Question 2: (a) A combination gutter section has the dimension W = 0.5 m, SL = 0.008 m/m, Sx= 0.02 m/m, and a = 0.05 m. The Manning roughness factor is 0.016. Determine the discharge in the gutter if the spread is 2.0 m. Estimate the flow intercepted by the curb opening inlet placed in the composite gutter if the inlet length is 1.75m.
(b) Evaluate the spread and depth at the curb for a triangular gutter section carrying a design discharge of 0.09m3/s and having a uniform cross slope of 0.022m/m, Manning’s roughness of 0.015, and longitudinal slope of 0.014m/m.
