  • The Boscastle flood 2004 - MEDC
    • Risk of flash flooding increased by...
      • Building on flood plains
      • Canalisation of rivers
      • Development of catchments - especially on steep slopes
      • Removing trees and vegetation
      • Not maintaining drains and gullies
    • Effects of the Boscastle flood...
      • 25 business properties destroyed
      • 50 buildings flood damaged
      • 4 foot bridges washed away
      • Visitors center destroyed
      • Pavements and gardens damaged by the weight of the water
      • Stress and anxiety of local people
      • Insurance companies paid out an estimated £20 million to repair damage
    • OPENING...
      • Boscastle had been affected by minor flooding events before 2004, but was unprepared for a flood of the scale they experienced in 2004
      • The flood destroyed homes and businesses and swept away a hundred vehicles
      • Bridges and roads were damaged, and rescue services had to mount the largest peacetime rescue operation in Britain's history
      • When the flood water receded, thousands of tons of mud and debris were left in the lower part of the village
      • The effect on the local economy was devastating - the area relies on tourism for 90 per cent of its income, most of which is earned during the summer months
    • Responding to the flood...
      • After the 2004 flood in Boscastle the environment agency investigated and found human factors...
      • The building of low bridges, which trapped boulders and trees that had been washed down the valley
      • Allowing trees to grow alongside the river; during the flood these were washed into the river, blocking channels
      • Artificially narrowing the river as it passed through Boscastle, reducing its carrying capasity
      • Building alongside the river and not allowing for its expansion during periods of high water flow
      • Removing vegetation from the sides of the valleys, which increased the rate of surface runoff and meant that rainfall reached the river quickly
