Question

Which of the following is an attempt towards water harvesting?
A) Building of check dams along the seasonally flooded gullies
B) Deforestation
C) Providing irrigation in the fields
D) None of the above

Answer 1

Hint: Water harvesting is the process of collecting rainstorm-generated runoff from a specific region (a catchment) in order to provide water for human, animal, or crop consumption.

Complete answer:
Rainwater harvesting is the process of collecting and storing rainwater rather than letting it flow off. Rainwater is gathered from a roof-like surface and guided to a tank, cistern, deep pit, aquifer, or reservoir using percolation, where it seeps down and replenishes the groundwater supply.

The construction of check dams along the gullies that are flooded seasonally is an attempt at water harvesting. Instead of allowing runoff to cause erosion, it collects it for constructive purposes. Water harvesting is a directly productive technique of soil and water conservation in semi-arid drought-prone locations where it is already practised. This captured water might be kept and re-injected into the groundwater system.

Rainwater harvesting is one of the simplest and oldest methods of self-supply of water for families, as well as residential and household-scale enterprises, which are typically self-financed. Larger systems for schools, hospitals, and other buildings, on the other hand, can incur costs that can only be covered by owners, companies, and government entities.

Therefore the correct answer is option ‘A’.

Note: Nets and other items can also be used to gather dew and fog. Rainwater harvesting varies from stormwater harvesting in that it collects rainwater from roofs rather than creeks, drains, roadways, or other land surfaces. Watering gardens, animals, irrigation, home use with adequate treatment, and domestic heating are just a few of its applications. The water collected might be used for long-term storage or groundwater replenishment.
