The invert is the lowest point of the channel inside the manhole. If you know the invert of an outfall you can back calculate the node invert elevations of the other nodes from the length of the link and the slope of the link, Or if you have GIS software use a DEM or Tin to estimate the Rim Elevation of a node and then you can calculate the invert elevation. Sure the Rim elevation will change if set to Surface elevations, but they can change even if the Rim elevation is set manually. Want to participate in our Community Map?
