The purpose of free board in canal is to
The purpose of free board in canal is to
Show Hint
Free board is provided as a safety margin to prevent overtopping of canal banks.
Updated On: May 4, 2026
- Prevent overtopping
- Provide extra storage only
- Reduce seepage loss
- Increase flow velocity
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Free board is the vertical distance between the full supply level of water and the top of the canal bank.
Step 1: In a canal, water level may rise due to waves, sudden inflow or operational variations.
Step 2: If the canal bank height is not sufficient, water may overflow.
Step 3: Free board provides safety margin above the designed water level.
Step 4: This prevents overtopping of canal banks. \[ \boxed{\text{Prevent overtopping}} \]
