Case Study: Holderness Coast
The Holderness coastline is the fastest eroding coastline in England and it
is 45km long. The area is made of boulder clay left over from the ice age so
rapid erosion will continue until waves begin to hit the chalk behind, which is
harder to erode.
Holderness is located in the North East of England, North of Grimsby and
South of Flamborough. Holderness is eroding because of the material that
the cliffs are made of (clay), which is easy for the powerful waves to beak
into. The processes that are eroding the cliffs are weathering, abrasion
and corrosion. In Mappleton stone groynes have been put in place to slow
the process of cliff erosion. This has negative effects as Withersea has
been deprives of beach material causing the rate of erosion to increase.
The erosion of Holderness coast impacts people in lots of different ways.
For example, it could be putting their lives, homes and jobs in danger. Also
people who are looking to move away from this area struggle due to the
face that house prices have fallen dramatically because of the rate of
coastal erosion increasing. The Holderness coastline is being protected
with many different defences, such as:
Groynes
Sea Walls
Rip-rap
These are put in place to decrease the rate of cliff erosion. In some places,
however, they leave a coastline with no defences and just leave it to let
nature take its course. In Mappleton stone groynes were put in place to
reduce the rate of erosion. It did this well but caused problems further
South in Withersea. Withersea has been deprived of beach material and
has seen erosion rates increase dramatically since the placement of these
groynes. A few miles South of Mappleton there is a sparsely populated
farmland named Great Cowden. Great Cowden is unprotected against all
types of erosion and has scarcely any beach so has a high erosion rate.
It is difficult to make decisions on coastal management because coastal
defences that have positive effects in one area can quite easily have
negative effects on another. Coastal defences are extremely high priced
and government cannot afford to put them in every area that they are
needed. Views are varied among people because the public feel their lives
may be in danger but the government do not have the sort of money to
protect to the desired standard.
