A storm drainage channel has the shape shown in Figure 5. It is made of unfinished concrete and has a slope of 0.5 percent. During normal times, water remains only in the small rectangular section. When there is a big rainfall, the upper section allows large volumes to be carried by the channel. a. Compute the hydraulic radius and normal discharge when the water depth is 0.50 m. b. Compute the hydraulic radius and normal discharge when the water depth is 2.50 m.
