What are the main types of rock on the Holderness coast? |
Boulder clay (easily eroded) and chalk (more resistant) |
|
|
How do storms during winter effect erosion on the Holderness coast? |
The strong waves and rain cause slumping and mass movement |
|
|
How do the dominant waves from the north east effect the erosion of the Holderness coast? |
Destructive waves erode the beaches and attack the foot of the cliffs |
|
|
What is the rock type is Bridlington? |
Boulder clay |
|
|
What forms of coastal defence are in place in Bridlington? |
Concrete sea walls and groynes |
|
|
What is the main land use of Hornsea? |
It is a holiday resort |
|
|
What forms of coastal defence are in place in Hornsea? |
Groynes (hard engineering, prevent longshore drift but may cause scour at mappleton), raised sea wall (protects from wave erosion and flooding), trees planted in the dunes in the south beach (soft engineering, stabilises the dunes) |
|
|
How far away from the sea is the main road in Mappleton? |
34m |
|
|
What forms of coastal defence are in place in mappleton? |
Two rock groynes and a sloping rock revetment |
|
|
How much money was spent on protecting the coast in mappleton? |
£2.1million, supported by EU funding |
|
|
What is the main land use in Withernsea? |
It is a holiday resort |
|
|
How much money was spent on protecting the coast at Withernsea? |
£6.3million |
|
|
What forms of coastal defence are in place in Withernsea? |
Concrete sea walls, timber groynes, rip-rap, small offshore rock armour reef, beach nourishment, curved sea wall. |

What is the main land use in Easington? |
Major natural gas terminals to the north of the village. Handle 25% of North Sea production. |
|
|
What forms of coastal defence are in place in Easington? |
A revetment was built at the base of the cliff at the terminal site. |
|
|
How much money was spent on coastal defences in Easington and what agreements have been made about the scheme? |
£4.5million. The scheme should be reviewed in 25 years and allowance made for its removal if the gas terminals are no longer required. |
|
|
How was spurn point created? |
Through deposition of sediment from longshore drift and from the river estuary |
|
|
Which estuary does spurn point protect? |
The Humber estuary |
|
|
Which places get protected from coastal erosion? |
Where the losses would be more than the cost of protection |
|
|
How does putting defences in one place effect the rest of the coast? |
It increases erosion further down the coast |
|
|
What advantages are gained from sediment being deposited in the Humber estuary? |
Reduces flood risk. River would be deeper without the sediment and more water would reach further inland, e.g. To Hull |
