Potential groundwater contribution to Amazon evapotranspiration [PDF]

Hydrology and Earth System Sciences, 2010
Abstract. Climate and land ecosystem models simulate a dry-season vegetation stress in the Amazon forest, but observations do not support these results, indicating adequate water supply. Proposed mechanisms include larger soil water store and deeper roots in nature and the ability of roots to move water up and down (hydraulic redistribution), both ...

Dissolved noble gases and stable isotopes as tracers of preferential fluid flow along faults in the Lower Rhine Embayment, Germany [PDF]

, 2015
Groundwater in shallow unconsolidated sedimentary aquifers close to the Bornheim fault in the Lower Rhine Embayment (LRE), Germany, has relatively low δ2H and δ18O values in comparison to regional modern groundwater recharge, and 4He concentrations up to

Groundwater potential in Sierra Leone [PDF]

Acque Sotterranee - Italian Journal of Groundwater, 2018
Groundwater is a major source of safe drinking water  throughout Africa. Despite this, little quantitative information on aquifers potential is known in many countries. Sierra Leone has annual precipitation rates of as much of 5000 mm/yr and a capillary net of surface streams, but the hydrogeological aspect was never taken into serious consideration ...
