    Hi, I was wondering if I did the "constant flow" method does the pond need to be using Elevation-Area or one of the other options under the volume type that are available? Also i am aware that the solver should be implicit or the GVF-Rational (StormCAD…

    Paola Espinoza-Youn
    Hi, I have a model in which a pond goes to an outlet structure to go directly to our storm system. However, we want to discard the water quality volume from that same pond to go to arbitrary outfall so it does not affect downstream of our system. I…

    I'm currently running a rather large model that has somewhat extensive hydrology, and I was looking at the option of using the SWMM interface files (rain file, runoff file, RDII file) to save the hydrological results so I don't have to rerun them every…

    No, I do not believe there is a way to customize the data included in the SWMM text output file. However, you should in fact be able to also use the flextable and other tools in SewerGEMS such as element properties, graphs, profiles, etc, to see the results…
