Inside SWMM5
What would be the perfect format for a Water Related Engineering Blog?
A note for my readers. I am having an internal public discussion with myself. If you have other ideas or suggestions please email me. I get a lot of emails and very little non spam comments on my
The four cross sectional areas in a link of SWMM 5 and InfoSWMM
Note: Four cross sectional areas are used in a link of SWMM 5. The weighted hydraulic radius (Rwtd) is a function of the Froude Number of the link and the upstream and downstream hydraulic radius. The Rwtd value is used in the computation of the friction slope or … Read the rest

How to set an internal boundary condition in SWMM 5, InfoSWMM and H2OMap SWMM
How to set an internal boundary condition in SWMM 5, InfoSWMM and H2OMap SWMM
- Make the internal boundary node a storage node
- Set the Storage node initial depth
- Give it a large storage area
- Set the offset depth of the link below the storage node to the Storage Node initial

My History with Various Versions of SWMM: SWMM3, SWMM4, SWMM5, XP-SWMM and InfoSWMM
Subject: My History with Various Versions of SWMM: SWMM3, SWMM4, SWMM5, XP-SWMM and InfoSWMMI first learned about SWMM in a brochure from the University of Florida when I was just a 17 year old senior in High School. Water resources and the description of SWMM seemed to be worthy career

The Non Linear Term in the Saint Venant Equation of SWMM 5
Subject: Non Linear Term in the Saint Venant Equation of SWMM 5
The flow equation has six components that have to be in balance at each time step:
1. The unsteady flow term or dQ/dt
2. The friction loss term (normally based on Manning's equation except for full force mains),… Read the rest

1. All of your time steps should be less than the rainfall interval,
2. The hydrology time step should be less … Read the rest
