GEOGRAPHY THROUGH MAPS

Río de la Plata estuary

The Río de la Plata is a broad estuary between Argentina and Uruguay. It receives the Paraná and Uruguay rivers and opens southeastward into the Atlantic.

Fast Facts

  • Buenos Aires lies on the Argentine shore and Montevideo on the Uruguayan shore.
  • Freshwater discharge mixes with marine water, creating salinity gradients and a sediment-rich plume.
  • The Paraguay contributes indirectly through the Paraná, rather than entering the estuary as a separate main mouth.
