Give 2 domestic uses of water?
Washing dishes Flushing toilets
Give some reasons for the inreasing demand for water?
Increased population Increased wealth Climate change Industrialisation
What is water withdrawn?
Total volume of water removed but returned after Ie HEP from a reservoir
What is water consumed?
Total volume of water removed nut not returned afterwards Ie agricultural irrigation
Are low income countries more likely to use more water, or high income countries?

What is a reservoir in terms of the hydrological cycle?
The amount of stored water in each part of the hydrological cycle They’re in a state of dynamic equilibrium
What a the 2 main processes that drive the hydrological cycle?
Solar energy Gravitation potential energy
What is the input to the hydrological cycle?
Precipitation
What are some outputs to the hydrological cycle?
Evaporation Transpiration River discharge
What are some reservoirs in the hydrological cycle?
The atmosphere Surface water and ice Groundwater
What are some processes in the hydrological cycle?
Interception Infiltration Percolation Run off
How do you calculate residence time?
Volume of water/rate of transfer
What are 4 ways that humans impact the hydrological cycle?

Topography Geology Catchment area Infrastructure / land use Little soil erosion Hydrology
Give some environmental impacts of building a reservoir?
Habitat change Wildlife barrier Change in river flow/ shape Microclimates
Give some water sustainable management techniques?
Artificial recharge of aquifers Regulating rivers from reservoirs Inter basin transfer Afforestation Unexploited aquifers
What is grey water?
Water that is still relatively clean but has been used before ie for cleaning dishes
Give some water conservation methods?
Use of low water appliances (dual flush toilet) Low volume irrigation (drip irrigation) Xeriscaping Using grey water Control of pollution Reduce wastage (through dripping appliances and pipes)
What is xeriscaping?
Planting areas with species that are adapted to drier conditions which need watering less
Give some examples of things to control pollution of?
Sewage treatment Acid mine drainage Buffer strips to reduce fertiliser run off
