7. Given the water surface (M2) profile, channel slope is MILD. Drawdown of the water surface occurs with approach to the free overfall For a 90-degree v-notch channel geometry, bed slope 0.0001, a Manning-n of 0.01 and a flow of 0.425 m'/s find (a) the Froude number and flow regime and (b) Critical depth near the free overfall (c) How far upstream does the flow become uniform (d) What is the water depth at this upstream location? M2 NDL DL...

Water discharging into a 12-m-wide rectangular horizontal channel from a sluice gate is observed to have undergone a hydraulic jump. The flow depth and velocity before the jump are 0.9 m and 9 m/s, respectively. Determine (i) Froude number before the hydraulic jump. Is it subcritical, critical, or supercritical flow? (4 points) (ii) the flow depth and the Froude number after the jump. Is it subcritical, critical, or supercritical flow? (9 points) (iii) the head...
