Question
Determine whether a 1.5 m × 1.5 m reinforced concrete box culvert with 45° flared wing-
walls and beveled edge at top of inlet carrying a 50-ycar flow rate of 5.4 m³/s will operate
under inlet or outlet control for the following conditions. Assume k, = 0.5.
Design headwater elevation (EL,,) = 31.5 m
Elevation of stream bed at face of invert = 29.87 m
Tailwater depth = 1.43 m
Approximate length of culvert = 60 m
Slope of stream - 1.5%
n- 0.012
