What If London Flooded?
Climate change poses potential threats to London, where 1,250,000 people live/work on the floodplain worth an estimated £80 billion with damage estimated at £12-16 billion.
climate change could increase fluvial and coastal flood risk by a factor of 8 to 12 times.
There are 38 underground stations that could fill with water, eight power stations, 16 hospitals, 400 schools and 500,000 properties.
680,000 properties at risk
London is at risk of flood by:
Tidal - overtopping of existing defences due to a severe storm surge in the North Sea. Also if the tidal defences fail to operate
Fluvial - due to freshwater flows in a tributary that exceeds the capacity of the channel especially if undefended or breached
Surface water - usually as the result of intense rainfall in a summer thunderstorm that exceeds the capacity of the drainage system
The following may also increase flood risk: sewage, water main burst, groundwater, contained water, for example reservoirs
In January 2003, the barrier had to be lowered a record 19 times to prevent flooding during heavy rains.
