This paper introduces the characteristics of the large river closure of the Three Gorges Project and the necessity of carrying out this study. The forecasting model of the hydraulic factor for the closure period of the Three Gorges Project is set up based on the empirical curve method of the diversion channel, and the theory of Longkou weir [1]. The practical application of the closure period of the Three Gorges Project shows that the real-time forecast accuracy of the hydraulic factor forecast model established in this paper is satisfactory.
