Cutoff Divider in the SWMM 5 Kinematic Wave Solution

Subject: Cutoff Divider in the SWMM 5 Kinematic Wave Solution

A divider node in the SWMM 5 Kinematic Wave solution will divide the inflow to a node for two downstream links based on three criteria:

1. Cutoff Divider,
2. Tabular Divider, and
3. Weir Divider

The rule for a Cutoff
