A uniform flow occurs at a depth of 2.40m in a rectangular channel 2.75m wide with n=0.01 laid on a slope of 0.0021. What will be the minimum height "h" of a smooth hump, extending the entire width of the channel which can be built in the floor of this channel to produce critical depth at the hump. Use Manning's Formula.

Question
A uniform flow occurs at a depth of 2.40m in a rectangular channel 2.75m wide with n-0.012 laid on a
slope of 0.0021. What will be the minimum height "h" of a smooth hump, extending the entire width of
the channel which can be built in the floor of this channel to produce critical depth at the hump. Use
Manning's Formula.
Figure 1:
a). 0.48m
E.G.L.
b). 0.52m
c). 0.27m
d). 0.13m
