Instantaneous Pollutant Loading!
Im trying to set up a scenario where an "instantaneous" loading or "spill" occurs in a residential neighborhood and is introduced in to the groundwater. How do I simulate this in SWMM 5.0?

hi
I want to model the behavior of wastewater with SWMM, the problem is that I do not know how to introduce the flow in each pipe. I introduced my data in initial flow and max flow but in the profiel plot _ I get empty pipes please help me

Hello
I am trying to calibrate rainfall-runoff on a small urban catchment (1.5ha). The drainage system is a pipe and gully system, with contibuting areas comprising of concrete footpaths draining towards bituminous macadam roads.
Runoff coefficients ha

I am trying to model a municipal SW system which has several outlets/headwalls in which the storm sewer empties into an open field. During small rain events, the water would infiltrate but during larger events it will flow overland to a stream chann

Hi there,
I am going to edit some parameters in swmm5 input file through swmm5 interface commands.
Is it possible to do that or not?
I can find some commands to read results for example GetSingleResult to view simulation results for particular parameter

Dear all, I am going to use swmm5 interface commands in MATLAB
How can I do that?
I have already used commands below to call swmm5 library in matlab
load library('swmm5','swmm5')
and commands below have been read for example:
swmm_run and swmm_open
but I

Dear Bob, can swmm assess the health degree of the drainage system? I mean, can swmm determine where the drainage pipe misconnection or leakage and calculate the amount of the infiltration and inflow in the system? What is the principle?Thank you a l

I'm evaluating SWMM to determine if it can be used to route two connected ponds. I put together a model
in an attempt to learn the procedure and evaluate the performance of SWMM since I have an upcoming project that will require this analysis.

Hello,
I am modelling Green roofs as LIDs. Each subcatchment represents about 40 hectares of urban area. The current situation (without Green Roofs) is that 80% of the total area is Imprevious and 20% is pervious. When I include the Green Roofs, that

Dear all,I want to use MATLAB and SWMM5 for optimal calibration. In doing so:1) MATLAB has to generate some random values (decision variables) as inputs for SWMM5 (here is width of subcatchments2)Previous subcatchment widths replaced with New ones. S

Hello,
I'm trying to run SWMM 5.0.022 out of MATLAB. I wonder how the unit system works in input file?
for example are the unit for "subcatchment area" and "LID control area" same? where could we change these units? I have the same confusion about the

We are producers of design software for sewage system (Urbano Canalis) which has an option to export geometry to SWMM for calculation purposes.
Until now we did not have any problems with that. Today one customer sent the message that something is wro
