I'm working on the coupling of SWMM with a homemade 2D superficial flow model. The later is written in Python.
For this purpose, I'm currently writing a Python wrapper for SWMM using ctypes. So far I managed to control a simulation from Python

In swmm 5.1.007, they are the same. which is right?

1. Model Water Quality (TSS for Example)
2. Add the needed inflow Time Series at a Node
3. Include both a Flow

5. The TSS time Series is

seasons greeting.
I am very new to the SWMM5 and working on a project in which i have to develop unit hydrograph and pollutograph in SWMM. please help me out.explain me a detailed procedure to develop hydrograph and pollutograph. Actually I
I lumped my catchment - disregarding the details of the sewer nework and repalacing it with an equivalent subcatchment - but it offten reacts faster than the detailed sewer network model. Any research or idea on this? I tried to include a link down
Read more…Hi, I have a SWMM project representing one catchment, I want to add another SWMM project (of another nearby catchment produced separately) inorder to have a combined project representing both catchments.
What is the best way to do this? Do I have to e
Read more…Hi, I am trying to calibrate a subcatchment. I have semi-automatically tried to calibrate catchment width, slope, Manning's n for pervious and impervious, depression storage for pervious and impervious. I came up with a flow curve shape which looks l

if anyone can help me with this:
How can I develope in SWMM5, an infiltration facility (like infiltration trench, or better, like a linear - not spot soakway) which is located underground (which means it does not receive rainfall itself

Hello, everyone,
I study a area which always occurs infiltration in dry-weather and exfiltration in wet-weather, for there is a stream nearby the sewer.
When the level of the stream is higher than that of the sewer, it happens the infiltration, otherwi

I use dynamic wave to simulate a piece of pipe network, and I set up the outfall boundary to time series which I measured several months ago. The outfall boundary is surcharged when it rains. But after the simulation, I find the total

I found there were many questions about how to call SWMM in matlab, and this problem has bothered me for a long time.
Now I find a way to combine MATLAB with SWMM, it solve my problem, and I want to share with your guys .

Hi evrybody,
Is it possible to introduce in SWMM a new was-off equation or I can only choose from the equation that there are inside?
Imagine any type of equation. Polynomial, or logarithmic, anything. Does SWMM allow the user to include any equation?
