Epa Swmm 5.03 How To Run SWMM
The manual includes an appendix that describes how to run SWMM from a command line prompt rather than through Windows, and provides a detailed explanation of the format of the input data file required to run a SWMM simulation. This new version is a complete re-write of the previous release. Running under Windows, it provides an integrated environment for editing study area input data, running hydrologic, hydraulic, and water quality simulations, and viewing the results in a variety of formats. These include color-coded drainage area maps, time series graphs and tables, profile plots, and statistical frequency analyses.A study of the area by the Environmental Protection Agency (EPA) 1973 showed that dredging had drastically increased runoff to the canals, thereby decreasing the area of potential inundation by surface waters during the wet season with subsequent undesirable ecological side effects EPA, 1973, p. The canals had lowered the groundwaterPC-SWMM has a proprietary interface to the USEPA SWMM5 program. The microbial contamination of urban stormwater has an important impact on human health and stormwater reuse.
Thank you all in advance!I am currently working at simulating the complete sewer system of a municipality. Continuity error related to pumping and inclusion of on-site pumping measurements to simulationsHi all,I am reaching out hoping someone can enlighten me with two questions. It also provides a description of the various objects SWMM uses to model a drainage system and a short explanation of the numerical methods used to compute runoff quantity and quality and the techniques used to route this runoff through a system of drainage channels and sewers. The manual explains how to create a SWMM project, how to add new drainage system objects to a map of the area being modeled, and how to edit the properties of these objects.
I checked my status report and it seems to me that… Read more…Calibration of RTK parameters using SRTC tool from PCSWMMHi everyone,I am currently having problems with calibrating/finding my RTK parameters and derive a unit hydrograph for my wet period simulations, so any help is more than appreciated!! I have set up my DWF and flow patterns, and I have calibrated my model using my field flow measurements and the SRTC tool implemented within PCSWMM. When I changed this and runt, my model again, the continuity error went from ~ 3% to 7%. Up to hear nothing is out of extraordinary, however, at first, I set the outlet offset of the upstream pipes to the pumping stations to 0 m as no information was known in advance.My new model, same conditions as above, includes the offset of the upstream pipes for each pumping station. I have likewise set up the calibration for wet conditions and results are fair enough for both cases. I am working with PCSWMM (I apologize as I am not using SWMM per se) to set up my DWFs and flow patterns, run and calibrate the model (I have 7 points for calibration purposes).
However, the output of my model, using the assoicated precipitation values as input for my time series, indicates that there is only about 20 inches of precipitation. How should I understand that my sensibility analysis results in no response from changing my RTK values?Please note that I am ignoring initial… Read more…Greetings fellow SWMMers,I am working on my masters project and I am struggling to get the output of my model to match with the precipitation data I have.My precipitation data indicates that I should have about 50 inches of cumulative rainfall for the year 2008. Everything works nicely in my calibration for DWF and all the steps work well for the RTK unit hydrograph creation, however, when I use the SRTC tool I see no response in my hydrographs (comparing my simulated and observed hydrographs), implying that my RTK parameters have no effect on my hydrograph response. I have also tried to calibrate the RTK parameters for short, medium and long-term responses.
If you do not want to do either then you can send me an email to or and I will do my best to answer your questions. The precipitation data is 24 hour amounts, but I have… Read more…Welcome, my name is Robert E Dickinson (RED) If you just want to read you do not need to sign in but if you want to add a discussion or blog then you need to sign in as a Ning user. I have precipitation data from NOAA for several rain gauges in Nan, Thailand - a rural, mountainous province.

I have taken away any profile questions as well. The acronym RED is me.You can now sign in with Twitter, Facebook, Linkedin and Google as well as an email address.
It would benefit you to read them (if you have not already downloaded the PDF files). It is truly an outstanding aid to modelers and modellers worldwide.
