Hello!
I am trying to model system:
Storage unit (el 100.00), pump, and then forced main and then some outlet (el 104.00) where pipeline connects on gravity sewer system. Slope is always adverse so I am using Dynamic wave.
I started with storage unit, t

Hello:
I want to know by Dynamic Wave Modeling, in forced conduction wich H-W coefficient is asigned to the conduits?
Thanks!

I am trying to extract the time series for the simulated subcatchment runoff in a notepad readable file. As known, the .rpt file does not show the time series results and .out file is in a binary format. Is there a way to include the subcatchment
Read more…Hello,
I just want to know if there is a way to use the SWMM5 file in Arcgis in order to measure the elevation of junctions and the other dimensions as well. Or maybe somebody knows an other way to obtain them quickly. I've already 20 junctions.
Thanks

All I want to know (for now, at least) is where to find and how to import precipitation data into SWMM5 for a rain gage.
I've downloaded files from t

I am to assign outlet to some 10,000 sub catchments, manually doing it doesn't seem professional.
Luckily, name of subcatchment is same name of junction (outlet)
i.e.

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!
Read more…Hi!
Can you tell me how to deal with the fact that it's impossible to model divider under dynamic wave; only with kinematic, but that brings problem of more then one outlet or adverse slope?
Problem is quite simple - flow above 5 lps (per example) shou

I am looking for a way of controlling flows to storage tanks.(Assuming Tank 6 as an online detention tank)
I want to stop the flow from Tank 7 to Tank 6 (vis R13 orifice) once the water depth at Tank 6 reaches to 8.26 m.
Not sure that I have done it
