Determine the cross-section of the greatest hydraulic efficiency for a trapezoidal channel with side slope of I vertical to 2 horizontal if the design discharge is 12 m^3/s. The channel slope is 0.001 and Manning's roughness factor is 0.020.
Determine the flow velocity (ft/s) a most hydraulically efficient trapezoidal channel (m=2) would be designed to carry water on a slope of 0.0015‐m/m excavated in coarse gravel with D75 of 1.2‐in (n=0.03). Consider the angle of repose for the gravel to be 40o and the critical shear stress of the coarse gravel to be 0.456lb/ft2.
QUESTION 1 An concrete triangular channel (n = 0.016) has slide slopes of 2, bed slope of 0.2% and conveys 80 cfs. What is the normal depth, in feet?
Design a trapezoidal channel that is capable of conveying 45 cfs from an elevation of 5000 feet to an elevation of 4500 feet. The total length from one point to another is 15 miles. The channel is to be rough concrete lined (n = 0.02). Try to minimize the amount of excavation required for the channel. If excavation costs are $5/cubic yard, determine the excavation costs. You should try to find the most efficient channel section. Use the area of...
