- Demand for electricity in offices, industries and homes. A Great deal of water is is used for production of electricity.
- Demand for transport which is increasing.

- Largest artificial lake in the UK.
- Opened in 1982

- Poor quality farm land, steep slopes.
- Now a visitor attraction for water and land based activities ie water sports and woodlands. Also woodlands good for forestry.

Features of depostition.
- Hurst castle spit, Dorset.
Coastal Erosion.
- Hallsands, Devon
- Holbeck Hall, Holderness Coast.
Coastal Defence.
- Mappleton, Holderness coast NE coast of the UK, facing the north sea.- Cliffs are made of easily eroded boulder clay.- Eroded at a rate of 1 metre a year.- 4km of land lost.- Rock groyne built to protect area.- Impact has been estimates suggest that it had accelerated cliff erosion south of mapppleton 10m/yr.
Paper One, Coasts.
Sea level change-effects: London + the Thames estury.
- 'City' of London in terms of centre for business, houses of parliment, tourist attractions and housing are all located on banks of the thames. If flooded would create a 'financial diasaster zone'
- 1.5 million commuters work in thames side locations.
- Property assets are estimated at around £100 billion.
- 1.25 million people live in flood zone so insurance would be extremely high.
- 69 tube stations, 400 schools and 16 hospitals would also be affected.
- Infastructure value to high to calculate.
- Barrier cost £534 million but update will be £1.6 billion.
