Hello, everyone,

I study a area which always occurs infiltration in dry-weather and exfiltration in wet-weather, for there is a stream nearby the sewer.

When the level of the stream is higher than that of the sewer, it happens the infiltration, otherwise the exfiltration happens. 

So if there is a proper way to simulate the process of the infiltration and exfiltration ?

I can set a pipe between the junction and the stream, but how to describe a stream in SWMM ? and how to set the level of the stream?

Thank you!

  • SWMM 5 does have exfiltration from the river reaches but it exfiltrates over the whole depth of the river.  You want to have to have two outlet links at different depths to flow in and flow out of the river.  You can insert a node in the river reach.
