Resumo: The present study consists in simulate oil spill events in port region of Rio Grande city, Rio Grande do Sul, Brazil, using numerical modeling. In order to accomplish that was carried out a hydrodynamic simulation during 365 days, being this equivalent to daily means calculated between 2003 and 2015. The oil spill simulations were used to identify the mainly forcing which control the oil displacement, as the final destination. The results showed that the oil displacement tendency occurs due to the combination of wind effects and freshwater discharge of Patos Lagoon. During Summer and Spring periods, the Northeast winds occurred with higher frequency, being this the mainly forcing for the oil displacement. In this period, the discharge presented values below 2500 m³/s, making the action of currents less significant. In the coldest months, the high discharge was combined with the effects of currents controlling the oil displacement, became the wind effects less significant. Regarding the susceptibility of the oil arrival in analyzed sectors, it is possible to emphasize that Super Porto (super port) was the most affected in all seasons, followed by Salt Marshes, which was detached as the most worrying, since it presented high oil concentrations and it has the highest Littoral Sensitivity Index. Finally, information about possible leaks in the Patos Lagoon estuary, contribute to contingency plans, and enable a quick response to contamination in this environment.

Para isso, foi realizada uma simulação hidrodinâmica de 365 dias, sendo esta equivalente às médias diárias calculadas entre 2003 e 2015. Ademais, simulações de vazamento de óleo foram utilizadas para identificar as principais forçantes que controlam o deslocamento da mancha, assim como, seu destino final. Os resultados mostraram que a tendência do deslocamento do óleo ocorre devido à combinação dos efeitos do vento e da descarga dos afluentes da Lagoa dos Patos. Durante os períodos de verão e primavera, os ventos de Nordeste resultaram mais frequentes, sendo estes os principais responsáveis pelo deslocamento das manchas de óleo. Além disso, a descarga dos afluentes apresentou valores abaixo de 2500 m³/s, tornando a ação das correntes menos significativas. Nos meses mais frios, a alta descarga dos afluentes foi combinada ao efeito direto das correntes para deslocamento do óleo, tornando o efeito do vento menos significativo. Em relação à suscetibilidade à chegada do óleo, é possível ressaltar que o Super Porto foi o mais afetado em todas as estações do ano, seguido de Marismas, que foi destacado como o mais preocupante, uma vez que apresentou grandes concentrações de óleo e possui o maior Índice de Sensibilidade do Litoral. Por fim, as informações disponibilizadas sobre possíveis vazamentos no estuário da Lagoa dos Patos, contribuem com planos de contingência, e possibilitam uma resposta rápida à contaminação neste ambiente.Programa de Pós-Graduação em Integridade de Materiais da Engenharia2021-09-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.unb.br/index.php/ripe/article/view/35042Revista Interdisciplinar de Pesquisa em Engenharia; Vol. 7 No. 01 (2021): Revista Interdisciplinar de Pesquisa em Engenharia ; 18-28Revista Interdisciplinar de Pesquisa em Engenharia; v. 7 n. 01 (2021): Revista Interdisciplinar de Pesquisa em Engenharia ; 18-282447-610210.26512/ripe.v7i01reponame:Revista Interdisciplinar de Pesquisa em Engenhariainstname:Universidade de Brasília (UnB)instacron:UNBporhttps://periodicos.unb.br/index.php/ripe/article/view/35042/30970Copyright (c) 2021 Revista Interdisciplinar de Pesquisa em Engenhariahttps://creativecommons.org/licenses/by-nd/4.0info:eu-repo/semantics/openAccessLopes, BrunoTrombetta, Thaísa Moller Jr., OsmarMarques, Wiliam2021-09-17T20:20:47Zoai:ojs.pkp.sfu.ca:article/35042Revistahttps://periodicos.unb.br/index.php/ripePUBhttps://periodicos.unb.br/index.php/ripe/oaianflor@unb.br2447-61022447-6102opendoar:2021-09-17T20:20:47Revista Interdisciplinar de Pesquisa em Engenharia - Universidade de Brasília (UnB)false
