Unit 3 ground water lect-5

The document discusses various methods of artificial groundwater recharge including spreading methods, flooding, basin method, artificial channel method, natural channel method, field pits, percolation tanks, ponds, and check dams. It provides details on how each method works and suitable conditions for each. The key purposes of artificial recharge are to increase groundwater storage during monsoons, increase soil fertility, improve existing groundwater quality, reduce seawater intrusion, store water for summer use, and increase water supply where other sources are not available. Factors like topography, soil characteristics, slope, and climate must be considered when selecting a recharge method.
