Plata, Río de la

(rē`ō thā lä plä`tä), estuary, c.170 mi (270 km) long, SE South America, formed by the Paraná and Uruguay rivers. Between Argentina and Uruguay, the estuary is c.120 mi (190 km) wide at its mouth on the Atlantic Ocean and decreases to c.20 mi (30 km) near its head. Focal point of the second largest river system of the continent, the estuary receives a tremendous volume of water. Its northwestern end contains freshwater. Extensive sandbanks and shoals reduce the navigability, but constantly dredged channels permit navigation by large vessels; Buenos Aires and Montevideo are the chief ports. Discovered (1516) by Juan Díaz de Solís, it was explored by Ferdinand Magellan in 1520 and by Sebastian Cabot from 1526 to 1529. The first settlement on its banks was made (1536) at Buenos Aires by Pedro de Mendoza, the Spanish conquistador. A principal channel into the interior of SE South America, it is very important commercially. In English it is sometimes called River Plate. The viceroyalty of Río de la Plata, more or less corresponding to the present Argentina, Bolivia, Uruguay, and Paraguay, was established in 1776.

The Bonaerense Lower delta islands are formed by the accretion of silts transported and deposited by the Paraná river in the de la Plata river.
Unit B, downstream from A and locally referred to as forest nucleus, has a transitional hydrology between the fluvial influence of the Paraná river and the tidal influence of the de la Plata river.
Unit C forms the front of the delta and is subjected to direct influence of the tidal and eolic tides of the de la Plata river, which range from 1 to over 3 meters during strong southeastern winds.
The delta's accretion portion, where it grows by the deposition of sediments carried on the main rivers on their way to their mouth in the de la Plata river forming new islands and banks, constitutes Unit D.
The remaining species were mentioned as plant members of the Paraná river delta and the riverside of the de la Plata river by several authors (Hauman, 1923; Cabrera and Dawson, 1944; Cabrera, 1971, to name a few).
In addition, the tidal regime of the de la Plata river causes a bidirectional hydrological flow, which incorporates an additional hydric input and compensates for the seasonal drought characteristic of the Paraná river.
