Impacts of the flood:
TASK: Make two lists of the potential impacts of this flooding event. The first list should be short term and the second list should be longer term.
Around 75 cars and 6 buildings were washed into the sea, several boats were also lost, along with uprooted trees and other debris. In an operation lasting from mid-afternoon until 2:30 AM, a fleet of seven helicopters rescued about 150 people clinging to trees and the roofs of buildings and cars. Amazingly, no major injuries or loss of life were reported. About 90% of Boscastle’s economy is tourism and about 2/3 of this income usually occurred during the school holidays.
Causes of the flood:
1. Heavy localised rainfall. 89mm of rain fell in an hour.2. Saturated ground from previous rainfall.3. Topography of the land – the landscape upstream of
Boscastle acts as a funnel, directing vast volumes of water into the village. The valley sides are steep sided.
4. Narrow river channels in the village itself.
Boscastle Harbour
Saturated ground.
The narrow valley can be appreciated when looking upstream from the harbour.
The river channel is very narrow.
How have decision makers responded?
A £4.5m scheme to improve flood defences.
Boscastle main car park.
The scheme stretches along the valley, incorporating drainage, sewerage systems and land re-grading.
Boscastle main car park.
Boscastle car park is being raised in height. This will stop the river from bursting it’s banks so easily.
The river lies here.
This drain allows water to run into the lower section of the river quickly.

The river channel is being made deeper and wider so that it can accommodate more water.

New sewerage systems are being put in place.

Bridges that hindered the drainage of the floodwater are being replaced by stronger bridges that are less likely to get blocked.

Notice attempts to draw in much needed custom.
Reminders of the flood remain throughout the village.
