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.
