Water is flowing at a rate of 15 m3/s in a triangular channel with a 2.5 m water depth, 1:1 side slope, and 0.003 m/m bed slope. The representative roughness element of the boundary is 0.25 in. If the observed maximum velocity is 3.8 m/s, compute the vertical velocity profile using the rough law and the 1/7 power law.
