HY8:Constant Tailwater Elevation

A constant tailwater elevation means that the tailwater elevation entered remains constant for all flows. When using this option a channel invert elevation (generally the same as the downstream invert of the culvert) is required so that a tailwater depth can be computed. A constant tailwater elevation may represent, for example, the design elevation of a lake, bay, or estuary into which the culvert(s) discharge.
