The hydraulic design of permanent gully control structure's determining parameter is:
Show Hint
Hydraulic design of gully control structures mainly depends on runoff rate.
Updated On: May 18, 2026
- Run-off rate
- Dimension of structure
- Structural strength
- Duration

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Permanent gully control structures are designed to safely handle runoff water and prevent further gully erosion.
Step 1: Understand hydraulic design.
Hydraulic design is concerned with the flow of water through or over the structure.
Step 2: Main determining factor.
The important factor for hydraulic design is the rate of runoff that the structure must safely pass. \[ \text{Hydraulic design} \Rightarrow \text{Run-off rate} \]
Step 3: Final answer. \[ \therefore \text{Correct Answer is (A)} \]
