Subject: How is RDII Storage Simulated in SWMM 5?
If you are using the SWMM 5 Rainfall Dependent Infiltration and Inflow(RDII) feature you can also use the RDII storage parameters to change the RDII runoff by simulating the storage in the Sewersh

I was working on a small project and the first infiltration method I used to calculate the runoff was the Curve Number method. I entered th

I have added nodes to my model and the lists do not follow the model routing order.
Also is there an explanation of the Status report - what some of the tables mean?

I've set up a pretty straight forward model that involves a storage node with a pump deilvering to a force main which discharges to a gravity main. Gravity main has an orifice at the end to deliver about 60l/s. Pump cut in at 2.1 depth cutout at 1.

Dear bloggers and forum users,
I am searching the whole day for a list of all the hydraulic formulas, that are incorporated into SWMM5. The user manual and quality assurance manual don't seem to be the documents containing those... I only know and fin

What value would you suggest to use in Percent routed option? Does it stands only for impervious area or whole area, including pervious area?
Also, where can I add area of manhole (node actually)? I have conduit D=300 mm, and node Max Height 3,2
