A a = 0.55 (m) × b = 0.3 (m) concrete box with Manning roughness coefficient of n = 0.016 is to be placed under a roadway. During the T = 100 years design storm, it is expected that water will pond behind the culvert to a height h = 0.2 (m) above the crown of the culvert. If the culvert entrance is to be rounded with the exit loss coefficient of Ke = 0.2 and discharge coefficient of Cd = 0.45. If the slope of the culvert is S% = 0.2 and the length of the culvert is L = 4 (m),

estimate the flow rate through the culvert.
If the flow rate drops down to 20% of the design storm, estimate the depth of water behind the culvert.

A rectangular laboratory channel has a bottom width of 6.0 in, a Manning roughness coefficient of n = 0.010, longitudinal slope of 2% (So = 0.02). The discharge is 180 gpm. Assume α = 1. The water depth is 2.5 inches at Point A, and 3.0 inches at Point B. The normal depth is 2.066 in and critical depth is 3.228 in. (a) Use the direct step method with one step (Δy = 0.5 in) to determine the distance from...

A rectangular channel 2 m wide has a bottom slope of 0.01 and a roughness coefficient of 0.017. A sluice gate 2 m wide is located in the channel. The sluice gate has a contraction coefficient of 0.61 and a discharge coefficient of 0.58. The depth of water just upstream from the gate is 2 m. The depth of water just downstream from the gate is 0.5 m. Determine how far upstream from the gate the depth of water will...

A 40 m long concrete box culvert (n = 0.012) will be laid on a slope S = 0.001. The inlet will have a headwall parallel the embankment and the entrance will be beveled on three sides. What should be the width, b, of the culvert if D = 1 m TW = 1.1 m, Q = 1.8 m3/s, and the HW < 3.0 m. Assume that the outlet creates the maximum headwater for your solution.

How much load can safely be carried by a 20 m long, 0.3 x 0.3 m square concrete pile driven in very stiff clay. Address the safe load issue but not the settlement issue. Soil properties: su = 100 kPa, qc = 5 MPa, fc = 70 kPa, pL = 500 kPa, E0 = 7.5 MPa, Cc = 0.3, cv = 10-4 cm2/s, γ = 18 kN/m3. If you need additional properties assume reasonable values.
