Where is the Holderness coastline located?
on the east coast of England
Why is the Holderness coastline in need for protection?
It is the fastest eroding coastline in Europe
It is rapidly eroding at an average of 1.8 metres a year
state 4 reasons why the Holderness coastline is eroding so easily.
the cliffs are made from soft clay
beaches give less protection to the coast as they don't reduce the power of the waves.
waves travel long distances and are powerful
groynes have been installed, which stop longshore drift, narrowing unprotected beaches
state management strategies for Holderness coast for Hornsea, Mappleton, spurn head and Withernsea
Hornsea is protected by a sea wall, groynes and rock armour
Mappleton is protected by groynes.
Spurn Head is protected with groynes and rock armour.
Withernsea has used groynes and also a seawall
State 3 conflict statements on the Holderness coast management.
increase in erosion at Great Cowden because of the groynes used in Mappleton. This has led to farms being destroyed.
people disagree with where the sea defences are located, especially if it means the land in their community is not protected.
sea defences negatively impact on tourism and reduce the amount of money coming in to the area.
name 4 hard engineering strategies.
sea walls
groynes
rock armour
gabions
name 2 soft engineering strategies.
beach nourishment
reprofiling
2 advantages + disadvantages of gryones
Builds a beach, which encourages tourism
They trap sediment being carried by longshore drift
increases rate of erosion
They look unattractive
2 advantages + disadvantages of rock armours
Cheaper and easy to maintain
Can be used for fishing
They look different to the local geology, as the rock has been imported from other areas
rocks are expensive to transport
2 advantages + disadvantages of sea walls
effective at protecting the base of the cliff
people can walk along them
Expensive - approximately £2,000 per metre.
Not as strong.
2 advantages + disadvantages of beach nourishment
lends in with the existing beach
larger beaches appeal to tourists
needs to be constantly replaced
The sand has to be brought in from elsewhere
