WebThe culvert flowline slope is the average drop in elevation per foot of length along the culvert. For example, if the culvert flowline drops 1 foot in a length of 100 feet, then the culvert flowline slope is 0.01 feet per foot. Culvert flowline slopes are sometimes expressed in percent. A slope of 0.01 feet per foot is the same as a one percent ... WebBoth forms of the equations are used in the HEC-RAS software, depending on the type of culvert. The nomographs in the FHWA report are considered to be accurate to within about 10 percent in determining the required inlet control headwater [FHWA, 1985]. The nomographs were computed assuming a culvert slope of 0.02 feet per foot (2 percent).
