Practice of hydraulic tracking predictive test for the closure work of large project

The main river closure and open channel closure practice of TGP (Three Gorges project) were taken as example in this paper to study the real-time and whole process tracking test of the closure work hydraulic conditions and the technical routines, technical means, predictive methods, predictive results as well as their functions of hydraulic conditions prediction by means of integrating hydraulic model, which can provide references for the closure work of similar large project.
