Document Summary
Water resources: 1. 75 million people died from lack of water annually, 5 million deaths by waterborne infections and diseases annually, water related diseases cost 125 billion dollars annually. New infrastructure only costs 50 billion annually. The hydrologic cycle: residence time of water in the atmosphere is 10 days while into the ocean it is 3000- After that comes precipitation (also known as rain), and once it reaches the ground, runoff and groundwater heads back to the ocean: a very large source of water from california is not rain, but ice from the mountains. Interception precipitation strikes vegetation and the ground. Stem flow the flow of intercepted water down the trunk or stem of a plant; it is responsible for the transfer of water from the canopy to the soil. Throughfall the process of how wet leaves on a plant shed excess water onto the surface of the ground.
