Nodes in InfoSWMM and H2OMAP SWMM

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
