Coastal Management

Coastal Management:

• Coastal retreat can be managed using a number of different approaches.

• Coastal retreat can be managed using both 'Hard' and 'Soft' engineering.

Hard Engineering Techniques (ex: Durlston Bay in Dorset)

Involve the use of concrete and steel to produce strong / long lasting structures.

• Sea Wall – Built from resistant material and reflects the wave back out to sea.
• Rip Rap (Rock Armour) – Dissipate and absorb the wave's energy.
• Revetments – Break up incoming waves, spread and absorb wave energy.
• Gabions – Absorbs the wave's energy and act as a barrier protecting the cliffs behind.
• Groynes – Prevents longshore drift increasing beach size. Large beach causes waves to 'run out' of energy before they reach the cliff.
• Off-Shore Reef –…
