O presente trabalho caracteriza os parâmetros de ondas e analisa o potencial hidrodinâmico para o transporte de sedimentos por tracao e de material particulado em suspensao, na costa adjacente a desembocadura sul do complexo estuarino de Paranagua em decorrencia do regime de ondas e das correntes de mares atuantes em periodos de mar calmo. A area estudada apresenta uma dinâmica complexa, devido a sua localizacao na saida de um grande estuario em uma costa com energia de onda relativamente elevada. Os objetivos principais foram os de caracterizar os parâmetros de ondas, avaliar o padrao de correntes junto a costa e estimar o potencial das correntes para o transporte de sedimentos. A caracterizacao dos parâmetros de ondas e das correntes paralelas a costa foi obtida atraves de correntometro/ondometro direcional eletromagnetico InterOcean S4, fundeado imediatamente atras da arrebentacao das ondas na praia do Balneario Atami. Os fundeios foram realizados em periodos de baixa energia de ondas, quando era possivel a sua instalacao, sendo que os resultados sao referentes a tais condicoes. Os resultados apontaram que a direcao preferencial de chegada de ondas e de SE, sendo que a direcao predominante de transporte medio longitudinal a costa foi de nordeste para sudoeste. As inversoes das correntes associadas as variacoes da mare indicaram uma efetiva influencia destas na direcao do transporte. Com base nos resultados obtidos, sao apresentadas sugestoes visando incentivar a implementacao de estrategias de monitoramento do fluxo de sedimentos costeiro. SHALLOW SHOALING ZONE DYNAMICS AND SEDIMENT TRANSPORT IN THE PARANAGUA BAY OUTLET Abstract This work presents a characterization of wave parameters and climate. It analyzes the hydrodynamic potential for sediments transport by traction as well by suspension (suspended particulate matter - SPM), carried out both by coastal currents, waves and the tidal circulation acting in the adjacent coast of the southern outlet of Paranagua Estuarine Complex. This area presents a complex dynamics, due to its location, morphology and the interaction of several coastal processes acting among its limits. The main goal was to characterize the wave parameters and climate, to identify the coastal currents, and to understand the roles of these currents for the sediments transport, quantifying its magnitude. The characterization of the wave parameters and of the coastal currents was obtained through mooring a directional wave and current gauge InterOcean S4 immediately seaward of the surf of Atami beach, PR. The moorings were accomplished in periods of low wave energy, the only ones allowing the deployment, and the results are regarding such conditions. The results suggested that the preferential direction of wave propagation is SE and the predominant direction of the mean transport, longitudinal to the coast, was from Northeast to Southwest. The inversion of the longitudinal currents was associated to the tidal changes and they indicated an effective influence of the tidal currents, acting in the southern outlet of the Paranagua estuary, in the direction of the mean mass transport. The hydrodynamic complexity of the place was directly related to these constraints, being linked to the net balance of the forcing of the tidal currents and the waves incidence. According to the obtained results, some suggestions were presented with the objective of suggesting strategies for the waves, currents and coastal transport studies, as a powerful tool for managing coastal zone problems.
