The Changjiangriver to Huai river water diversion project plans to divert water from the lower reaches of the Changjiangriver to replenish water in the middle reaches of the Huaihe river, mainly for the purpose of ensuring urban and rural water supply, developing Jianghuai shipping and improving river and lake ecology. In this paper, we predict the four aspects water demand including domestic, industrial, agricultural and ecological water demand in the river channel in 2030. According to the rules of lakes and water supply projects, we can obtain the water supply under different typical years. The balance of water supply and demand is analyzed for different circumstances. It is concluded that the average annual total water demand in the planned area in 2030 is 18.335 billion m 3 , the total water supply is 15.356 billion m 3 , and the water shortage is 2.979 billion m 3 .
