%X Aggravation of the contradiction between water supply and demand has seriously restricted rapid development of social and economic development in Shaanxi Province. With implementation of the South-to-North Water Transfer (Han-to-Wei River transfer) Project in Shaanxi Province, the imbalance between supply and demand of the water resource system would continue to be alleviated. This paper discusses two water supply scenarios within the framework of the provincial South-to-North Water Transfer Project. One is under the condition of water supply only by the Sanhekou Reservoir. The other is under the condition of water supply jointly by the Huangjinxia Reservoir and the Sanhekou Reservoir, in which the water supply scheme is constrained by the transferable water amount from the South-to-North Water Transfer of 10 billion m3 and 15.5 billion m3, respectively. Historic runoff observations from 1954 to 2005 were used in the water supply simulation. Then water supply situations of the benefited areas were elaborated. Results indicated that when supplied solely by the local water supply system, the average deficit rate in the year 2020 would reach 64%, and the average deficit rate in the year 2030 would be 68%. The annual shortage index would be increased accompanied by increasingly serious water imbalance between supply and demand of the benefited areas. When supplied solely by the Sanhekou Reservoir in the South-to-North Water Transfer Project, the average deficit rate in 2020 was found to be 24%, the maximum deficit rate would reach 36%, and the average deficit rate in the 2030 would be 26%. The maximum deficit rate would be 41%. Therefore, the water shortage of the benefited areas would still occur. When supplied jointly by the Sanhekou and Huangjinxia reservoirs with the transferable water amount of 10 billion m3, the average deficit rate would increase from 7% in 2020 to 16% in 2030, the annual shortage index would increase from 3.17 in 2020 to 8.18 in 2030, and the average water shortage would increase from 204.44 million m3 in 2020 to 532.25 million m3 in 2030. Given the transferable water amount of 15 billion m3, the average deficit rate would increase from 2.4% in 2020 to 8.4% in 2030, the annual deficit index would increase from 0.82 in 2020 to 3.31 in 2030, and the average water shortage would increase from 66.5 million m3 in 2020 to 532.25 million m3 in 2030. It was concluded that under the condition of the transferable water amount of 15 billion m3, the water demand for 2020 can be met, but the imbalance between supply and demand after 2030 would increase, suggesting that new water sources be exploited to satisfy the increasing water demand.
