Estimation of rainfall inputs and direct recharge to the deep unsaturated zone of southern Niger using the chloride profile method
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:

Groundwater and climate change in Africa : review of recharge studies
Helen Bonsor,Alan MacDonald +1 more
TL;DR: A review of recharge studies was conducted as part of a one year DFID-funded research programme, aimed at improving understanding of the impacts of climate change on groundwater resources and local livelihoods as discussed by the authors.

Evaluating Groundwater Storage Change and Recharge Using GRACE Data: A Case Study of Aquifers in Niger, West Africa
Sérgio Augusto Barbosa,Sarva T. Pulla,Gustavious P. Williams,Norman Jones,Bako Mamane,Jorge Sánchez +5 more
TL;DR: In this paper , the authors present a study of groundwater storage changes and recharge in Southern Niger, computed using data from NASA Gravity Recovery and Climate Experiment (GRACE) mission, and show that there is little change in groundwater storage from 2002 to 2010, but a steep rise in storage from 2010 to 2021, which can partially be explained by a period of increased precipitation.

Local recharge processes in glacial and alluvial deposits of a temperate catchment.
Federico A. Fragalà,Geoff Parkin +1 more
TL;DR: In this paper, the authors demonstrate that the composition and structure of Quaternary deposits and topography significantly influence rates of recharge and distribution of diffuse agricultural pollution at the hillslope scale.

Groundwater Diffuse Recharge and its Response to Climate Changes in Semi-Arid Northwestern China
TL;DR: In this article, the authors obtained three chloride profiles of the unsaturated zone in the desert/loess transition zone of northwestern China and reconstructed the groundwater recharge variations over the last 11, 21, and 37 years, respectively, using the generalized chloride mass balance (GCMB) method.

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.
BookDOI
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.
Journal ArticleDOI
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.
Journal ArticleDOI
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.
