Border disputes

With Bolivia

With Uruguay

  • A triangular region, named Rincão de Artigas in Portuguese, is controlled by Brazil and claimed by Uruguay. The dispute is due to a disagreement as to where a stream known as Arroyo de la Invernada begins and where it ends.
  • Brazilian Island, a river island at the junction of the Quaraí River and the Uruguay River on the border between Argentina, Brazil, and Uruguay is claimed by both Uruguay and Brazil. Brazil has de facto control of it.

Water falls

With many of Brazil's borders defined by rivers, there are several water falls along the border. The most notable border water falls include the Iguazu Falls on the border with Argentina and Orinduik Falls on the border with Guyana.

Until 1982, the border with Paraguay contained the Guaíra Falls. The falls were submerged following the construction of the Itaipu Dam.[2]
