Detailed explanation-1: -Rainwater is collected from a roof-like surface and redirected to a tank, cistern, deep pit (well, shaft, or borehole), aquifer, or a reservoir with percolation, so that it seeps down and restores the ground water. Dew and fog can also be collected with nets or other tools.

Detailed explanation-2: -Traditionally, this involves harvesting the rain from a roof. The rain will collect in gutters that channel the water into downspouts and then into some sort of storage vessel.

Detailed explanation-3: -1. Rooftop rainwater harvesting: This type of rainwater harvesting system is quite popular and the water can easily be collected from the terrace of the building or the courtyards. In the rooftop rainwater harvesting system, the roof becomes the catchment area where the rainwater is stored.

Detailed explanation-4: -The correct option is B rainwater harvesting. The method of collecting and storing rainwater for later use, rather than allowing it to run off is called rainwater harvesting.

Detailed explanation-5: -Surface runoff harvesting. In this method, rainwater flows away as surface runoff and can be stored for future use. Groundwater recharge. Groundwater recharge is a hydrologic process where water moves downward from surface water to groundwater. 05-Nov-2019
