    Paola Espinoza-Youn
    I have run my model and received a very high continuity error in a specific pond in my model. My pond is going to an outlet structure and then an oufall somewhere else in the model is using that pond for a boundary condition. When i plot HGL, flow in…

    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…

    Jesse Dringoli
    Jesse Dringoli
    Hello Jason, SewerGEMS computes a EQTW table for the pond outlet structure, which is used to determine the outflow for a given headwater and tailwater. So, the tailwater from the conduit should be accounted for. If the grates in your outlet structure…
