A trapezoidal channel with 3.0m bottom width and 1:1 side slope carries a discharge of 10 m³/s at a slope of 12 cm/km. A hydraulic jump is formed in the channel with an initial depth of 0.6m. Calculate the momentum function, the critical depth, and the conjugate depth. Y₁ = 0.6m Y₂ B Fig. 5 Hydraulic jump and channel's cross-section y k b = 3.0m

A horizontal channel with a trapezoidal cross-section has a bottom width of 5 m, sidewall slope of 1V:2H, and discharge of Q = 10.85 m³/s. The water level was kept constant at the gate to 0.25 m to form a hydraulic jump in the channel. The conjugate depth based on the graphical method (Figure 6-7) is: Select an answer and submit.

A sluice gate at the base of a large reservoir is raised 1.7 m (see Figure below), and the waterdischarges through this 5.0 m-wide rectangular orifice into a rectangular channel of the samewidth. If a hydraulic jump forms in the channel, determine:a. velocity at the opening of the sluice gateb. Froude number of the flow under the sluice gate, and prove that it is supercriticalc. conjugate depths, d1 and d2d. height of the hydraulic jump (d2-d1)

Question 3 a. Uniform water flow in a wide brick channel of slope 0.02° moves over a 10 cm bump as shown below in Figure 3.1. A slight depression in the water surface results. If the minimum depth over the bump is 50 cm compute i. the velocity over the bump; and ii. the flow rate per metre of width. V1 10 cm bump y, = 50 cm 0.02° Figure 3.1. Channel with bump

If h2 > hi: a. aquifer water is flowing from the Well A location towards the Well B location b. the direction of aquifer water flow cannot be determined c. the hydraulic gradient can be calculated using the head difference between the wells d. none of the above 50. Since 2007, what is the trend in the depth to the water level measured for the three USGS groundwater Texas stations examined in the homework assignment? a. no changes in the depth to the water have occurred b. the depth to the water has increased at all stations c. data was not available for all of the sites d. none of the above

6. A trapezoidal cross-section with bottom width, B = 3 m, and sidewall slope, 0 = 60° is shown as below. When flow depth is y0 =2.5 m, please determine 1) flow section area, A, 2) hydraulic radius, R, and 3) hydraulic depth, D. Furthermore, if the mean velocity at this cross-section is V = 1.5 m/s, please determine 4) Reynolds number, Re, =1.14*103, 5) Froude number, Fr, of this channel flow, and 6) specify the flow condition (Is this a subcritical, critical, or supercritical flow?).
