Problem 10.46
Uniform flow occurs in a long rectangular channel of width b, S0 = 0.0163 and n = 0.012. The channel is altered by raising the channel bottom by z for a short distance. The alteration is intended to act as a "smooth transition region" so that losses can be considered negligible. Determine what changes take place due to the presence of the transition. In your analysis include all relevant rapidly varied flow calculations, identify any gradually varied flow profiles, and sketch the water surface and energy grade line.
