Coastal Landscapes Case Studies Flashcards
Tuvalu
Low-lying pacific island
Eustatic sea level rise
Highest point= 4.5m above sea level
Mitigation- migration to New Zealand, those who cannot afford become environmental refugees= cultural tensions
NZ granted citizenship to vulnerable
The Maldives
97% experience erosion
Over 1000 islands
Isolated get ignored due to money spent on capital city Male
Fishing is overlooked due to protection on tourism
NGOs= sustainable living and educate locals
MMF (mangroves for future)- importance as a defence against erosion and flooding
Dorset Coastline
Jurassic coastline - world heritage site (fossils from around 185 million years ago)
Both a discordant and concordant coastline
Lulworth cove- formation after Ice Age- river swollen with glacier meltwater, marine erosion at mouth widens river channel
2013 North Sea Storm Surge
Large depression
Wind speeds of over 140mph in Scotland
Gails of northernly winds cause storm surges 5.8m in Lincolnshire
15 fatalities across UK, Holland, Germany, Belgium
2007 Storm surge in Bay of Bengal
Cyclone Sidr in Indian Ocean
6m high, 223km/hr winds, 3500 fatalities from drowning
Drinking water contaminated= diseases
Why is Bangladesh vulnerable?
Low lying land (1-3m above sea level)
Bays and rivers inland cause travel to further inland
Unconsolidated sediment is easily eroded
Deforestation of mangroves= reduced interception and little to dissipate wave energy
Densely populated country
Holderness Coastline
North East England, fastest eroding coastline in Europe
Clay cliffs
Narrow beaches
Groynes and rock armour at Spurn Head
Waves travel long distances so increased energy
Increased erosion at Great Cowden due to groynes in Mappleton= community conflict
