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:

Spatial Distribution of Groundwater Production and Development Potential in the Volta River basin of Ghana and Burkina Faso
Nicola Martin,Nick van de Giesen +1 more
TL;DR: In this paper, the authors evaluate the contribution of continuing groundwater resources development on the improvement of water supply and assess the impact of increasing abstraction on the overall water budget, the spatial distribution of groundwater production for rural and urban water supply in the Volta River basin in West Africa is quantified and compared to population densities, groundwater recharge, and groundwater potential.

Unsaturated zones as archives of past climates: toward a new proxy for continental regions
W.M. Edmunds,S. W. Tyler +1 more
TL;DR: Natural chemical and isotopic tracers contained in unsaturated-zone moisture profiles are being developed as potential new archives for reconstructing recharge history, as well as palaeoclimatic or palaeobotanical conditions over time scales ranging from 20-120,000 years.

Soil Water Balance
TL;DR: In this paper, the importance of spatial redistribution of water in the dynamics and functioning of tiger bush bands is discussed, where the authors define the minimum common characteristics necessary for the existence of banded vegetation spatial structure, including a semiarid climate, high-intensity rainfall, and a gentle slope.

Deep infiltration through a sandy alluvial fan in semiarid Niger inferred from electrical conductivity survey, vadose zone chemistry and hydrological modelling
Sylvain Massuel,Guillaume Favreau,Marc Descloitres,Yann Le Troquer,Yves Albouy,Bernard Cappelaere +5 more
TL;DR: A detailed geophysical and geochemical survey was conducted on a large, representative mid-slope fan (6 × 6 × 1.5 m) in semiarid southwestern Niger as discussed by the authors, where a physically-based, 2D distributed hydrologic model was used to estimate the amount of surface water loss by infiltration for the 1992-2002 period.

A 700-year history of groundwater recharge in the drylands of NW China
TL;DR: In this paper, a 700-year semi-quantitative history of diffuse groundwater recharge in the Badain Jaran Desert (Inner Mongolia) is proposed on the basis of solute data from multiple unsaturated zone groundwater profiles using mass balance of chloride.

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.
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.

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.
