    Static Head

    OK this might not be the right place for this but there a lot of Civil Engineers on these forums so I'm giving it a shot. No text books or other materials seem to quite cover this situation as it...

    As a subset of this topic: our hydrant laterals are generally 6-inch diameter lines. The hydrants, however, have 2.5-inch outlets. Would it make more sense to model a short piece of 2.5-inch line...

    The zipped ISDB file is too large for me to email even after I've eliminated much of the model. Innovyze used to have an http site for this kind of support. Does that still exist?

    I changed the time step but that didn't seem to help. I usually work on the water model but I'm trying to help diagnose this SWMM model. Which files need to be sent to support?

    InfoSWMM Force Main Junction

    Due to the nature of our GIS model, my model has a lot of junctions that are not manholes. How do I get these junctions to function as links in a force main so that effluent does not pond on them?
