Question

Which of the following is not a direct method of discharge measurement in a stream?
1. Velocity area method using current meter 
2. Velocity area methods using floats
3. Dilution method
4.  Slope area method

Answer 1

Correct Answer - Option 4 :  Slope area method

Explanation

The classification of discharge measurement methods are:

Direct Method

1) Area velocity method

2) Dilution method

3) Ultrasonic method

4) Moving boat method

5) Electromagnetic method

Indirect method

1) Slope area method

2) Q – Measuring structure [weir, notch etc.]

∴ Slope Area method is not a direct method of discharge measurement
