Since yesterday my the "edit object" button won't open anymore. Also right click and chosing properties won't give information about the object. I have been working with SWMM for a few months now. I already tried to uninstall and install SWMM a few t

I am trying to set a constant outflow concentration as the result for a treatment-equation, i.e. BOD: C=50.
Unfortunately, setting a constant value for the concentration does not work, the result of the effluent concentration would be just
Hi,
I'm having issues with an attenuation feature. I've simulated the rainfall event (24 hours) and now I'm looking to see how long it will take to drain down using outlets with Head/flow relationships (simulated vortex controls e.g hydrobrake). Prob

I'll like to know if is it possible to prevent flooding in nodes (no storage nodes). The problem happens when I close R-1 and R-2 completely, because C-11 reaches its maximum capacity and then N-1 begins to flood. I would like that th

This might be a simple question for some of you but I am still learning the software....
I am trying to model flow on an LID surface and wanted to ask about the outputs I can get from the software and how I can get it. Is it possible to get the

I'm modeling a a simple sewer system. For that I need to define the specific geometry for each sewer of the system. However, when I introduce it, the shape curve viewer only show me the bottom half of my sewer.
Is it simply a problem wi

Thanks a lot. I just want to learn the pest to calibrate SWMM MODEL.

I just started working with swwm 5.1 and I'l already stuck... I try a very simple model to understand how the software works and I can't run anything at all.
Here is the example I'm working on (in fact it's simply the tutorial proposed

In a status report the Volume of flooding in a node and the Maximum Ponded Depth can be seen. From the computed Volume of flooding, how does SWMM compute for the Maximum Ponded Depth?
assuming:
depth = Volume / Area, what area is being consi
