Figure 8. The first moment of normalized depth averaged streamwise velocity /U, which represents center of gravity of the streamwise flow distribution, along the channel. The inset shows the R2 of the first moment of /U between each curvature and the straight channel condition (C = 0, R2 = 1); a lower R2 suggests greater hydraulic complexity for the first moment of depth averaged streamwise velocity.
