how to reduce continuity error in specific pond from model?
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…

Void Space Values other than 100%
Paola Espinoza-Youn
Hi, After validating a model before running it I found another error as stated below: "The SWMM engine does not support Void Space values other than 100 percent. Alternate values are ignored." I zoomed into it and it went to a pond and I tried…

Composite outlet structure for Ponds
Paola Espinoza-Youn
When doing a new composite outlet structure with orfice and weir, does the rating table information need to be something that is put in prior to running the model? or is the rating table and curve table populated after running the model? I am updating…

How does "constant flow" for pond seepage method?
Paola Espinoza-Youn
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…

Re: Problem modeling pond outlet structure - SewerGEMS
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…
