Can anyone help me providing a sample SWMM model calibration tutorial set that uses PEST. I have a storm network model and I need to calibrate the model using PEST.
Any relevant suggestion, tutorial or reference is appreciated in advance.

I am new member to this forum as well new to EPA SWMM.
As per city of Calgary need to model storm detention in EPA SWMM 5.1 for the project area 3.3 ha and need to know how much volume of storage required, permissible release rate is 80 l/s/ha.

I am working on a SWMM 5 continuous model. I have a sanitary DWF that varies every three days due to an industrial discharge, so none of the pre-set flow variation patterns (hourly, daily, monthly) will vary the flow appropriately. Is there

Just a query regarding LID's in SWMM. Let's say that impervious sub-catchmant A has a total area of 100 m2.
Let's say that I deploy a LID into sub-catchment A (a rain barrel) and set its surface area as 10 m2 (thus it occupies 10% of sub

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
