Amount of water is not a problem, distribution, availability, and quality is. 3 water threats: pollution, population, climate change. Providing sufficient water for a growing population. Impact of water development on natural and human environment. Humans use 10% of the total annual renewable supply. Agriculture uses 69% of water (often used inefficiently and highly consumptive) Less than 3% of water produced at a treatment plant is used for consumption. Ocean currents and physiographic land influence evaporation/precipitation. Vancouver gets a lot of rainfall while alberta does not: clouds get obstructed by mountains causing rain (windward, all moisture is gathered on vancouver side, leaving no moisture for alberta side (leeward) The amount of water that flows across land surface after precipitation. Factors affecting runoff: climate, terrain, precipitation, volume. Surface storage: lakes, ponds, rivers, marshes, reservoirs, icebergs, glaciers, permafrost.
