Trapezoidal Flume Accuracy
Trapezoidal flumes are rated as accurate to within +/2% by Humphreys and Bondurant and +/-2-5% by the U.S. Environmental Protection Agency. These accuracies are in line with other types of flumes.
Trapezoidal Flume Flow Equations
The free-flow discharge equations for Trapezoidal flume have not been standardized by industry or national standards. However, the equations for individual flumes (Q = cfs, H = feet) have been published in some scholarly articles and publications:
