Large data output extraction in SWMM


I have developed a model with 33 subcatchments using 1 year hourly  rainfall data. The problem is when I try to get the runoff for all the subcatchments it says '' too many objects to display".

It would be really helpful If you could tell me how can I get the runoff from all the 33 subcatchments together?

  • There is a limit of seven objects to display in the SWMM 5 interface, you will have to plot seven at a time to view the data.  I would also suggest using the System Runoff Variable to see all of the runoff together
