please show all the steps thank you 2. Water flowing at the normal depth in a rectangular concrete channel that is 12 m wide encounters an obstruction, causing the water level to rise above the normal depth at the obstruction and for some distance upstream. The water discharge is 126 m3/s, and the channel bottom slope is 0.00086. If the depth of water just upstream from the obstruction (yo) is 4.55 m, find the distance upstream to the point where...
