Case study area 4- the management of the
depositional part of the Dorset Coast.
Booklet p54 on
This short section is not especially about the
solutions, but the ethics of management. Success
in one section of the area inevitably causes
greater problems along the coast. Who should win?
Or should there be any management at all?
Use the prompt sheets to get the main points of
the issue. Then watch the video clip.

What is the problem at Barton?
Why?
The management of the coastline at the large and
wealthy city resort of Bournemouth is the
problem! They are controlling their section of
the beach at the expense of further down the
coast.
3
Bournemouth has been a holiday resort for about
150 years, now. It grew up with the Victorians
who though it fashionable to bathe in the sea for
health reasons, and who wanted other
entertainments as well, like theatres,
restaurants and society parties.
4
With the coming of the railways and cheaper
holidays, it became a mecca for many who sought
sea, sun, sand and a good time. It also became a
famous conference centre.
Kiss me quick!
5
But the resort had a big problem- Longshore Drift
was removing its miles of golden sands! Without
this, there would be no Bournemouth! Whats to
do?
Solution!
Coastal Protection!

So, what is the conflict? A few kilometres down
the coast lies the village of Barton-on-sea. Th
eyre not so happy..

Barton-on-sea management conflict
This area is made up of softer, poorly
consolidated sediments that are easily washed
away by the action of LONGSHORE DRIFT.
Barton is one of the best examples of a
coastal defence issue.

The area lies to the southeast of the city of
Bournemouth.
9
Longshore drift moves sediment towards the
southeast.
The beaches and cliffs of the resort are being
robbed of their material and causing the cliffs
to collapse and the resort to become unpopular
10
The soft, clay cliffs are now being attacked by
the fierce storms that batter this part of the
south coast.
Notice how little beach there is to protect the
cliffs.

Barton-on-sea in the 1950s. Notice the
rotational slumping in the soft cliff face, and
the beach huts on the ledge!

The same coastline today.

Some of the local newspaper articles
about property damage in the Barton area.
15
The solutions?
16
Further along, we can see the shore littered with
rock armour. Read about this in the handout
about coastal protection methods.
A solution? or a failure!
An earlier defence failed in 1975 and a landslide
ruined this factory, covering some of the lower
ruins with gravel.
17
Expensive rock armour has created an eyesore in
the area..
but has it worked?
18
2001. Rock armour lies all along the shore slope
secured by steel netting. It has succeeded in
stabilising the coast, although a
small landslip can be seen above the path behind
the walkers.
19
These are strongpoints- rock armour filled cages
that resist the wave erosion to an extent. They
are very expensive and last only a decade or so.
20
and if Barton is successful.?
