2. Coastal Recession is affected by:
Fetch – the bigger it is, the bigger the waves will
be and the more the cliff will erode
Geology – cliff recession is faster in soft rocks
such as sand or clay, slower in hard rocks like
chalk and limestone
Coastal defences – if they protect the cliff, erosion
will be less severe and the cliff will retreat more
slowly.
4. UK – Eastern England and the Thames
• In London, Thames Barrier is already
in place to hold back very high tides
• Environment Agency project called
Thames Estuary 2012 will install a
series of new flood walls along the
river.
• There are also plans to leave areas of
open space, on which flood water can
spread .
• The Environment Agency monitors
sea conditions 24 hours a day, 365
days a year.
• If people are concerned they can also
call the 24 hour Flood Line for advice
5. Indonesia
• In the Indonesian Province of Acech, 106 cases
of tetanus and 20 deaths were reported after
coastal flooding associated with a tsunami on
Boxing Day in 2004.
• The resulted in sea water entering and mixing
with the sewage in the drains while drowning
coastal settlements. There were no tsunami
warnings in place and none have been installed
since then.
6. Bangladesh
• In Bangladesh the Coastal Embankment Project has led
to the building of many flood walls
• 500 flood shelters have been built although it is
estimated that 10,000 are needed.
• The local people are now being better educated about
what to do in a flood and flood warning systems are
being put in place.
• There are now laws in place ensuring that the roof of any
new buildings has to be accessible via an outside
stairway so that people can escape the rising waters.
