QUESTION: 3

### The crest profile of an ungated ogee spillway, downstream of the apex under a design head Hd, can be expressed as (y/Hd) = K(x/Hd)n Where the coefficients K and n, for a vertical upstream spillway would, respectively, be

Solution:
QUESTION: 4

At the foot of a spillway, the jump rating curve is below the tailwater curve at low flows and above it at high flows. The suitable type of energy dissipator for this situation is

Solution:

Solution:
QUESTION: 10

A ski-jump bucket is generally used as an energy dissipator when the tail water

Solution:

The ski jump bucket type of an energy dissipator can be used for energy dissipation when the tail water depth is insufficient or low at all discharges. The ski jump bucket type of an energy dissipator requires sound and rocky river bed, because, a part of the energy dissipation takes place 'by impact, although some of the energy is dissipated in air by diffusion and aeration.
