The down stream sloping glacis of the Hydraulic structure is made in such a way to form automatically the _____________ and dissipate the surplus energy of flowing water?
Correct answer: B. Hydraulic jump
- A. Afflux
- B. Hydraulic jump
- C. Pond level
- D. HFL
Explanation
The downstream glacis is shaped to create a hydraulic jump, which changes high-velocity flow into a deeper, slower flow and dissipates excess energy. Afflux is the rise in upstream water level, not an energy-dissipation structure.
