Dear Lionel,
This matter is explained in Appendix D of SWMM manual under the title of “Command line SWMM”. So in MATLAB you can use below format under DOS window:
"The address of place that SWMM is there" input…

Thanks Robert for your prompt help!
Lionel replied to Fateme Fallah's discussion 'Uncertainty Analysis'
Hi Fateme Fallah,
I am doing something similar but in my case I am varying the infiltration factor. I am not very good with Matlab so require a bit of help on the coding. I would like to check if you have been successful in your attempt to…

Linking Matlab with SWMM5
Hi, I am currently trying to use Matlab to create a set of random values and inputting these random values into SWMM 5 to vary the different parameters (e.g. decay constant) so I will get a range of results. Has anyone done it before? Thanks!See More

SWMM Interface Accuracy - Simple Glitch??
- Rating: No Rating
When rainfall data recorded at the time it falls (see below for example), rather than at a set timestep is entered into my model, there appears to be an error within the precipitation table and precipitation timeseries (see attachment for example). The reporting timestep is set at 1 hour, and the raingauge time interval is set at 1 minute.

SWMM however still seems to produce accurate flow volumes through conduits and produces hydrographs as would be expected with the rainfall data entered. Is this simply a glitch in the reporting interface, and can SWMM therefore accurately use precipitation data in this format??
