%X Traditional flood dispatching methods are usually targeted at the optimal scheduling of gate to meet the hydraulic requirements for a single flow with no consideration of the continuity of the opening or closing of gate,or even the repeated opening or closing operation between different flows,which makes the management more complex.In this paper,a novel flood dispatching mode of one-way continuous opening or closing of the gate in the presence of flows from small to large rate or from large to small rate is put forward for the Hanjiang Gushan navigation and power junction.In the model test,the opening combination of the gate shall be adjusted repeatedly between different flows so that the opening number of the gate corresponds to that of the previous and next flow rate.The flow at the bottom edge of the curved gate should be free to avoid submerging the bottom edge of the gate so as to reduce the vibration of the gate caused by the fluctuation of water flow.Indicators such as the flow pattern of outflow gate and the scour depth shall also meet requirements.The proposed flood dispatching method is simple to operate and runs safely.
