<p>PROBLEM TO BE SOLVED: To provide a water flow control system capable of easily adjusting a water flow direction locally in a water tank.SOLUTION: A flow straightening wall 7 partitioning the inside of a water tank 1 having an inflow port 5 and an outflow port 6 is moved along a rail 8 provided in the water tank 1 and extending in a shape of a grid, and a flow passage of water formed in the water tank 1 can be changed by changing a position where the inside of the water tank 1 is partitioned by the flow straightening wall 7. With this constitution, even with respect to error of position prediction of a retention region before construction or generation of a new retention region by the change of a water amount after construction, a water flow direction can be accurately adjusted by movement of the flow straightening wall 7, formation of the retention region is efficiently restrained, and replacement of water can be promoted.</p> |
