Decline in Iran’s groundwater recharge [PDF]
Nature Communications, 2023 Groundwater recharge feeds aquifers supplying fresh-water to a population over 80 million in Iran—a global hotspot for groundwater depletion. Using an extended database comprising abstractions from over one million groundwater wells, springs, and qanats,

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.

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.

Groundwater recharge from heavy rainfall in the southwestern Lake Chad Basin: evidence from isotopic observations [PDF]
Hydrological Sciences Journal, 2021 We examine groundwater recharge processes and their relationship to rainfall intensity in the semi-arid, southwestern Lake Chad Basin of Nigeria using a newly compiled database of stable isotope data (δ2H, δ18O) from groundwater and rainfall.

Using 14C and 3H to understand groundwater flow and recharge in an aquifer window [PDF]
Hydrology and Earth System Sciences, 2014 Knowledge of groundwater residence times and recharge locations is vital to the sustainable management of groundwater resources. Here we investigate groundwater residence times and patterns of recharge in the Gellibrand Valley, southeast Australia, where

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.

Groundwater Recharge Estimation Using WetSpass Modeling in Upper Bilate Catchment, Southern Ethiopia [PDF]
Momona Ethiopian Journal of Science, 2019 The study area, upper Bilate catchment, is strongly dependent on groundwater like other rural catchments in the country. The main objective of this work is to quantify the amount of groundwater recharge in upper Bilate catchment.

Critical reviews in environmental science and technology, 2022 More than two billion people and 40% of global agricultural production depend upon unsustainable groundwater extraction. Managed aquifer recharge (MAR), the practice of strategically recharging water to replenish subsurface storage, is an important ...
