Example 5. Runoff Water Quality
This example demonstrates how to simulate pollutant buildup and washoff in an urban catchment. The influence of different land uses on pollutant buildup is considered and both Event Mean Concentrations (EMCs) and exponential functions are used to represent the washoff process.
Surface runoff quality is … Read the rest
SWMM 5 Loss Term Values for various velocities and K values
SWMM 5 has three loss terms available for each link: Entrance, Exit and Other losses. The Entrance loss uses the upstream link velocity, the Other loss uses the center link velocity and the Exit loss uses the downstream link … Read the rest

A note from the past, the SWMM3 and SWMM4 Acknowledgments from their respective manuals for the sake of posterity and in thanks for all of their past efforts.
Maintenance and updating of the EPA SWMM has been continuous since its
inception in 1969-70.
Over the many intervening years … Read the rest
