Why is Canal Lining Necessary?

RPSC ACF - 2011: Irrigation Engineering

⭕ (a) To minimize the seepage losses in canal

⭕ (b) To prevent erosion of bed and sides due to high velocities

⭕ (c) To increase the discharge in canal section by increasing the velocity

⭕ (d) All of the above

Explanation: Canal lining provides multiple benefits:

• Prevention of seepage losses
• Prevention of erosion of bed and side slope from high velocity
• Increase in discharge
• Smaller and more economical canal section
• Reduction in water theft
• Quick attainment of full flow capacity
• Rigidity of the channel cross-section

Importance of Canal Lining in Irrigation Engineering

This MCQ tests your understanding of why canal lining is critical in irrigation systems. It enhances efficiency, prevents losses, and ensures structural stability — all essential for effective water distribution.

Other Benefits of Canal Lining

• Reduces maintenance cost
• Improves water delivery schedule
• Increases irrigation efficiency

Conclusion:

The correct answer is All of the above. This concept is frequently asked in competitive exams like RPSC ACF, SSC-JE, and State Engineering Services.
