	Advantages Beach Nourishment - sand and shingle from elsewhere creates wider beaches slowing down waves Dune Regeneration - creating and restoring sand dunes provides a barrier between land and sea, wave energy is absorbed and stabilisation is cheap Marsh Creation - planting vegetation stabilises mud flats and reduces the speed of the wave. It creates new habitats for organisms Managed Retreat - removing existing defence flooding the land to create a marsh land which reduces flooding of land and is fairly cheap	Disadvantages Beach Nourishment - Can kill other wildlife, very expensive and has to be repeated Dune regeneration - limited to small areas and nourishment is expensive Marsh Creation - Isn't useful where erosion rates are high because marsh can't establish itself. It's fairly expensive Managed Retreat - people disagree with what land is allowed to flood
