1 Feb 1953
Storm Surge
moved down The North Sea towards low lying East Anglia and the Dutch Lowlands
Deep
depression area moved from the Shetland Area towards the Netherlands
Low pressure
air = sea levels rose
Strong winds
drawn into centre = waves over 6m created
Occurred
during Spring high tide
Southern
North Sea tides reached 2-3m above normal level
Widespread
flooding in East Anglia, the Thames Estuary and the Netherlands
Over 260
died in England
Over 1800 died
in the Netherlands
Causes:
Large parts
of marshland drained in East Anglia
Sea defences
inadequate
After the
flood:
£20 million
spent reinforcing sea and river defences
Thames
Barrier built – operational in 1982
Thames
Barrier not compromised since – after 2030 may not be able to cope
Protecting
London and the SE in the next century would cost £4 billion
