Determine normal depth for a 4-m-wide trapezoidal channel that is carrying a discharge of 49.7 m3/sec. The excavated earth channel is well maintained (clean) with a flow sl.ope of 0.2 percent and side slopes of 4: l (H: V). Solve using Figure 6.4 (a) or successive substitution. Check your solution using appropriate computer software.
