Hi everyone,
I need to run a large number of simulations (approx. 15000) with different sets of LID design parameters. My objective is to get model responses (e.g. infiltration, surface runoff, etc.) against different sets of LID design parameters. I

Very new SWMM user here. Interested in defining some LID Controls so I can select them for my subcatchments in the drop down menu in the editor.
It seems I need to first define the Controls and how they are routed using the specialized pro

if anyone can help me with this:
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 itself

Does the 'area of each unit' when modelling rain barrels in SWMM represent the area of the impervious area contributing run-off into the rain barrel (for example the roof area) or the cross sectional area of the rain barrel itself? SWMM user manual a

Has somebody ever try to simulate a green roof with a bio-retention cell?
I can't understand exactly the meaning of some parameters, so if someone has an example on a real case of study, I will be happy to take a look!
thanks!!

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
