Recharge and paleo-recharge of groundwater in different basins in Tunisia
Quaternary International, 2020Abstract Assessment of the recharge is of strategic importance for a sustainable development of the aquifer resource, especially in arid and semi-arid areas. This study synthesizes and compares the results of isotope hydrology investigations obtained for different aquifer systems in Tunisia.

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.

Estimating groundwater recharge for Hanoi, Vietnam
Science of The Total Environment, 2019Determining groundwater recharge is in particular in areas with Monsoon rainfall a challenge. Several methods were used to estimate groundwater recharge for the first time ever for the urban area of Hanoi city, Vietnam. Water table fluctuation method (WTF), hydrograph analyses including recession curve displacement, graphical separation, the Automated ...

Groundwater recharge and agricultural contamination
Hydrogeology Journal, 2002Agriculture has had direct and indirect effects on the rates and compositions of groundwater recharge and aquifer biogeochemistry. Direct effects include dis- solution and transport of excess quantities of fertilizers and associated materials and hydrologic alterations relat- ed to irrigation and drainage.

Quantification of groundwater recharge in urban environments
Science of The Total Environment, 2017Groundwater management in urban areas requires a detailed knowledge of the hydrogeological system as well as the adequate tools for predicting the amount of groundwater and water quality evolution. In that context, a key difference between urban and natural areas lies in recharge evaluation. A large number of studies have been published since the 1990s

Groundwater recharge in urban areas
Atmospheric Environment. Part B. Urban Atmosphere, 1990Abstract The two interlinked networks of hydrological pathways in urban areas are described with particular reference to the links with groundwater. As well as reducing direct recharge, urbanization creates new pathways and sources of water for recharge, including leaking water mains, sewers, septic tanks and soakaways.

Man’s Impact on the Groundwater Recharge
2007The water cycle is being constantly and slowly modified since ever by atmospheric, erosion, land cover, and tectonic changes; these changes have been accelerated since activities and growth of mankind (Fig. 6.1) passed a certain threshold number in about the year 1850.

Artificial groundwater recharge, I. Circular recharging area
Journal of Hydrology, 1975Abstract 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, 1975Abstract 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.
