5. Draw the sketch of the following cross section of channel and indicate the specified
dimensions.
a Semi-circular section with radius r = 3.0m
b Rectangular section : b=4.0m, and d = 2.0m
C Trapezoidal section : Bottom width b = 3.0m
d = 2.0m
Depth :
Side Slope : 2 horizontal to 1 vertical
i. Calculate the area (A), wetted perimeter (P)and the hydraulic radius (R) of each
channel.
ii. If the discharge of these three channels are equal to 6.0m/s, determine the velocity
of water flowing of each channel and identify which channel has the highest value of
velocity 2, the lowest value of velocity ?
