Boscastle

• On the 16th August 2004 a flash flood occurred in Boscastle
• Causes of the flood

  1. Very heavy rain - a month’s rain in just 2 hours and the soil was already waterlogged
  2. Impermeable rock and clay soils
  3. Located in a steep sided valley
  4. Located near a confluence (both rivers burst their banks)
• Flood Management - £4.5 million

  1. Raised the car park by 10 meters
  2. Made the river channel deeper and wider
  3. Made a drain to remove excess water to the lower course of the river
• Do the flood management strategies work?

  We aren’t sure as there hasn’t been a flood since but don’t know whether it is due to the strategies or the fact there just hasn’t been a flood
