​

Answer 1

Answer:water harvesting is the activity of direct collection of rainwater. The rainwater collected can be stored for direct use or can be recharged into the groundwater. Rain is the first form of water that we know in the hydrological cycle, hence is a primary source of water for us.

Khadins and Nadis are two water harvesting structures that are prominent in Rajasthan. Small pits, lakes, earthen dams, sand and limestone reservoirs, and rooftop water collecting units are some of the structures that are used for water harvesting

Answer 2

Answer:

Rainwater harvesting is the collection and storage of rain, rather than allowing it to run off. Rainwater is collected from a roof-like surface and redirected to a tank, cistern, deep pit, aquifer or a reservoir with percolation. Dew and fog can also be collected with nets or other tools.
