A series of experiments was conducted to measure velocity distributions in a straight compound-channel flume. Additional velocity data measured in flumes with single rectangular and V-shaped channels were also collected from the work of other researchers to compare the relation between cross-sectional mean and maximum velocities in different shaped flumes with different bed slopes and flow regimes. The results showed that there is a significant linear relationship between the maximum velocity and the cross-sectional mean velocity in flumes with both compound and single rectangular and V-shaped channels. An attempt was also made to determine the relation between cross-sectional mean and maximum velocities in both compound- and single-channel flumes.
