| Abstract: | On the basis of Newton's resistance drag formula and energy equation, the velocity coeficient of parapet wall and calculating method of discharge of large gate opening with submerged weir flow condition are primarily investigated here. The results were verified by the experiments data of three flume models and contrasted with the results of calculation of orifice flow method l and certain useful knowledge was acquired. |
