Aquifer example
The empirical equation of Patel et al. seems most accurate of all empirical and analytical equations. Assume an RC well located 100-350 m from a river, in a shallow unconfined aquifer having 8-15 ...Reservoirs are simply where water exists at any point in the water cycle. An underground aquifer can store liquid water, for example. The ocean is a reservoir. Ice sheets are reservoirs. The atmosphere itself is a reservoir of water vapor. Residence time is the amount of time a water molecule spends in one reservoir.Monsoons affect people both in both positive and negative ways. In India and Southeast Asia, people rely on rain from monsoons to fertilize crops, fill aquifers and wells, and power hydroelectric facilities.
