Determine if a 2.0 m 2.0 m square-edged reinforced concrete box culvert is adequate for a roadway crossing to pass a discharge of 9.50 m/s. The inlet is not depressed (no fall). The site conditions are as follows: Shoulder elevation = 34.6 m = 113.488 ft Stream bed elevation at culvert face = 30.5 m = 104.04 ft Natural stream slope = 2% Tailwater depth = 1.2 m = 3.936 ft Approximate culvert length = 76.2 m = 250 ft Upstream water surface (head) elevation = 33.5 m = 109.88 ft Note: you will have to work with Imperial units to apply the equations.
