Holderness Coast Flashcards
what and where is the Holderness Coast?
Fastest eroding coastline in Europe and is located on the East Coast of England
What are the predicted impacts of climate change on the Holderness coast?
Rising sea levels and erosion
Increased Storm Frequency
Impact on Biodiversity
Eustatic Change
How does climate change exacerbate eustatic change?
Increases global warming which catalyses processes such as thermal expansion and glacial melt
What does the IPCC estimate?
IPCC estimate that sea levels are rising by 4mm per year and by 2100 could reach 1m per year
Why would a rise is sea level threaten the Holderness Coast?
Increases the base height of waves which would lead to more intense undercutting and cliff retreat
How fast are some places in Holderness eroding?
Some parts are already eroding 1.8m a year with some places in Great Cowden eroding 10m per a year
Why is coastal erosion such a large issue?
Threatens socio-economic livliehoods as seen in Golden Sands Holiday park where they have lost almost 100 chalets, reducing business revenue
What could be done to stop coastal erosion?
Implementation of coastal defences such as in Mappleton where they spent £2 million building groynes and other defences
Were the groynes in Mappleton successful?
Let to sediment starvation further down the coast, protecting Mappleton but threatening other places and disrupts the natural sediment cycle.
How does increasing storm intensity shape the Holderness Coast?
Leads to the formation of more destructive waves, leading to less depositional landforms such as sandunes and increasing the formation of erosional landforms such as stacks, arches, caves etc.
How does increased storm intensity threaten the Holderness Coast?
Reduced the deposition of sediment on beaches such as Withernsea and Hornsea which has led to beach retreat as the destructive waves from storms have a stronger backwash. This threatens towns dependent on tourism such as Bridlington
