- flood management strategies
- Hard engineering - attempts to control floods
- Dams
- dams are large concrete barriers built across a river - the water behind the dam is tried is a reservoir. the water is gradually released downstream.
- very effective, lasts a long time
- expensive, lots of work
- Levees
- artificially raised banks, increasing channel capacity to reduce flood risk.
- works well, creates a public path
- expensive, looks bad
- Straightening meanders
- involves cutting through a meaner creating a straighter channels to speed up flow of water
- works well, lasts a long time
- expensive, looks bad
- Dams
- Soft engineering - tend to reduce floods
- flood plain zoning
- this is where land is used in a way that minimises the impact of flooding depending on how at risk an area is. Low costs areas land-uses such as playing fields are closer to rivers whereas higher costs factors and houses are built further away
- doesn't control floods, not everyone sticks to it
- flood waring system
- in the UK if you live in a flood risk zone you details are kept on a database. in an event of a flood the council will send a text message to warn you and how to prepare for the flood
- doesn't control floods.
- washlands
- looks natural, doesn't cost anything
- destroys land, doesn't last.
