Question

Water course is any channel which is supplied with water from a canal but which is not maintained at the cost of the Government. The carrying capacity of water course generally varies:

• A. 10 to 30 litres per second
• B. 30 to 120 litres per second
• C. 0.75 to 5.5 cubic meter per second
• D. 4.0 to 8.5 cubic meter per second

Hint:

Water course capacity: 30-120 L/s.
Distributary: 120-1000 L/s.
Main canal: \(>\) 1000 L/s.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
A water course is a small channel that carries water from a canal to fields.
It has a specific capacity.

Step 2: Key Formula or Approach:
No specific formula.
Need to know the typical carrying capacity of a water course.

Step 3: Detailed Explanation:
A water course generally has a carrying capacity of 30 to 120 litres per second.
This is sufficient for small to medium-sized fields.
Larger capacities are for main canals and distributaries.
Thus, the correct range is 30 to 120 litres per second.

Step 4: Final Answer:
The carrying capacity of a water course generally varies from 30 to 120 litres per second.
Hence, the correct option is (B).
