Flooding Case Study. MEDC: Boscastle, North Cornw

  • Situated in the South East of the UK, and the North of Cornwall. Boscastle is home to neasrly 2000 people and attracts 1.2 Million people per year.
  • On 16th August 2004, Boscastle was hit by one of the worst floods ever to affect the UK. This one in 4000 year event had many devastating effects. The villiage that is no more than 5 miles long suffered changes that would lsat a life time.

Causes.

  • The flood was caused by a torrential storm, which saw 185mm of rain fall in 1 hour.
  • Water reached the channel of the River Valency extremely fast due to the steep valley sides of the area.
  • This resulted in a 2 meter rise in the river's level in 1 hour.
  • The river then burst its banks, leading to a 3 meter wall of water sweeping through the villiage.
