Siphon Network in XPSWMM that also applies to InfoSWMM, InfoSewer, ICM and SWMM5

My classic Siphon Network in XPSWMM that also applies to InfoSWMM, InfoSewer, ICM and SWMM5

Since Siphons are a common question and I found my older XPSWMM training models – here is a reminder:

  1. The Siphon works based on the old Roman Aqueduct system, 
    1. Inflow comes into network
    2. Water falls down into the siphon based on elevation differences between the nodes, in this case the down link
    3. Eventually the HGL in the nodes and links increases and flow comes out the downstream end of the siphon, in this case the up link
    4. It all works on the elevation of the nodes.  There are no other special data requirements.
