Question
A trapezoidal channel is designed (not most efficient channel) to carry 24+Z m3/s on a slope of 0.002 m/m. The channel is unlined, and in order to prevent erosion, the maximum allowable velocity is 1.2 m/s. The side slope must not be steeper than 1.5H on 1V, and the Manning ‘n’ value is 0.03. In order to meet these requirements, what flow depth and bottom width should be used? (Z=15)
