A venturi flume is a critical-flow open flume with a constricted flow which causes a drop in the hydraulic grade line, creating a critical depth. It is used in flow measurement of very large flow rates, usually given in millions of cubic units. A venturi meter would normally measure in millimetres, whereas a venturi flume measures in metres. For measurement of discharge with venturi flumes two measurements, one upstream and one at the throat (narrowest cross-section), are required, if the flow passes in a subcritical state through the flume.
