Robert Dickinson posted a discussionHow is the St Venant Equation Solved for in the Dynamic Wave Solution of SWMM 5?
Subject: How is the St Venant Equation Solved for in the Dynamic Wave Solution of SWMM 5? An explanation of the four St. Venant Terms in SWMM 5 and how they change for Gravity Mains and Force Mains. The HGL is the water surface elevation in the upstream and downstream nodes of the link. The HGL for a full link goes from the pipe crown elevation up to the rim elevation of the node + the surcharge depth of the node. The four terms are: dq2 = Time Step * Awtd * (Head Downstream – Head Upstream)…See More

How do I calculate the upstream and downstream invert to the forcemain in the model?

I got it. I just changed eveything back to the base, and ran it again. It worked.

Hi Priscilla,
It might be possible to do this if you send me your model. I need the mxd file and ISDB folder. The message you are getting is that the BASE scenario cannot be changed if there are child scenarios.

I'm trying to put the upstream and downstream invert onto the forcemain pipe, but when I go under tools -> Project Preferences, and I try to check (store absolute conduit invert and Store Absolute Junction Rim), I receive a warning. The warning says: Could not change 'Store Absolute Conduit Invert' option. There are multiple conduit sets in teh current project. Is there a way that we can change it to where we can select it regardless if we have multiple conduit sets in the project?

Hi, you can use the invert of the pipes as the offset elevations for the force main. For example, if the pump wet well invert is 10 feet and the force main invert is at 14 feet you should enter 4 feet as the offset depth of the force main at the downstream end of the link.
The node of the force mains should have a surcharge depth so that the force mains will be under pressure.
