Problem 2. A 25-foot wide rectangular channel with Manning’s nof 0.025 is carrying 5000 cfs. The slope of the channel is 0.05%(0.0005 ft/ft). At a specific point, the slope changes abruptly to5%. Using the direct step method, calculate the profile upstream ofthe break in slope, extending upstream to a point where the depthis within 5 percent of normal depth. (That means the final depth inyour direct step method is between 0.95 and 1.05 times normaldepth.) Classify the flow profile (M-1, S-1, etc.).
