Resumo: The Guarani aquifer system (GAS) extends beneath the territories of Argentina, Brazil, Paraguay and Uruguay and thus represents a typical example of a transboundary aquifer. The GAS is an important source of drinking water for the population living within its area. Because of differences in the legal norms concerning water resources in these four countries, an urgently required legal framework for the shared management of the groundwater is currently being drawn up. Within this context, the conceptual regional hydrogeological model should be used as an important tool to delineate shared actions, particularly in regions where the groundwater flow is transboundary. The GAS is considered to be a continuous aquifer made up of Mesozoic continental clastic sedimentary rocks that occur in the Parana and Chacoparanense sedimentary basins, and is bounded at its base by a Permo-Eotriassic regional unconformity and at the top by lower-Cretaceous basaltic lava. The groundwater flow shows a regional trend from N to S along the main axis of these basins. With regard to the major tectonic structures of these sedimentary basins, various main hydrodynamic domains can be distinguished, such as the Ponta Grossa arch and the Asuncion-Rio Grande dorsal. Regional recharge areas are primarily located in the eastern and northern outcrop areas, whilst the western end of the GAS, the Mato Grosso do Sul, contains zones of local recharge and regional discharge. Transboundary flow is observed in areas confined to the national borders of the four countries. Nevertheless, due to the groundwater residence times in the GAS special management actions are called for to prevent over-exploitation, particularly in the confined zones of the aquifer.
