Decline in Iran's groundwater recharge. [PDF]

open access: yesNat 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]

open access: bronzeGroundwater, 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.

Global-scale modeling of groundwater recharge [PDF]

open access: greenHydrology 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]

open access: goldHydrology 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.

Regional assessment of groundwater recharge in the lower Mekong Basin [PDF]

open access: yes, 2017
Groundwater recharge remains almost totally unknown across the Mekong River Basin, hindering the evaluation of groundwater potential for irrigation. A regional regression model was developed to map groundwater recharge across the Lower Mekong Basin where

Microbial community changes induced by Managed Aquifer Recharge activities: linking hydrogeological and biological processes [PDF]

open access: yes, 2019
Managed Aquifer Recharge (MAR) is a technique used worldwide to increase the availability of water resources. We study how MAR modifies microbial ecosystems and its implications for enhancing biodegradation processes to eventually improve groundwater ...

Catchment-scale vulnerability assessment of groundwater pollution from diffuse sources using the DRASTIC method : a case study [PDF]

open access: yes, 2008
The catchment-scale groundwater vulnerability assessment that delineates zones representing different levels of groundwater susceptibility to contaminants from diffuse agricultural sources has become an important element in groundwater pollution ...

Managed Aquifer Recharge as a Tool to Enhance Sustainable Groundwater Management in California [PDF]

open access: yes, 2018
A growing population and an increased demand for water resources have resulted in a global trend of groundwater depletion. Arid and semi-arid climates are particularly susceptible, often relying on groundwater to support large population centers or ...
