Q: Select the option that is appropriate regarding the following two statements labelled Assertion and Reason. Assertion: In lined canals, the increased velocity eliminates the possibility of silting in the canal bed. Reason: Canal lining provides a smooth and stable surface and thus, the velocity of the flow can be increased
  • A. Both Assertion and Reason are true, but Reason is not the correct explanation of Assertion
  • B. Both Assertion and Reason are true and Reason is the correct explanation of Assertion
  • C. Assertion is true, but Reason is false.
  • D. Both Assertion and Reason are false.
Correct Answer: Option B - Advantages of Canal lining– • Prevents water seepage through surface of canal. • Increases discharge carrying capacity of the canal. • Silting is prevented as velocity is increased. • Increase available head for power generation due to flatter gradient.
B. Advantages of Canal lining– • Prevents water seepage through surface of canal. • Increases discharge carrying capacity of the canal. • Silting is prevented as velocity is increased. • Increase available head for power generation due to flatter gradient.
