Example 3: Inlet/Outlet Control Given: You've been tasked to evaluate an existing storm culvert passing under a local highway Length = 200 ft Diameter = 42" n=0.024 Slope = 0.01 Normal depth of flow at the outlet = 24" Maximum allowable headwater = 6 ft Entrance = square edge headwall Find: A) What is the maximum flow that can pass through this culvert under inlet control conditions? B) What is the maximum flow that can pass through this culvert under outlet control conditions? C) Which condition controls: inlet or outlet? Solution: Profile Cross section
