    Lower tailwater elevation causing higher water surface stages?

    beej67, You sparked some ideas. The way my tailwater is modeled is through a time - stage node that the outfall pipe link is connected too. I have these set up for 0 hours xx.xx elevation and 24 hours xx.xx to set a constant tailwater. For the invert TW, I'm using the invert elevation at...

    Lower tailwater elevation causing higher water surface stages?

    beej67, This has really stumped everyone in my office and at the other, prime consultant. Ultimately, we have decided to not include the invert TW condition as the receiving body would never allow those circumstances, we originally modeled it to see how the stormsewer would perform under ideal...

    Lower tailwater elevation causing higher water surface stages?

    I have modeled an existing stormsewer system using ICPR (version 3.10) for a neighborhood (existing stormsewer is undersized). I am analyzing 3 different tailwater elevations for the same storm event (10 year elevation from FEMA FIS Study, crown of outfall pipe, and invert of outfall pipe - FIS...
