Consider a circular price of diameter I m and a trapezoidal channel of maximum depth I m. The trapezoidal channel has a bottom width of I m and side slopes (vertical/horizontal) of 0.25.
a) For a Manning roughness of 0.020 and slope of 0.008 for each channel, calculate water velocity uniform flow at depths of 0.25, 0.50 and 0.75 m.
b) Calculate the wave speeds. (in downstream direction) in each channel for depths of 0.25, 0.50 and 0.75 m.
c) For each wave speed and each channel, calculate the travel time over a length of 300 m.
