Rivers Case Study: Somerset Levels Flashcards
(10 cards)
Which two rivers flow through the Somerset levels?
The river tone
The river parrett
When did the flooding occur
December of 2013- February 2014
Factors name 3 factors that contributed to the flooding
Rain: a series of depressions off the Atlantic Ocean bringing weeks of wet weather
High tides: seawater levels were higher due to high tides and storm surges
Dredging: the rivers were full of sediment as they had not been dredged in over 20 years
Social effects of the floods
- 16 farms evacuated
- residents evacuated into temporary accommodation
- cut off power supply in some locations
- villages such as Moreland and mulchelney were cut off and completely stranded
Economic effects of the flood
- over £10 million costs in damage
- over 14,000ha of land underwater for 3-4 weeks
- over 1,000 livestock had to be evacuated
- work disrupted as roads were cut off
- railway line was closed
Environmental effects of the flood
- sewage and chemicals contaminated the flood water which spread to other areas
- ecosystems destroyed and limited food supplies for animals
Immediate responses
- weather and flood warnings, told to evacuate
- environment agency issued severe flood warnings
- some temporary flood defences were put in place such as barriers and sandbags to limit the water entering homes
Long term responses
Somerset levels and moors action plan
- 20 year plan
What are 3 new management strategies put in place?
Dredging - 8km of the river tone and river parratt to increase capacity
Drain enhancements - develop better drainage so do not need to rely on expensive mechanisms during future potential flooding
Bridgwater tidal barrier - construction of huge tidal barrier to stop high tides contributing to floods
