1. Determine the backwater profile created by an obstruction in a channel causing a backup


of 5.0 feet. The channel is trapezoidal as defined below and conveys a discharge of 200 cfs.


Use the standard step method.

2. Compute a chart for elevation versus discharge for the channel in problem 6 if the channel slope is 0.020 ft/ft.
