Subject: SWMM 5 Weir RTC Rules
This example SWMM 5 model closes a weir based on the depth at the upstream node of the Weir every 0.25 feet. You can see the effect of the RTC rules using a Scatter plot of Weir Flow versus Weir Depth in SWMM 5
This sketch summarizes what happens in a SWMM 5 Subcatchment for Horton Infiltration during a storm event:
1. The event starts out with the potential infiltration rate at the maximum infiltration rate but
2. Decay starts happening right away and the potential infiltration rate starts decreasing until it reaches the
