Rio de la Plata is the estuary formed by the confluence of the Uruguay (river in South America that flows from north to south and structures parts of the limits of Brazil, Argentina and Uruguay) and the Parana rivers (waterway in south Central South America, running through Brazil, Paraguay, and Argentina), empties into the Atlantic Ocean. Río de la Plata has numerous ports.
