The manning’s coefficient for a lined trapezoidal channel with a bed slope of 1 in 4000 is 0.014 and it will be 0.028 if the channel is unlined. The area in the case of the lined section is 19.04 m^2 and for the unlined section is 29.09 m^2. What percentage of earthwork is saved in a lined section relative to an unlined section, when a hydraulically efficient section is used in both the cases?

Greg · Answer 1 · 2023-08-15T05:24:28+0000

The correct answer is (a) 0.2 kg/m^2

The explanation: The maximum tractive stress = Yw. R. S

= 9.81 x 1000 x 2.0 x 10^-4

= 1.962 kg/m^2

A wide unlined channel carrying silt-free water has a depth of 2.0 m. The maximum slope that can be given to a channel is 1 in 10,000. Calculate the maximum tractive stress permissible on the bed to prevent scouring.
