Environment & Ecology question from Panchayat Secretary (VLW) exam, 2025 by JKSSB
What happens when runoff on the ground is collected and allowed to be absorbed?
Last updated Jun 5, 2026
Correct Answer:
Option D —
Ground water gets recharged
When surface runoff (rainwater that flows over the ground) is collected, slowed down, and allowed to infiltrate the soil, it moves downward through the soil layers to replenish the underground aquifers. This process is fundamentally known as groundwater recharge or rainwater harvesting.
Why the other options are secondary:
While the land does temporarily become wet (A) and trees benefit from the soil moisture (B), these are localized, immediate effects.
While it can reduce urban flooding (C) if managed properly at a large scale, the primary, direct geological consequence of allowing runoff to soak into the ground is the replenishment of the water table.
