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
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
Building flood walls / bunds – permanent defences
Altering the channel – widening, deepening, straightening - lining in concrete. River Valency Boscastle 2007.
A channel can be built to divert some of the flood water away from the main channel (like a road by- pass)
Individual householders can flood proof their home for about £20,000. Businesses use Floodguard too
Soft options are more ecologically sensitive. e.g. encourage landowners in Upper Catchment to plant more trees
Restore blanket bogs on moorlands – remove any farmers drains
Allow floodplains to stay natural – prevent building on floodplains.
