Horizontal rectangular channel (4 m) wide is carrying a discharge of 20 m3/s at a depth of 2.5 m. If the channel width is reduced linearly from 4 m to 3 m in length of 5 m, determine the flow depth at the location where the channel width is 3.5 m. Assume there are no losses in the contraction
A rectangular channel is 4 m wide, and it reduces to 2 m through a hydraulic structure. Assuring the transition to be horizontal and the flow to be frictionless determine the water surface elevations upstream of the constriction when the specific energy at the constriction is 6 m. Assume choking occurs, hence critical flow equations are applicable. Note: Hand written solution is not allowed.
A flow of 30 m3 /s occurs in a trapezoidal channel having a base width of 3 m, side slopes 1 vertical to 2 horizontal. Determine the critical depth, yc.
Stationary water overflows from a reservoir over a broad crested spillway weir 5m wide. The spillway converges and terminates in a channel 3m wide the bed of which is 2m lower than the crest of the weir. Assuming critical flow over the crest and Cd = 1, determine the depth of the flow in the channel when the surface level of the reservoir is 0.2 m above the crest of the spillway
In the rectangular 4-meter-wide canal, uniform flow occurs with the 20 + 2 m3/s discharge at a depth of 2.0 meters. if a hump of the height of 30 cm is placed in the bottom of the canal, calculate the water depth on the hump. Neglect head loss over the hump.
There is a rectangular channel that will be excavated downstream of a dam after a stilling basin both with a width of 15 meters. The depth of the wather flow upstream of the dam is 4.27 meters and the discharge flow above the dam is 112.5 cubic meters per second. the channel wil be excavated in earth and n = .o25 and maintains a uniform flow depth under a subcritical flow regime. I need to determine 1. the bottom channel slope needed in the downstream channel and 2. the length of the stilling basin if the dissipation stucture starts at dissipated along the structure. The design should consider that the flow depth at the end of the still basin is similar to the flow depth in the channel. For a more realistic approach in the design, the head loss between the station upstream of the dam and the station at the beginning of the still basin is 10% of the velocity head observed at the beginning of the basin

A rectangular channel 6 m wide has 1.50 m depth of water flowing with a mean velocity of 0.75 m/s. a standard sharp-crested weir increases the depth in the channel approach to 2.50 m. when the flow in the channel is 6.75 m³/s and considering the velocity of approach, find the height of the weir.
