Abstract In the region of Stepanek rock glacier (69°19′/69°26′W, 32°55′/32°59′S), in Province Mendoza, Argentina, seasonal hydrochemical monitoring was carried out between 2013 and 2017. This paper describes underground surface water flow, their hydrochemistry, provides an overview how groundwater interacts with glacier. The cryogenic basin study area where hydrological flows originate has a 11.5 km 2 . fills valley its permafrost influences flow. Isotopic analyses ephemeral streams were...
This contribution presents the hydrochemical and isotopic characterisation of phreatic aquifer located in Partido de la Costa, province Buenos Aires, Argentina. In sand-dune barrier geomorphological environment, groundwater is mainly a low-salinity Ca-HCO3 Na-HCO3-type, being general suitable for drinking, whereas continental plain (silty clay sediments), Na-Cl type with high salinity unsuitable human consumption. The composition area ranges from−6.8 to−4.3 ‰ δ18O from−39 to−21 δ2H, showing...
The Quequén Grande River (QGR) is a large catchment (10 000 km2) in the Pampa Plain Argentina. From November 2004 to April 2013, hydrochemical and stable isotopes monitoring program was conducted, which included three sampling stations of monthly composite precipitation, weekly samples two sites along river several groundwater samples. A standard data interpretation initially performed applying statistics, Piper diagrams δ18O versus δ2H diagrams. time evolution values precipitation...
Glacial and periglacial basins contain the largest reserves of fresh water in world. These areas are extremely sensitive to global warming climate change. The dry Andes South America characterized by large areas. This study focuses on isotopic composition hydrochemistry a typical environment Andes, Vallecitos catchment (2400–5500 m a.s.l.), Cordillera Frontal, Argentina. Detailed fieldwork was conducted between 2013 2017 with 240 samples collected for major ions physicochemical parameters,...
Abstract Tritium, a radioisotope of hydrogen, is an ideal tracer for groundwater and surface dating tracking since it part the water molecule. The knowledge history tritium in precipitation recharge key link calculation age. However, records are usually sparse discontinuous, especially regions like South America, often need to be reconstructed. To solve this problem, different reconstruction methods input function have been analysed compared. Clustering Global Network Isotopes Precipitation...
El estudio de la composicion isotopica precipitacion estacion Buenos Aires fue vital importancia para complementar interpretacion algunos de los sistemas hidrologicos pampeanos. contenido isotopico (2H, 18O y 3H) las lluvias se registra desde 1978 en Ciudad Universitaria ciudad de Buenos Aires, que pertenece a Red Nacional Colectores Argentina la Global Network for Isotopes in Precipitation. La del agua de lluvia Buenos Aires responde un promedio anual ponderado δ18O= -5,5, δ2H=-30 ha...
Stable isotopes and electrical conductivity in groundwater were used as natural tracers to adjust the hydrogeological conceptual model one of largest catchments within inter-mountainous Pampa plain, Argentina. Geostatistical tools define that best fitted spatial distribution each tracer, information was obtained areas where there a lack data. The conventional isotopic analysis allowed identification three groups with different fingerprints. One group containing 56 % total samples suggested...
Abstract 3 H enters the hydrologic cycle after oxidizing in 1 HO molecule and it constitutes a very useful tracer for hydrological studies. One of these applications is streamflow component separation, which provides information to understand cycle. This application based on fact that contents precipitation (runoff) tend be markedly higher than those groundwater (baseflow) because decreasing activity last as consequence radioactive decay. The main objective this paper test hydrograph...
Abstract In Córdoba Province, Argentina, the population uses groundwater from confined aquifer systems (CASs) for different activities. Therefore, it is necessary to carry out comprehensive studies in order plan more sustainable use considering that renewal times can be of several thousands years. The objective this research evaluate age aquifers based on hydraulic and isotopic methods. CASs present variable extension, are multilayered formed by thin (4–6 m) sand-pebble lenses, linked...
