TLDR
In this paper, an estimate of direct groundwater recharge below a region of natural woodland (tiger bush) has been made in south-west Niger using the solute profile technique, which has been collected from a 77 m deep well drug within the study area covered by HAPEX-Sahel (Hydrological and Atmospheric Pilot Experiment), an international large-scale energy, water and carbon balance experiment carried out during the summer of 1992.About:

Approches géochimique et hydrodynamique de la recharge de la nappe du Trarza, Sud-Ouest de la Mauritanie
TL;DR: In this paper, a double approche geochimique (18O, 2H, 14C, 13 C) and hydrodynamique is proposed for recharge of the nappe.

A 70-year groundwater recharge record from sandy loess in northwestern China and its climatic implications
TL;DR: In this paper, a 17m chloride profile was collected from the sandy loess in the northwestern Chinese Loess Plateau, which also lies in the transition zone between desert and loess.

High Recharge Areas in the Choushui River Alluvial Fan (Taiwan) Assessed from Recharge Potential Analysis and Average Storage Variation Indexes
TL;DR: Overall, this study demonstrates that the developed approach can objectively define the RPA parameters and high recharge areas of the Choushui River alluvial fan and the results should serve as valuable references for the Taiwanese government in their efforts to conserve the groundwater quality and quantity of the study area.

The assessment of high recharge areas using DO indicators and recharge potential analysis: a case study of Taiwan’s Pingtung plain
TL;DR: In this paper, the authors used dissolved oxygen (DO) indicators to calibrate the RPA parameters, which improved the correlation coefficient between the DO indicators and computed GRP values from 0.63 to 0.87.

Modalités de recharge d’un aquifère en zone semi-aride : cas de la nappe du Trarza (Sud-Ouest Mauritanie)
TL;DR: The nappe libre de la Trarza as discussed by the authors is contenue dans les sediments du Continental Terminal and du Quaternaire, dans le Sud-Ouest mauritanien, entre le fleuve Senegal au Sud, l’Ocean Atlantique a l ouest and la chaine metamorphique des Mauritanides au Nord and a l'Est.

The use of environmental chloride and tritium to estimate total recharge to an unconfined aquifer
GB Allison,MW Hughes +1 more
TL;DR: In this article, a portion of the Gambier plain underlain by an unconfined aquifer with readily definable hydrologic boundaries has been divided into a number of areas within which soil types have similar hydrological properties, and mean annual recharge has been estimated for each area using both the tritium concentration and the chloride concentration of water within the soil profile.

Estimation of natural groundwater recharge
TL;DR: A review of some of the physical, chemical and isotopic techniques available for estimating groundwater recharge can be found in this article, where the authors propose a model for estimating ground water recharge in arid and semi-arid regions.

Filter-paper method for routine measurement of field water potential
TL;DR: In this paper, a more general use of the filter-paper method for measuring soil-water potential over a very wide range of values is advocated, both for in situ and laboratory situations.

Crust formation on sandy soils in the Sahel I. Rainfall and infiltration
TL;DR: In this article, the causes of crust formation and its effect on the infiltration rate are discussed on untilled soils, and the presence of a crust is a permanent feature on these soils.
