<p>PROBLEM TO BE SOLVED: To suppress the reduction of an outflow rate resulting from a time difference necessary for the closing of a plurality of dam gates.SOLUTION: When an outflow rate setting value receiving part 26 receives a command for discharging water at a second outflow rate which is larger than a first outflow rate by opening a gate which is different from a plurality of gates after closing a plurality of the gates from a state that a plurality of the gates which are arranged at a dam are opened, and water is discharged at the first outflow rate, a gate control part 28 decides close operation start times Ts1, Ts2 of a plurality of the dams so that gate close operation finish times Te of a plurality of the gates coincide with one another. Furthermore the gate control part 28 starts close operations of the respective gates at the decided close operation start times Ts1, Ts2 of a plurality of the gates.</p> |
