A triangular channel with side slope 3H:1V, n=0.012, is to carry a flow rate 10 m^3/s Find the critical depth

5.1.3 Determine the uniform flow depth in a rectangular channel 2.5 ;m wide with a discharge of 3 m³/s. The slope is 0.004 and Manning's roughness factor is 0.015.

trapezoidal channel is designed based on hydraulically efficient channel cross-section. The channel is laid on a slope of 0.0035 and the channel bed material is silt clay. The recommended Manning's coefficient and sidewall slope for silt clay is n = 0.02 and 1V:2H, respectively. What is the normal depth and discharge? Select an answer and submit.
