Tailwater Data
HY-8 provides the following options for calculating the tailwater rating curve downstream from a culvert crossing:
Uniform depth is used to represent tailwater elevations for both a defined channel shape and an irregular channel. The cross section representing these two options should be located downstream from the culvert where normal flow is assumed to occur (downstream from channel transitions, for example). The calculated water surface elevations are assumed to apply at the culvert outlet.
