  1. What physical factors determine the supply of water? G4 Water Key Idea 2.1

  2. Rivers only 2% of surface freshwater

  3. The parts of the water cycle

  4. Global values of the water cycle

  5. Climate determines where rain falls – Highs and Lows

  6. Freshwater availability varies at different scales

  7. Continent population and fresh water

  8. Upland Wales – temperature and rainfall

  9. Craig Goch Wales - a good reservoir site – why?

  10. London SE England – Temperature and Rainfall

  11. England and Wales – matching supply and demand.

  12. Water Transfer – proposal (controversial)

  13. Water Balance

  14. Botswana – Rainfall Total, seasonality, variability

  15. India – climate, river discharge, aquifers

  16. Relief – river basins

  17. Climate Change – ultimately reduced river flows in some areas Global warming will melt most Andean glaciers in the next 30 years, scientists say, threatening the livelihood of millions of people who depend on them for drinking water, farming and power generation.

  18. Aquifers and groundwater in the UK

  19. Thames Basin - artesian

  20. See pie chart c).

  21. Water supply is not always top quality. Human impact.

  22. Human impact on supply. Lake Chad.

  23. Water scarcity – physical and economic.
