Question

Assertion A: The distance from the centre of the well to the outer limit of the cone of depression is known as radius of influence.
Reason R: Radius of influence depends on the pumping rate, length of pumping period, aquifer characteristics, slope of the water table and recharge in the zone of influence of the well.
In light of the above statements, choose the most appropriate answer from the options given below:

• A. Both A and R are correct and R is the correct explanation of A
• B. Both A and R are correct but R is NOT the correct explanation of A
• C. A is correct but R is not correct
• D. A is not correct but R is correct

Hint:

Radius of influence increases with:
- Higher pumping rate
- Longer pumping period
- Lower aquifer transmissivity

Answer 1

The Correct Option is A
