Estimation of specific yield and its variability by electrical resistivity tomography
(American Geophysical Union, 2018-10)
Specific yield (Sy) is defined as the average volume of water that can be drained, per unit surface of aquifer per unit drop of head. This parameter is of critical relevance for groundwater resources assessment, but its ...
Estudio preliminar del origen del agua del Valle de Uspallata y de su contribución al río Mendoza mediante técnicas isotópicas e hidroquímicas: Mendoza, ArgentinaPreliminary study of water origin in the Uspallata valley and its contribution to the Mendoza river with isotopic and hydrochemical techniques: Mendoza, Argentina
(Instituto Geologico y Minero de España, 2021-01)
El Valle de Uspallata está situado en la Provincia de Mendoza (Argentina), a unos 1900 m snm. Con dirección norte-sur y unos 20 km de longitud, constituye un valle intermontano localizado entre la Precordillera y la ...
Characterization of processes and mechanisms controlling ground water salinization in the Algerian Sahara
(Springer, 2020-09-09)
This study assesses mechanisms responsible for the aquifer salinization in the Guerrara oasis, in southern Algerian Sahara. Here, underground hydrological resources are indispensable for the local inhabitants. To determine ...
Identifying the factors that determine ecosystem services provision in Pampean agroecosystems (Argentina) using a data-mining approach
(Elsevier, 2018-03)
Ecosystem services (ES) have become a key concept in the assessment of natural resources, as a way to connect human well-being and ecosystems degradation. However, ES quantification is considered a basic problem because ...
Investigating nitrate dynamics in a fine-textured soil affected by feedlot effluents
(Elsevier Science, 2016-10)
Feedlots concentrate large volumes of manure and effluents that contain high concentrations of nitrate, among other constituents. If not managed properly, pen surfaces run-off and lagoons overflows may spread those effluents ...
Tracing Water Sources and Fluxes in a Dynamic Tropical Environment: From Observations to Modeling
(Frontiers Media, 2020-11)
Tropical regions cover approximately 36% of the Earth’s landmass. These regions are home to 40% of the world’s population, which is projected to increase to over 50% by 2030 under a remarkable climate variability scenario ...

Arsenic effects on some photophysical parameters of Cichorium intybus under different radiation and water irrigation regimes
(Pergamon-Elsevier Science Ltd, 2018-08)
The presence of arsenic (As) in groundwater is a major problem in several parts of Latin America. In the present work, non-destructive approaches to monitor the effects of As on plants of Cichorium intybus, an herbaceous ...
Nitrogen application mitigates drought-induced metabolic changes in Alhagi sparsifolia seedlings by regulating nutrient and biomass allocation patterns
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2020-10)
Groundwater and its associated nutrients sustain the establishment and persistence of phreatophytes. Rapid root elongation immediately after germination is vital for desert species to access deep water sources to avoid ...
Origin, distribution, and geochemistry of arsenic in the Altiplano-Puna plateau of Argentina, Bolivia, Chile, and Perú
(Elsevier Science, 2019-05)
Elevated concentrations of arsenic in water supplies represent a worldwide health concern. In at least 14 countries of South America, high levels have been detected relative to international standards and guidelines. Within ...
