For which of the following conditions, the hydraulic jump formation will be perfect and it will be formed at the toe of the spillway at all discharges ? (where J. H. C.-Jump Height Curve              T. W. C.-Tail Water Curve)

For which of the following conditions, the hydraulic jump formation will be perfect and it will be formed at the toe of the spillway at all discharges ? (where J. H. C.-Jump Height Curve              T. W. C.-Tail Water Curve) Correct Answer <span style="">J. H. C. and T. W. C. coincides at all discharges</span>

Explanation:

When J.H.C. coincides with T.W.C., the hydraulic jump will form at the toe of the spillway. It is the most ideal condition. A jump will form for all discharges.

When J.H.C. lies below T.W.C., the hydraulic jump will form but dissipate less energy.

When J.H.C. lies above T.W.C., the water will form a jump and may shoot out of a bucket.

Which of the following statements are true with regard to energy dissipation below a dam? (i) If the upper conjugate depth of a hydraulic jump is below the tailwater, little energy will be dissipated (ii) An upturned bucket will protect the dam from scour by moving material toward the dam. (iii) A secondary dam may increase tailwater height, thereby causing a hydraulic jump to form at the toe of the main dam. (v) A slopping apron above streambed level may be used to control the hydraulic jump so that it occurs on the apron. 
Which of the following assumptions is/are made in the analysis of hydraulic jump? 1. It is assumed that before and after jump formation the flow is essentially two-dimensional and that the pressure distribution is hydrostatic. 2. The length of the jump is small so that the losses due to friction on the channel floor are small and hence neglected. 3. The channel floor is horizontal or the slope is so gentle that the weight component of the water mass comprising the jump is very high.
When the tail-water depths in the river downstream of a spillway are quite low such that the tail-water curve at all discharges lies below the post jump depth curve, then the energy dissipation can be affected best by ___________________
