- River Flooding
- Carlise Flood Defences
- Raise flood defences so create a large flood plain with lots of storage. Environmentally acceptable with opportunities for environment enhancement
- Additional Finance Measures
- £1.5 million government grant
- £50000 for energy efficiency grants and £15000 for energy efficiency grants
- 25% council tax discount for flood effected residents.
- £325000 for uninsured vulnerable properties
- £1.5 million government grant
- Phillipines 2008
- Factors
- Physical: heavy rain from typhoon and land was already saturated as it was typhoon season
- Human: not enough warning from government, flash flooding as drains could not cope. Deforestation contributed to run off.
- Responses
- Immediate priority on search and rescue, Red Cross, Coast guard and 1000 army men helped. Social networking helped identify
- Clear up took many weeks, major work to rebuild homes, farmers needed long term support, International aid from UN
- Effects
- Economic: £100 million cost and loss of £% rice production
- Social: 250 killed, 6000 homes cut off, water supplies cut off, mental distress
- Environment: 100,000l oil leaked from Paper Factory and Marinana City
- Factors
- Carlise Flooding 2005
- Long Term
- Houses sustainably rebuilt after long drying period
- Repair bills of £250 million
- Families without insurance found homes were uninsurable and worth much less.
- In July 2007, families still waiting to move back in
- 150 businesses forced to relocate/shut down
- Short term
- Hospitals, schools and police station cut off from impassible roads
- 500 premises flooded from 175mm rain in 36 hours
- 120 flood related injuries, 3 dead
- Long Term
- Occurs when channel can no longer accommodate the amount of water during periods of heavy rainfall, leading to water over topping banks.
- Floodplains give fertile ground which are excellent growing places but the cost of damage to infrastructure and lives is high.,
- Flood Protection
- Sand bags (but may become contaminated)
- Use of ceramic tiles and plastic window frames
- Plastic covers to seal air bricks to stop water coming into the property which can make it very damp
- For Control: disruption and cost of moving people is far greater than simply building defences
- Against Control: can mean places are worse effected, increase in verticle erosion, destroys large areas of wetland.
