To provide a flow control method and a flow control device using a gate which can achieve a stable flow control quickly even in any form of outflow by identifying a target opening with respect to a target flow rate at the time of free outflow and submerged outflow in flow control by the outflow at the gate bottom edge.
In a flow control method using a gate in which a flow rate in a river channel and a water passage is controlled by the outflow at the gate bottom edge, a secondary side water depth h2 of a gate 1 with respect to a target flow rate is predicted and set according to flow-down characteristics of the river channel and the water passage, and the gate opening is controlled by using the gate operation opening calculated by using the measured value of a primary side water depth h1 of the gate 1, the predicted set value of the secondary side water depth h2 of the gate 1, and the target flow rate, as a target value.
