Case Study- Holderness Coastline Flashcards
Where is the holderness coastline?
East coast of England
How far has it retreated over 2000 years
4km
How many villages have been lost?
30
How will climate change affect the coastline?
- increased stormy conditions
- increased erosion (arctic fetch destructive waves)
- eustatic sea level rise
What coastal processes are taken place along the coastline?
- Erosion (soft boulder clay)
- Mass movement (boulder clay prone to slumping)
- Transportation (longshore drift South)
- Deposition (ocean meets Humber river)
Social, economic and environmental problems
- loss of livelihoods
- loss of infrastructure
- loss of sights of special scientific interest
Example of loss of livelihood
80,000 km2 of skipsea farmland is lost each year
Example of loss of infrastructure
Easington has terminal 25 m from cliff edge
Example of loss of sites of special scientific interest
Increase erosion at lagoons near easington provide habitats for birds
Why is the Holderness coastline the fastest eroding coastline in Europe?
- Boulder clay
- Artic fetch
- Mismanagement has increase erosion in some areas
Hard engineering used at Skipsea
Landowner used gabions to protect his caravan park
Hard engineering used at Hornsea
Concrete wall, timber ground and riprap protect the village of 8,000 people
Hard engineering at mappleton
2 rock groynes, revetments
Cost 2 million
Protects village and main road
Hard engineering at easington
Revetments protect gas terminal
Why is mappleton scheme not sustainable?
Groynes used has increased erosion downdrift
Cowden farm at risk of falling into the sea
