What are the advantages and disadvantages of beaches?
Advantages: Nourishment restores and widens the recreational beach. Structures behind beach are protected as long as the added sand remains. When erosion continues, beach nourishment does not leave hazards on the beach or in the surf zone. This is a big advantage when compared with "hard" beach stabilization structures like seawalls or groins. Seawalls may protect structures behind the beach, but they almost always cause the beach in front of the wall to become narrower. If erosion breaches the seawall, then debris from the wall will be left on the beach and in the surf. Since beach nourishment only puts sand on the beach, no debris is left when it erodes. Disadvantages: It's very expensive. It costs around £2,000,000.

Cliff retreat can be prevented by implementing measures such as constructing seawalls or barriers to reduce wave erosion, planting vegetation to stabilize the cliff's base, and limiting coastal development to reduce human interference with natural processes. Additionally, ensuring proper drainage and erosion control measures can help mitigate factors that contribute to cliff retreat.
