Subject: Example DUPUIT-FORCHHEIMER APPROXIMATION FOR SUBSURFACE FLOW Model in SWMM 5
This example was created from an older SWMM 4 model from 1988 using the SWMM 4 to SWMM 5 converter. The values for the coefficients in this case are A1 = A3
Subject: Force Main Friction Loss in InfoSWMM and the Transition from Partial to Full Flow
You can model Force Main friction loss in InfoSWMM using either Darcy Weisbach or Hazen Williams as the full pipe friction loss method (see Figure 1 for the
Subject: How to Use the Variable Flow Percentage Flow Splitter in InfoSewer
You can use the Variable Flow Percentage Flow Splitter in InfoSewer to model overflow in a node when the two stage solution in InfoSewer does not have a full pipe in the
Purpose: The purpose of this note is to explain a significant dynamic wave routing difference between EPA SWMM 5.0.013 and EPA SWMM 5.0.011 and before. A few people have detected a difference. The previous solution(s) would use only the midpointRead more…
