Pickering Flooding Flashcards
Give a background to Pickering..
7000 people around the Beck-flooded 1999,2000,2007 last=85 homes flooded, main road A170
What was the cost of the 2007 floods?
£2.1BN = preventive measures put in HMC (mitigation) ‘Slow the flood’ scheme(forest management) decreasing the PEAK, increase biodiversity.
What problems where there with previous management+ issues with water quality?
66km2 catchment+overgrazing,damaged forestry, poor river management. Water pollution high
What Flood management has been implemented… why was the method changed, …….specifics?
Engineered flood defences X sustainable=holistic:
- land management=slow flow- 100 wood dams
- store water - low level bunds=120,000km2 water storage
- improved water flow -woodland to protect sensitive soils -no burn zones -education of farmers+owners
Evaluate the importance of the human&natural factors affecting river discharge over time. 20m
INTRO:Define river discharge, HF x2+ PF x2=argument
Human-urbanisation, deforestation linked to stores
Physical- topography, size of drainage basin, very
flashy, vegetation ie stores and penetration.
CONC: Natural more significant worsened by poor early management H worsened it.
