Soft engineering case study Flashcards
Where?
Wallasea island
South-west England
Coast
Strengths
Less maintenance than hard engineering No opposition from land owners Creates valuable habitat Good for conservation efforts Sustainable
Weaknesses
Cost £8million
Stakeholders
RSPB DEFRA EA Crossrail Natural England
Opportunities
Ecotourism Similar plans can be used in future if its successful Conservation Conservation of migratory birds Reduced effect of climate change
Threats
Sea level rise
Size
Over 15km of access routes
115 hectares new saltmarsh
RSPB
Conservation for migratory birds
Crossrail
Provides 7million cubic metres of clean dirt for project
Sustainable removal of dirt from railways
Why was this area chosen?
Sufficiently large Little chance of estuary damage No adverse effect on local population Remote No opposition Coastal squeeze rather than erosion Importance of sustainability
Economic impacts
Reduced flooding means less impact on fisheries so less income impacts
Loss of farmland means less agriculture income
Increased living potential from multiplier effect
Social impacts
Increased recreational opportunities
Improved infrastructure
Improved aesthetics
Environmental impacts
Provides habitat for many species ie. avocet
Re-establish lost breeding sites ie. kentish plover
Establish new populations ie. black winged stilts
Creates saltmarshes as carbon sink
