Because the water in the channel flows with a hydraulic gradient, the realization of multi-point uniform water distribution or quantitative water distribution in a longer channel is a technical problem. At present, the accuracy of channel multi-point water distribution uniformity and quantitative water distribution is improved through the forms of setting an adjustable weir height water distribution weir, a lower opening weir gate, different quantities of gate holes, installing flowmeters, valves and the like, but the device is complex to operate, and certain problems still exist in the aspects of water distribution uniformity and accuracy.
