Hi,
I’m trying to model two (interconnected ponds as show in the figure below.
The whole catchment area will discharge into Pond-1, and then into Pond-2. The client has specifically requested to provide the control structure for runoff mitigation…
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…

What is the purpose of the "Percent Void Space" column in the properties of a pond's elevation-area or elevation-volume curve?

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…
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…
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…

I've never had to do multiple pond modeling. So this is a first for me. I actually have a couple questions.
1. How do you connect a pond outlet to an Inlet (All of these will be risers)? (Pond 5 needs to overflow into the system using DA-3) . (Pond…
I am trying to generate a report from Pond Pack (CONNECT Edition Update 2) called Pond Routing Calculations (Total Out), see attached image. I cannot find the report anywhere in the report builder. Can anyone point me in the right direction? I tried recreating…

If you're a civil engineer working in the field of site design, you have likely had the need to size detention ponds to attenuate postdevelopment peak flow down to predevelopment rates. Did you know that CivilStorm, SewerGEMS and PondPack include a powerful…
Hi. I typically use PondPack for pond modeling, but have been working more with CivilStorm lately.I have noticed that the pond outlet control structure (P.O.E.) is included in the link in PondPack and conversely the pond outlet control structure included…
Good afternoon,
I am working on a combined sewer network routing model. As part of the model, I have two proposed ponds (forebay and main wetland). I have found that my maximum HGL results in the ponds are different when I switch from Elevation-Area…

Hello LeeFricke,
The pond element is new to StormCAD as of SELECTseries 3 and operates a bit differently than it does with our products (or solvers) that route hydrographs. Since StormCAD uses a peak flow, steady state analysis, you are only looking…

Hello Alex,
Do you happen to have any manholes in your model with the structure type set to "transition"? If so, the memory error you're encountering is a known issue related to that. A patch is available for CivilStorm 08.11.02.62, which you can obtain…
Hello Leonard,
I am a bit unclear on your questions, but I will talk about a few things that I think might be relevant.
First, there have been three major new releases of CivilStorm since version 08.09.26.17. The latest one is 08.11.02.62, and is…
Hello Josh,
Yes, Pondpack can model orifices in series. Since you had also submitted your question to technical support, I took a look at your model and diagram and found the problem.Basically you need to have the 7" orifice and "upstream culvert…
