The equations of discharge coefficient for under flow through the openness of vertical lift weir were developed for the calculation of free and submerged flows. In hydraulic characteristic analyses, the variation of upstream depth and the depth difference between up and down stream of gate depend on the gate openness and discharge. For free and submerged flows, the equations of discharge coefficient were developed by the definition of submergence ratio and the ratio of gate openness height to depth difference of up and down stream at gate in addition to the submergence ratio as well. Correlation analyses were carried out between flows of the experimental and the calculated by the developed equation of discharge coefficient. For free flow, the root mean square error (RMSE) and mean absolute percentage error (MAPE) were $0.0008m^3/s$ and 4.87%, respectively. There were 67% and 92% calculation discharges within the 68% and 95% confidence intervals (CI), respectively. For submerged flow, the RMSE and MAPE were $0.0006m^3/s$ and 4.18%, respectively. There were 75% and 94% calculation discharges within the 68% and 95% confidence intervals (CI), respectively, indicating a high degree of correlation between the experimental and calculate discharges results in the applicability.
