A storm drainage channel in a city where heavy sudden rains occur has the shape shown in Fig. 14.20. It is made of unfinished concrete and has a slope of 0.5 percent. During normal times, the water remains in the small rectangular section. The upper section allows large volumes to be carried by the channel. Determine the normal discharge for depths of 0.5 m and 2.5 m.
