Hi, am running SWMM from the commandline, meaning I can only access the .RPT file and not the 'Statistics Report' utility which is available only in the GUI. Because I am interested in the inter-event statistics of precipition and flow of a link, isRead more…
You can model water quality as a SWMM 5 inflow time series using the following steps:
1. Model Water Quality (TSS for Example)
2. Add the needed inflow Time Series at a Node
3. Include both a Flow
4. and a TSS Time Series
5. The TSS time Series isRead more…

How to develop a unit area hydrographs(surface water only) and pollutographs in SWMM5 for use in SUSTAINs(System for Urban Stormwater Treatment Analysis and INtegration) land module.
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 downRead 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 eRead 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 lRead more…

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 itselfRead more…
Hello, I am modifying the LID controls from the text editor to perform a sensitivity analysis
What is the meaning of the fifth parameter assigned to infiltration trench surface layer and the fourth parameter to underdrain layer?
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, otherwiRead more…
