Mondo Knows Facts
Two rivers merge into one vast estuary
The Paraná and Uruguay meet to form the Río de la Plata between Argentina and Uruguay The estuary is about 290 kilometres wide where it meets the Atlantic and carries muddy water far out to sea. Buenos Aires stands on the southern shore and Montevideo on the northern one. Silt from the Paraná keeps the shipping channels shallow, so dredging is continuous. It sits in Mondo's world geography collection, one of 200 facts that each trace back to the reference below.
