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

Welcome Oliver!
Use of times series or fixed water level
- Rating: No Rating
I am the supporter and user of SWMM5. Recently I built a small model using SWMM5 and found some weird outputs. The model build is attached herewith for your reference.
The model is built for run with time series of inflows and downstream water levels. To clearly demonstrate the findings, 2-hour duration is selected for running only. The simulation option is Dynamic Wave with inertial terms kept.
After the model run, I have compared the total inflow at upstream end node with that at outfall node for each reach, see summary attached.
Since the inflow at upstream end during the 2-hour simulation period is constant therefore the inflow at downstream outfall is expected to be constant as well. But this is only true for reach DP3~DP3-out. For reaches DP5~DP5-out and DH6~DH6-out the inflow at downstream outfall is totally different from that at the upstream end, see attached captured Plots of Inflow Time Series.
Does anyone can expalin this problem?
