Q
•coastal management at Lyme Regis: (20)
A
Recurved Sea Wall •150m sea wall •replaces the old, worn wall near the Cobb •protects homes located behind •protects from Easterly winds •helps stop strong storms •redirects wave energy to other, less important areas •long-term protection against destructive coastal erosion and landslips •more sand and shingle on the beach •possible to walk along the whole beach, even during high tide Rock Armour •extended •dropped where there is no beach •the extension of the rock armour and the new jetties all protect the foreshore from waves and stop the new beach being washed away
Stabilising Slope •Lister Gardens was stabilished •provides a natural look •protects ecology like reptiles and dormice •soil nailing means unstable ground is pinned to firmer ground below, reducing landslips •drainage improvements removes water, which is a big factor in landslips
Beach Replenishment •was very narrow between the harbour and the town centre •one sand and one shingle beach •sea wall may have eroded away •keeps beach tourism alive •more aesthetically pleasing •extra sand and shingle on the beach absorbs wave energy and so protects the sea wall and the foreshore from erosion
