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:

Mechanisms and Rates of Groundwater Recharge at Timbuktu, Republic of Mali
Gunnar Jacks,Matallah S. Traoré +1 more
TL;DR: The mechanisms and rate of groundwater recharge were assessed for the uppermost aquifer used for water supply by local settlements in the area surrounding Timbuktu, Republic of Mali, using chloride budgets as discussed by the authors.

Using tracer tests to estimate vertical recharge and evaluate influencing factors for irrigated agricultural systems
TL;DR: In this article, a bromide solution was applied below root regions to trace infiltration in the vadose zone beneath irrigated agricultural fields and non-irrigated woodlands at both piedmont plain and alluvial and lacustrine plain areas (Hengshui) in the NCP.
Journal ArticleDOI
Sensitive analysis of ground recharge estimation model, for semiarid areas
TL;DR: In this paper, a modified model has been improved by in-site experiment (soil chloride mass balance) tested in some selected sites in Sidi Slimane River located in the region of Djelfa at 300 km from Algiers (Algeria).

The Physics of Atmospheric Interaction
C. Lloyd,Sylvia Oliver +1 more
TL;DR: The first integrated forest micrometeorology experiment at Thetford provided a blueprint for the forest experiments found in CarboEurope, whereas the intensive measurement programme in Amazonia in 1984 showed that remote and hostile terrains could be successfully investigated.

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.
