WebThe Manning's roughness coefficients must be entered for each culvert type. HECRAS uses Manning's equation to compute friction losses in the culvert barrel, as described in the section entitled "Culvert Hydraulics" of this chapter. Suggested values for Manning's n values are listed in Table 6-1 and Table 6-2, and in many hydraulics reference books.

"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 ... " - Culvert hec ras
