Hello everyone,
I realize that this particular thing has probably been discussed more than enough, I browsed through forum aswell as tried to google it.. found some infromation about it but none of the suggested things worked for me.
Basically I'm work

I'm a bit confused regarding what to specify for the elevation of junction's invert.
Should the junction invert be equal to the invert of the 'lowest' connecting pipe?
Kind Regards,
Matt.

As you all should know, about the Unit Hydrograph Editor - Initial Abstraction Depth, one can read:
«Select this tab to provide parameters that describe how rainfall will be reduced by any initial abstraction depth available (i.e., interception

Hi! I have another question about infiltration model. I want to use three different methods to see what's the difference among them. I successfully run the model when I chose Green-Ampt and Curve Number, but when I selected Horton model, the error ap

I am simulating runoff from an ungauged area, hence cannot calibrate my model for width of sub-catchment.

Is there an idiots guide for getting started with SWMM5 in Matlab?
I've been handed a folder with all of the code for a larger model which contains SWMM5 but can't get it to run overall because I can't get the SWMM5 model library (?) to loa

Does anyone know, if SWMM5 plots stacked on top of one another (like in GIRONÁS et al., 2009, p. 132), automatically, or one must do it manually?
Thanks in advance.

I do have one question. Why each time i create a file in SI units and set rain to mm, leave the program, and then open the SWMM (5.0.022) file, and the rain units are in inches (instead of mm), altought the flow units are in LPS?
Thanks in advance.

I only want to analyze the stormwater runoff reduction with LID, so in my case there is no any grey infrastructure. I used real rainfall and climate data for rain gage and climatology files, so I'm a little bit confused which kind of data I should pu
