A rectangular channel (n = 0.020) is to be 3.0 m wide. If a discharge of 3.00 m3/s is to be passed with the channel having an efficient section, what longitudinal slope is to be provided?
A 12-ft-wide rectangular channel conveys 3,030 cfs. Determine the normal and critical depths for the concrete channel (1% slope). Also determine the flow classification (critical, supercritical, or subcritical) when the channel flows at normal depth.
2. A 2.5 m wide rectangular channel conveys m wide rectangular channel conveys water at a normal depth of 2 m. In a part of the channel, the channel width is expanded to 5 m. The local energy loss due to this expansion is about 10% of the upstream velocity head. If the channel slope is 0.03% and the Manning roughness coefficient is about 0.012, calculate the water depth over this transition and show the situation with a simple sketch.
Water flows through a rectangular channel 7.3 meter wide, at a rate of 3.1 m^3/s. with a depth of 3 meters. The channel is lined with rough concrete and has a slope of 0.075 %. Calculate the critical depth, and normal depth and classify the slope. Manning's number for the channel is 0.014.
Water flows down a rectangular channel that has a width of 2.2 m, a Manning's n of 0.019 and a slope of 1 in 200. Calculate the discharge in the channel when the depth of flow is 0.5 m, 1.0 m, 2.0 m, and 4.0 m.

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...
