Question:

Figure 14.21 represents the approximate shape of a natural stream channel with levees built on either side. The channel is earth with grass cover. Use n = 0.04. If the average slope is 0.000 15, determine the normal discharge for depths of 3 ft and 6 ft.

6 ft 4 ft 3 ft 10 ft - 10 ft +4 ft 12 ft +4 ft>*
