HY8:Rating Curve

The rating curve option represents flow rate versus tailwater elevation for the downstream channel. When the Enter Rating Curve option is selected, the user is prompted to define 11 increasing flow and elevation values, as shown below. 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 from the rating curve.
