Acesso em:.https://repositorio.ufpa.br/handle/2011/11503The estuarine environments are widely studied over the past decades due to its social, environmental and economic importance. For example, the strategies to contain oil spill are based on hydrodynamic modeling research. The application of numerical models to predict and analyze circulation patterns inside coastal water bodies is growing in the country. In northern Brazil the use of those models is still experimental. In this work was used the software SisBaHia to implement, calibrate and validate a hydrodynamic model to the water body “furo da Laura” (FL), located on Guajara-Mirin river, on the coastal region of northeastern Pará. The model was calibrated with previous data about surface elevation and current speed collected in three periods: dry season of 2013, rainy season of 2014 and dry season of 2014. The flood and ebb tide flow occurs simultaneously in two entrances that the FL presents. The goal was to locate the barotropic convergence and its seasonal variation. It was simulated one month during the rainy season (February) and one month during the dry season (August). It was simulated a lagrangian transport with particles released in Sol bay with an analysis of its horizontal dispersion. The convergence sites were found nearby the south entrance of the FL and the divergence sites have a spatial variation due the tide cycle. The particles released in the Sol bay tend to leave the modeling domain and don’t penetrate the FL, but they contribute with the erosion and sedimentation process that occurs in coast of the Colares Island.Acesso AbertoHidrodinâmicaSisBaHiaModelagem hidrodinâmicaConvergencia barotrópicaHydrodynamic modelingBarotropic convergenceFuro da LauraModelagem hidrodinâmica 2DH no furo de Laura - Nordeste ParaenseDissertaçãoCNPQ::CIENCIAS EXATAS E DA TERRAHIDRODINÂMICA DE ESTUÁRIOSGEOFÍSICA MARINHA
