Question

Induced recharge from a nearby stream or river is effective under which of the following condition?

• A. River level $\gt $ Water table
• B. River is dry
• C. Aquifer is confined
• D. Soil is clayey

Hint:

Induced recharge occurs when \[ \boxed{ \text{River level} \gt \text{Groundwater level} } \] so that water flows from the river into the aquifer.

Answer 1

The Correct Option is A

Induced recharge occurs when pumping lowers the groundwater table below the river water level. This creates a hydraulic gradient that causes river water to infiltrate into the aquifer. Hence, \[ \boxed{\text{River level }\gt \text{ Water table}} \] is the correct answer. Therefore, \[ \boxed{(A)} \]
