Respuesta:

Dorset swanage bay Swanage beach is victim to to erosion putting people and properties at risk. Costal management strategies have been put in place to control this. 1)The first are the gyrone placed in 2005-6 - wooden or stone fences built at right angles to the coast. 2)They trap the material transported by longshore drift creating wider beaches slowing waves 3)environmental - stopped loss of beach material but starved other parts of the coast making them narrower economic - gyrones are not that expensive only costing around £10,000 each, however they require maintainance social - gyrones are unnatractive to tourists and they may detter them from visiting beaches 1)The second one is sea wall - concrete sea walls placed across most of swanage beach 2) reflect waves back out to sea preventing erosion of coast but can create strong backwashe eroding under the wall 3)environmental - they can destroy habitats through scarring which causes waves to damage unprotected areas economic - they are very expensive costing £6million per kilometre to construct but require little maintainance social - they are also unattractive dettering tourists
