cgwb.gov.in3. Ground Water Resources Availability: Rainfall is the major source of ground water recharge in India, which is supplemented by other sources such as recharge from canals, irrigated fields and surface water bodies. A major part of the ground water withdrawal takes place from the upper unconfined aquifers, which are also the active
Basic Concepts of Groundwater Hydrology
groundwater.ucdavis.eduof groundwater flow is greater with higher hydraulic conductivity, even if the hydraulic gradient is the same. The hydraulic conductivity of sandy or gravelly aquifers typically ranges from 100 to 10,000 gallons per day (gpd) per square foot (approximate equivalent: 10 to 1,000 ft/day). On the other hand, the hydraulic con-

Some aquifers are small, while others span tens of thousands of square miles. The Middle Claiborne Aquifer is one of the latter. It underlies portions of eight States in the Missis-
