Decline in Iran's groundwater recharge. [PDF]
Nat Commun, 2023 Abstract Groundwater recharge feeds aquifers supplying fresh water to a population over 80 million in Iran – a global hotspot for groundwater depletion. Using a rich database comprising abstractions from about one million groundwater wells, springs and qanats, from 2002 to 2017, here we show a significant decline of around -3.8 mm/yr in the ...

Estimating groundwater recharge [PDF]
Eos, Transactions American Geophysical Union, 2011 Groundwater recharge is the entry of fresh water into the saturated portion of the subsurface part of the hydrologic cycle, the modifier “saturated” indicating that the pressure of the pore water is greater than atmospheric. Briefly stated, recharge is downward flux across the water table.

Distributed groundwater recharge potentials assessment based on GIS model and its dynamics in the crystalline rocks of South India [PDF]
Scientific Reports, 2021 Extensive change in land use, climate, and over-exploitation of groundwater has increased pressure on aquifers, especially in the case of crystalline rocks throughout the world.

Global-scale modeling of groundwater recharge [PDF]
Hydrology and Earth System Sciences, 2007 Abstract. Long-term average groundwater recharge, which is equivalent to renewable groundwater resources, is the major limiting factor for the sustainable use of groundwater. Compared to surface water resources, groundwater resources are more protected from pollution, and their use is less restricted by seasonal and inter-annual flow variations.

An approach to identify urban groundwater recharge [PDF]
Hydrology and Earth System Sciences, 2010 Abstract. Evaluating the proportion in which waters from different origins are mixed in a given water sample is relevant for many hydrogeological problems, such as quantifying total recharge, assessing groundwater pollution risks, or managing water resources.

Evaluation of drought impact on groundwater recharge rate using SWAT and Hydrus models on an agricultural island in western Japan [PDF]
Proceedings of the International Association of Hydrological Sciences, 2015 Clarifying the variations of groundwater recharge response to a changing non-stationary hydrological process is important for efficiently managing groundwater resources, particularly in regions with limited precipitation that face the risk of water ...

Groundwater and baseflow drought responses to synthetic recharge stress tests [PDF]
Hydrology and Earth System Sciences, 2021 Groundwater is the main source of freshwater and maintains streamflow during drought. Potential future groundwater and baseflow drought hazards depend on the systems' sensitivity to altered recharge conditions.

Predicting groundwater recharge for varying land cover and climate conditions – a global meta-study [PDF]
Hydrology and Earth System Sciences, 2018 Groundwater recharge is one of the important factors determining the groundwater development potential of an area. Even though recharge plays a key role in controlling groundwater system dynamics, much uncertainty remains regarding the relationships ...
