The rating curve option represents flow rate versus tailwater elevation for the downstream channel. When the Enter Rating Curve option is selected, a prompt will ask 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.
