Coast Case Strudies

Question 1

Effects of coastal erosion on a place you have studied

Answer 1

House prices in skipsea dropped by 90%
Farmland being lost at 2m per year
Long beach caravan park is falling into the sea
Hornseas sea wall coat 8 million
The b1242 is a vital link and could potentially be lost into sea, would cost a lot to replace

Question 2

Causes of coastal on a place you have studied

Answer 2

Soft boulder clay which when it gets saturated it slumps easily and it erodes quick
The prevailing wind faces the coastline bringing in waves from Norway this creates a big fetch meaning the waves are a lot more powerful

Question 3

Effects of rising sea level on a place you have studied

Answer 3

Japanese government has given the Maldives 60 million to build a 3m high sea wall around the capital male
Carbon neutral country
If the main airport gets flooded then international tourists won’t be able to come affecting the economy
Fish industry being disrupted, Tuna is the country’s largest export therefore reducing the country’s income
Water supplies being destroyed from pollution, can’t meet water demands

Question 4

Maldives

Answer 4

An island surrounded by the Indian Ocean
They are only 3 m above sea level so vulnerable towards climate change
80% of islands could be lost

Question 5

Using an area you have studied what has been done to manage coastal erosion - hard

Answer 5

Holderness coastline
2 rock groynes. 2 million, mappleton 1991. Protect coastal road n village
Bridlington is protected from erosion by a 4.7 km long sea wall n wooden groynes
Sea wall and groynes and rock armour that protect Hornsea from erosion and flooding

Question 6

Why do these hard engineering strategies on the holderness coastline cause problems elsewhere

Answer 6

Groynes at mappleton cause narrower beaches further down the coast which increases erosion e.g. Cowden farm is at risk at falling in the sea
Less erosion of holderness means the Humber estuary doesn’t receive as much material increasing the risk of flooding

Question 7

What are the natural sea defences at spurn head

Answer 7

Sand dunes on eastern side as the wind has bounced and blew sand particles up the beach
Mudflats develop at western side of spit as water energy slows and deposits material
Spiky cord grass found in salt marshes it binds the mud together and makes it difficult to be washed away, they live here because they can survive in salt water
Slatmarshes protect the coastline as it’s a good natural sea defence
Birds like oystercatchers and geese live here

Question 8

What is being done to conserve spurn head

Answer 8

Issue- nesting grounds being disturbed- controlled tourism- nesting season visitors cut down
Issue- no facilities for tourists
The spurn bird observatory is being built with eating and toilet facilities and information about spurn head
Spurn head disappearing into sea- rebuilding groynes to trap sediment
