The allowable depth of water immediately upstream of a culvert, measured from the invert at the first full cross-section of the culvert. Design criteria.
The maximum permissible depth of water surface immediately upstream of the culvert at the design discharge, measured from a datum. Note: datum may differ between software applications; measured from culvert invert or another datum.
The water surface elevation upstream from a culvert entrance invert, measured from a datum. Note: datum may differ between software applications; measured from culvert invert or another datum.
The depth of water immediately downstream from a culvert, measured from the culvert outlet invert.
Measurement from culvert invert, pool, or channel bottom to the water surface.
