The Sao Francisco River is a major river in Brazil, often cited as the third most important after the Amazon and Parana.

The Paraguay and Parana rivers flow through the southwestern region of Brazil, eventually forming part of the Rio de la Plata basin.

The mouth of the Amazon is characterized by a large estuary and islands, rather than a dense network of distributaries like a typical delta.

The Paraguay and Parana rivers are major tributaries that contribute to the Rio de la Plata basin, which flows through Argentina.
