- Water on the Land
- Managing Water
- Managing water supply
- Build more reservoirs to store more water
- Can involve flooding settlements and relocating people
- Fixing leaky pipes to reduce water lost
- Transfer water from areas of surplus to areas of deficit
- Issues: Equipment needed is expensive, could affect wildlife, might be political issues
- Build more reservoirs to store more water
- Demand across the UK
- In 25 years water use has gone up 50%
- South East and Midlands have high population density-high demand for water, water deficit
- North and west have high rainfall-good supply of water, water surplus
- UK population predicted to increase
- Reducing demand for water
- Have water meters installed to charge people for the exact volume of water they use-make them want to use less
- Reduce amount of water used at home-shorten showers, don't leave tap running, only use washing machines and dishwashers when they're full
- Managing water supply
- Resevoirs
- Case Study
- Impacts
- Social
- Many jobs have been created
- Lots of recreational activities on reservoir-sailing, windsurfing, birdwatching, cycling
- Two villages demolished to build reservoir
- Economic
- 6km of land flooded-some farmers lost livelihoods
- Boosts local economy-popular tourist attraction
- Environmental
- Variety of habitats found at reservoir
- Hundreds of species of bird at reservoir, tens of thousands of waterfowl come in winter
- Ospreys re-introduced to central England
- Site of Special Scientific Interest-wildlife is protected
- Large area was flooded to create reservoir so some habitats were destroyed
- Social
- About
- Designed to supply East Midlands with more water
- Covers 12km area filled by Rivers Welland and Nene
- Rutland Water in East Midlands
- Areas around reservoirs used as nature reserve and for recreation
- Sustainability
- Can't deplete water supply or damage environment
- Water supply needs to be sustainable for future population
- Use the reservoir in a sustainable way
- Impacts
- Case Study
- Hydrological cycle
- Inputs: Water put in
- Precipitation-Snow, rain, hail, sleet
- Transfers/ flows: Movement of water within the cycle
- Overland flow/ surface runoff-Water flow which occurs when soil is saturated and excess water flows over the land
- Through flow-movement of water through the soil to a river channel
- Infiltration-water on the ground enters the soil
- Percolation-Movement and filtering of water through porous materials
- Interception-Precipitation that doesn't reach the soil but is taken up by vegetation
- Stores: Places where water stops within the cycle
- Ground water store-water held in aquifers below the water table
- Outputs: Water leaving the land
- Evaporation-Water changes from a liquid to a gas
- Transpiration-Water is absorbed by plants and evaporated into the atmosphere through the leaves
- Inputs: Water put in
- Managing Water
- UK population predicted to increase
