Flood Management Strategies

1. Flood Management Strategies 1) Explain how each method works … 2) give good points & bad points of each strategy 3) Give viewpoints of different groups of people 4) Consider whether the strategy is sustainable

2. Sustainable

3. Planning - Land Use Zoning

4. Preparation - homes and businesses

5. Prparation – well beforehand

6. Preparation - beforehand

7. Preparation

8. River Management – hard engineering e.g. Dams Hard options tend to be more expensive and have a greater impact on the river and the surrounding landscape. They involve engineering (building) a solution to the flood problem. Building dams e.g. Talybont Reservoir

9. River Management – hard engineering Building flood walls / bunds – permanent defences

10. River Management – hard engineering Altering the channel – widening, deepening, straightening - lining in concrete. River Valency Boscastle 2007.

11. Hard Engineering – flood relief channels A channel can be built to divert some of the flood water away from the main channel (like a road by-pass)

12. Hard Engineering – flood protection Individual householders can flood proof their home for about £20,000. Businesses use ‘Floodguard’ too

13. A Flood Resilient Home

14. Soft Engineering - afforestation Soft options are more ecologically sensitive. e.g. encourage landowners in Upper Catchment to plant more trees

15. Soft Engineering – remove drains Restore blanket bogs on moorlands – remove any farmer’s drains

16. Soft Engineering – natural floodpains Allow floodplains to stay natural – prevent building on floodplains.
