Hydraulic model test is an important reference for the design of large and medium-sized hydropower projects,which can be used to verify the accuracy of hydraulic calculation results and provide scientific basis for optimizing the design. The flow field,flow regime and water surface profile can be obtained by numerical simulation,and this method can be applied to the optimization of hydraulic structure. In this paper,the optimization scheme of the diversion channel guide wall is obtained by the hydraulic model test and numerical simulation.
