It is of much importance to accurately calculate the water discharge through sluice, because it can ensure the water distributed as required volume for guaranteeing the operation safety of channels. According to the existing design information of the Middle Route of South-to-North Water Transfer Project and calculation principles of conveyance capability of radial gate in submerged flow, several existing calculating formulas have been used to calculate and analyze the conveyance capability of the radical gates on the Project, then the results we have gotten from the calculation were compared with the design value and over value of the channels. The results showed that some radial gates' water discharge through sluice could not reach the design value of the channels' flow rate. If water was transferred according to design value of the channels' flow rate, the flow could not pass some radial gates, resulting in risks of overtopping. Finally, the research summed up the reasons for errors existing in the process of the calculation and gave the advices of increasing the width of the radial gate to ensure the operation security of the actual project and maximize the economic and social benefits.
