Appendix
Mean-section and Mid-section methods
The user can select the Mean-section or the Mid-section method for flow calculations. The Mean-
section method divides the cross-section into individual flow segments. Pairs of adjacent verticals are
the limits of the segments. The two edges of the cross-section are given values of 0 for the velocity
and depth. The total flow is the sum of the partial flows of all segments. Figure 15 shows the
definitions and the equation for the Mean-section method.
