Calculate flow in compound channels with multiple subsections using the divided channel method. Analyze main channel with floodplains, composite roughness, and velocity distribution.
| Method | Description | Best Used For |
|---|---|---|
| Vertical | Vertical lines from water surface to channel bottom | Most common; main channel with floodplains |
| Horizontal | Horizontal line at bankfull elevation | Well-defined banks with distinct floodplain |
| Bisector | Bisector of angle between water surface and slope | Channels with gradual bank transitions |
Enter subsection parameters and click Calculate to analyze compound channel flow.
