  • Physical factors affecting water supply- Climate, river systems and Geology
    • Climate
      • Regions near the equator receive high levels of annual precipitation
      • Equatorial areas such as Amazon have 2 distinct periods of wet weather per year.
      • Monsoon areas of Asia have 1 very wet season
    • River systems
      • The world's major rivers store large quantities of water and transfer it across continents.
      • River flow increases downstream as more tributatries feed into the main river.
    • Geology
      • Where rocks underlying a river basin are impermeable- water will remain on the surface creating a high drainage density
      • Aquifers can store huge amounts of water underground
