An Equilibrium Model for Precipitation Resources Assessment in Water Deficit Area

Based on the concept of water balance in Nature-Man System, an equilibrium model for precipitation resources assessment is proposed. The model is possible to be used as an effective tool for tapping the potentiality of all the main conponents of water resources formed from precipitation. The article succeeded to give example for its validation and suggested the mitigating approaches for solving the problem of water shortage in the deficient precipitation regions.
