Modelo hidrogeológico conceptual del Sistema Acuífero Guaraní (SAG): una herramienta para la gestión

摘要: The Guarani aquifer system (GAS) extends beneath the territories of Argentina, Brazil, Paraguay and Uruguay thus represents a typical example transboundary aquifer. GAS is an important source drinking water for population living within its area. Because differences in legal norms concerning resources these four countries, urgently required framework shared management groundwater currently being drawn up. Within this context, conceptual regional hydrogeological model should be used as tool to delineate actions, particularly regions where flow transboundary. considered continuous made up Mesozoic continental clastic sedimentary rocks that occur Parana Chacoparanense basins, bounded at base by Permo-Eotriassic unconformity top lower-Cretaceous basaltic lava. shows trend from N S along main axis basins.
