PROCESSES THAT CONTROL THE FINE SEDIMENTS TRANSPORT IN THE RÍO DE LA PLATA ESTUARY
MEDIÇÃO, MODELAGEM, TÉCNICAS E TECNOLOGIAS NO CONTEXTO DA HIDROSSEDIMENTOLOGIA
The Rio de la Plata (RdP) is one of the most turbid estuaries in the world and one of the most important in terms of continental discharge and drainage area. The RdP has large social, ecological and economic importance for the countries along its shores and along the tributary rivers of its basin. Numerical models are excellent tools for conducting process studies and testing hypotheses based on observations. They constitute a "virtual laboratories" in which the forcings can be set "on" or "off", or even the environmental conditions can be modified. Observations of suspended fine sediments, particularly those remote and in situcollected on recent studieshave driven to the statement of several hypotheses about the processes that would control the concentration of suspended sediments in the different parts of the estuary. Nevertheless, the relative scarcity of data doesnot allow to demonstrate the validity of those hypotheses,the role of several physical processes and of the morphology remain unknown. The objective of this work is, therefore, to analyze the role of the different forcingsand the environmental conditions in the determination of the distribution of suspended fine sediments in the RdP applying processes oriented numerical simulations.
