This study uses an integrated approach to characterize the dynamic evolution of power-producing high-enthalpy geothermal system Lahendong, North-Sulawesi, Indonesia. Lahendong has two primary reservoirs, southern and northern, which have been utilised for electricity production more than twenty years. The main focus this is characterisation heat mass flows in with respect geological structures ...

A methodology was developed and applied to the Tindouf basin (south-western Algeria) understand hydrogeology of a complex aquifer system with limited number data, identify favorable areas for design building new wells, know whether there is still current recharge these aquifers. The principal components analysis (PCA), diagram deuterium versus oxygen-18, equilibrium diagrams Mg/Na Ca/Na were te...

This contribution presents the hydrochemical and isotopic characterisation of the phreatic aquifer located in the Partido de la Costa, province of Buenos Aires, Argentina. In the sand-dune barrier geomorphological environment, groundwater is mainly a low-salinity Ca-HCO3 and Na-HCO3-type, being in general suitable for drinking, whereas in the continental plain (silty clay sediments), groundwate...
