Assessing the vulnerability of groundwater resources in semiarid lands of central Argentina
(Springer, 2018)
Groundwater resources in semiarid lands of central Argentina are currently threatened by contamination from agricultural pesticides. The objectives of the present work were: (a) to estimate groundwater recharge on a monthly ...
Assessing interactions between groundwater and surface water in a Pampean stream
(Iwa Publishing, 2016-08)
In the south of Córdoba (Argentina), groundwater from the unconfined aquifer, presents scarce suitability due to high values of salts, sulfates, arsenic and fluorides. This situation makes it necessary to explore other ...
Radon in groundwaters from Guarany aquifer, South America: environmental and exploration implications
(Elsevier B.V., 2002-12-01)
Groundwater and sandstone samples were analyzed for radon in Guarany aquifer, Parana sedimentary basin, South America. The dissolved radon ranged between 3 and 3303 pCi/l, being lognormally distributed, with a modal value ...

Combining remotely sensed actual evapotranspiration and GIS analysis for groundwater level modeling
(Springer, 2019-08-01)
This paper describes a combination of large-scale spatially remote-sensed actual evapotranspiration and geographical information systems of surface runoff to estimate groundwater recharge potential, by water balance, to ...
Some possible evolutionary scenarios suggested by Cl-36 measurements in Guarani aquifer groundwaters
(Pergamon-Elsevier B.V. Ltd, 2014)
MODELING IMPACT OF SMALL MUNICIPAL LANDFILLS ON GROUNDWATER: NATURAL ATTENUATION ISSUES
(BALKEM, A.. A., 2000)
Some constraints on the modelling using the uranium isotopes 238U and 234U for dating groundwaters from Guarany aquifer, South America
(2000-12-01)
Groundwaters from the Guarany aquifer located at the South American continent and sampled at four wells with described geological sections in São Paulo State, Brazil, were chemically and isotopically analysed with two aims: ...
Quasi-Saturated Layer: Implications for Estimating Recharge and Groundwater Modeling
(2019-01-01)
This study presents an extension of the concept of “quasi-saturation” to a quasi-saturated layer, defined as the uppermost dynamic portion of the saturated zone subject to water table fluctuations. Entrapped air here may ...
