At a certain location, the depth of flow in a wide rectangular channel is 0. 73 m. The channel discharge is 1.6 m3/sec per unit width, the bottom slope is 0.001, and Manning's coefficient is 0.0 15. Determine the channel and flow classification (M-1, S-2, etc.) and explain your supporting logic. Will / the depth increase or decrease going upstream? Using the standard step method (one step), determine .\f.. "\ the depth of flow 1 2 m upstream.
