- Lake District, Cumbria (November 2009) - MEDC Flooding
- causes
- a massive downpour of rain (31.4cm) over a 24-hour period
- long downpour caused by a lengthy flow of warm, moist air from the Azores. warmer air = more moisture held
- ground previously saturated so additional rain flowed as surface run-off
- imperbeable cumbrian mountains helped water to run rapidly into rivers
- not enough space in channel to hold the fast surge of water
- derwent and cocker already swollen with previous rainfall
- cockermouth is at the confluence of the derwent and cocker
- effects
- over 1300 homes flooded and contaminated with sewage
- a number of people were evacuated, including 50 by helicopter, when flooding cut off cockermouth town centre
- many businesses flooded, causing long-term problems for local economy
- people were told they couldnt move back into damaged homes for a year
- cost of damage was £28,000 average per house
- 4 bridges collapsed and 12 were closed
- 1 dead
- affected infrastructure (electrics, phones)
- point of confluence likely to flood again
- responses
- government provided £1 million for repairs and paid for road/ bridge repairs
- cumbria flood recovery fund helped victims, receiving £1 million in 10 days
- network rail opened temporary railway station in workington
- 'visit cumbria' website provided lists for recovery services and trades
- management
- £4.4 million management scheme
- new flood defence walls - halt speed of river
- sensors in river - help predict excess rainfall
- river dredged regularly - deepens channel
- floodgates at back of houses in waterloo street
