New Mapping Feature in InfoSewer and H2OMap Sewer for Unfilled Depth and Surcharge DepthThis is a new features in H2OMap Sewer 10.5 SP1, Update 1 and InfoSewer SP1, Update 1. You can now map the Maximum Unfilled Depth and Maximum Surcharge Depth during the Simulation in Map Display.
Unfilled Depth is the depth between the Rim Elevation and the Water Surface in the Manhole – the minimum is zero feet or meters
The Surcharge Depth is the Distance between the Rim Elevation and the Water Surface Elevation in the Manhole – it can be positive or negative (negative means the Node is under pressure)
