Q78
The main function of a divide wall is to
A.
control the silt entry in the canal
B.
prevent river floods from entering the canal
C.
separate the undersluices from weir proper
AnswerD.
provide smooth flow at sufficiently low velocity
Answer: Option C
Solution
Answer: Option C
Solution:
The main function of a divide wall is to separate the undersluices from the weir proper and provide a smooth flow of water by guiding it efficiently.
It helps in:
- Preventing crosscurrents and turbulence that may interfere with the proper functioning of the undersluices.
- Controlling sedimentation by ensuring that silt-laden water flows towards the undersluices for easy disposal.
- Protecting the structural integrity of the weir by minimizing the impact of high-velocity flows.
