Caracterização do Transporte Sedimentar Litorâneo junto à foz do Rio Itanhaém sob ação do Anticiclone Tropical Continental e dos Ciclones Extra-Tropicais

The study of the shore and beach environment is one of the most investigated issues in the last decades on the Brazilian coast. This kind of research involves scientists from several areas due to the large amount of variables interfering into this kind of environment. Meteorological studies, for instance are essential to the comprehension of beach evolution. The foreshore is the less known compartment among the existent beach compartment in such terms of complexity and difficulty that involves this kind of study. This work had as objective the monitoring of the foreshore under the influence of the Continental Tropical Anticyclone (ATC). The monitoring was made in the region of Itanhaém, central coast of São Paulo state. Near the outlet of Itanhaém River suspension material were collected and profiles of currentmetry and thermosalinometry were made. The meteorological specifications were obtained from properly literature. The observation of waves was done visually. The results showed that the ATC effects were punctual, causing the increase of the local rainfall without change of the incident wave trains characteristics. The plume of suspended material was inducted by the river discharge due to the rains, causing the increasing of the transport capacity from Itanhaém River.
