Learning outcomes

After studying this course, you should be able to:

  • describe the different ways in which water is used, and the quantities used for various purposes

  • distinguish consumptive and non-consumptive uses of water

  • recognise uses of water that are elastic in demand and those uses that are inelastic in demand

  • describe and quantify the processes that transfer water between parts of the hydrological cycle, calculate residence times for water in different parts of the hydrosphere, and identify those parts of the cycle that are most suitable for water resources

  • recognise the factors that control precipitation, interception, evaporation, transpiration and how these vary globally.
