Nodes in InfoSWMM and H2OMAP SWMM
Or how the invert, rim elevation, crown elevation of the highest connecting link, pressure depth and flooded depth interact during a simulation.
Level (invert of the Node)
Elevation (crown – surcharged if the HGL is above the crown elevation)
Ground (either a depth above invert or a Rim Elevation)
Overflow is either lost, stored, increases the HGL, Inlet Controlled or flows to a 2D mesh depending on the values of Surcharge Depth, Ponded Area, Inlet Options or 2D Options, respectively
