Document Summary
Def: areas of stocks and flows of water in the earth. Def: the movement of water within/between compartments of the hydrosphere. Def: the approximate amount of time that water will remain in a certain compartment. The rate of sustainable withdrawal for water increases as residence time decreases. Aka the ability for water to be taken out and still be sustainable increases as residence time decreases. Def: water is growing in demand with population. The population is growing in epi-centers where the local water reserves cannot supply them. The geographic distribution of water does not match that of world"s population. Uneven distribution of the world"s freshwater is leading to conflicts. The five main uses of water in canada. Def: area that shares a common drainage network. This means that fluids on the landscape move downstream. Pollution (chemicals, runoff, etc. ) may contaminate an entire watershed due to this interconnectivity. Surface water is the water that is readily accessible on the earth"s surface.
