The unfinished concrete channel is intended to have a downward slope of 0.002 and sloping sides at 60°. If the flow is estimated to be 100 m³/s, determine the base dimension b of the channel bottom. Take n = 0.014.

Determine the volumetric flow of water through the channel if the depth is y = 1.25 m and the downward slope of the channel is 0.005. The sides of the channel are finished concrete. Take n = 0.012.
