Groundwater Recharge Technologies

Journal of Crop Improvement, 2009
Groundwater is declining at a very fast rate in the central plain region of Indian Punjab, comprising about 80% area of the state. Consequently, centrifugal pumps, which were earlier being used by farmers for pumping groundwater, are being replaced by costly submersible pumps.

Estimating Groundwater Recharge

2010
Understanding groundwater recharge is essential for successful management of water resources and modeling fluid and contaminant transport within the subsurface. This book provides a critical evaluation of the theory and assumptions that underlie methods for estimating rates of groundwater recharge.

Artificial groundwater recharge, I. Circular recharging area

Journal of Hydrology, 1975
Abstract Artificial groundwater recharge is of increasing importance as an essential component of water-management programs. The fluctuation of the water table in response to recharge depends on the size and shape of the recharging area, on the duration and the type of variation of the recharge rate, and on the hydraulic and geometric parameters of ...

Artificial groundwater recharge, II. Rectangular recharging area

Journal of Hydrology, 1975
Abstract The nonlinear, partial-differential equation characterizing the unsteady flow in an unconfined aquifer receiving uniform vertical recharge from a rectangular spreading basin is solved numerically. The method of solution consists of the alternating-direction implicit scheme with an inhomogeneous grid spacing.

Groundwater Recharge Concepts

1988
Groundwater recharge is usually considered a process of water movement downward through the saturated zone under the forces of gravity or in a direction determined by the hydraulic conditions. In a broader sense the process of recharge is more complicated.
