The Rio de la Plata is a large and shallow water body that discharges onto the Atlantic Ocean. The main driving forces for the river flow are the bathymetry, tides, the outflow from the Parana and Uruguay rivers and the winds. A numerical model covering the entire river was set up with the objective of increasing our understanding of the hydrographical. features and morphological dynamics in the Estuary. The simulations revealed a counter-clockwise residual circulation in the Samborombon Bay and an eastward net flow near the Uruguayan coast. The residual flow is forced by both the tides and the bathymetry. The residence time for the entire river ranges from 40 to 80 days. However, residence times above 120 days was found in the Samborombon Bay. Three corridors of flow have been identified. (c) 2005 Elsevier Inc. All rights reserved.
