Design a trapezoidal channel (silt clay) with a slope of 0.002 and a flow rate of 4.58 m3/s (n = 0.024 and m = 3) (15 pts).

a. Calculate the hydraulic radius, the area, and the wetted perimeter.

b. Calculate the dimensions y and b of the channel.

c. Verify the Froude number.

d. Draw the cross-section of the channel with the design parameters.

Neglect the calculation of vertical elevation F (Freeboard)
