Landforms of Paraguay

The Guaraní Aquifer System is a large underground groundwater reservoir and hydrogeological system. It is a transboundary aquifer spread across four South American countries: Argentina, Brazil, Paraguay, and Uruguay.

The Pantanal is a natural region encompassing the world's largest tropical wetland. This gigantic seasonal floodplain lies mainly within Mato Grosso, and Mato Grosso do Sul in the Center-West Region of Brazil. However, small portions extend into northeastern Paraguay and southeastern Bolivia.

The Paraguay River is South America's fifth-largest river, running through Brazil, Paraguay, and Argentina. From the Brazilian state of Mato Grasso to its confluence with the Paraná River in Argentina, it serves as part of the Paraguayan border with Argentina and Brazil.

The Paraná River is the second-longest river in South America. Running through Brazil, Paraguay, and Argentina, it becomes an alluvial basin before emptying into the Río de la Plata. The Paraná Delta consists of several islands known as the Islas del Paraná.
