A modified version of the Venturi flume is the Parshall flume.
2.
Styles of flow measurement flumes include : Palmer-Bowlus, Trapezoidal, and Venturi Flume.
3.
A venturi meter would normally measure in millimetres, whereas a venturi flume measures in metres.
4.
As a result, between 1920 and 1931 the rivers Ashop were also diverted from the Ashop valley into the reservoir using tunnels and a Venturi Flume.
5.
Beginning in 1915, Dr . Ralph Parshall of the U . S . Soil Conservation Service altered the subcritical Venturi flume include a drop in elevation through the throat of the flume.
6.
Measurement of discharge with venturi flumes requires two measurements, one upstream and one at the throat ( narrowest cross-section ), if the flow passes in a subcritical state through the flume.
7.
A venturi flume is similar to the Parshall flume, without the contoured base, but the cross section is usually rectangular, the inlet shorter, and there is a general taper on the outlet similar to the venturi meter.

Originally designed by Troxell and Taylor in 1931 and published under " Venturi Flume " as a memorandum from the office of the Ground Water Branch, USGS, the design was again brought to the attention of potential users in Taylors'paper " Portable Venturi Flume for Measuring Small Flows in 1954.
