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.
Let's analyze the validity of each statement and their relationship:
- Assertion Analysis:
- The assertion that increased velocity in lined canals eliminates the possibility of silting in the canal bed is true. When the velocity of the water flow is high enough, it prevents the settlement of sediment particles, thus reducing or eliminating silting.
- Reason Analysis:
- The reason that canal lining provides a smooth and stable surface and thus increases the velocity of the flow is also true. The smooth surface of the lining reduces friction and resistance, allowing water to flow more swiftly.
- Relationship Between Assertion and Reason:
- Both the assertion and reason are true, and the reason correctly explains the assertion. The smooth and stable surface provided by canal lining indeed increases the velocity of the water flow, which in turn helps in preventing silting by carrying sediment particles away.
