For a trapezoidal-shaped channel (n = 0.012 and slope So of 0.00015 with an 18-ft bottom width and side slopes of 1 vertical to 2 horizontal), determine the normal depth for a discharge of 850 cfs. (similar to 5.1.10)

2- A 6-m wide concrete-lined trapezoidal channel (n = 0.013) has a sidewall slope of 1V:1.5H, a longitudinal slope of 0.0005, and carries a discharge of 20 m³/s. Calculate: a) normal depth, Yni b) critical depth, yo c) determine the flow regime based on comparison of yn and yc

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.

In a triangular channel, the critical depth for a discharge of 1.2 m³/s is 1.3 m. The critical depth. for a discharge of 38.4 m³/s through the same channel would be: (b) 2 1m
