WebA circular concrete culvert has a diameter of D = 3 ft, a slope of S = 0.025, and a square edge inlet with a headwall. The inlet is mitered to an embankment slope. Determine the headwater depth, HW, when the culvert conveys Q = 30 cfs under inlet control conditions. To determine if the inlet is submerged, we first calculate WebAug 1, 2024 · The seven different configurations at the outlet to the culvert consisted of the following: no wingwalls, wingwalls at an 8-degree angle with a “rough” (wood) finish, wingwalls at an 8-degree angle with a “smooth” (plexiglass) finish, wingwalls at a 45 degree angle with a “rough” (wood) finish, wingwalls with a “smooth” (plexiglass) truncated … katz uses and gratification theory
