Simulação do transporte de microplástico em zona costeira empregando a Plataforma MOHID: Estudos de caso no Estuário do Rio Macaé e na Baía de Guanabara

Abstract

A microplastic environment contaminate has received attention from researchers, and environmentalists. Currently, there are few models that simulate the trajectory of plastic debris. These models are used in order to predict the accesses and how they work according to the atmosphere. In this context, the objective of this work was to apply the hydrodynamic model, MOHID, with its Lagrangian module for a simulation of microplastics transport in the Macaé River Estuary and in the Guanabara Bay region. The platform used in the research has been elaborated in several processes that occur in estuaries, seas and oceans obtained, starting from field data for an adjustment of real models. It was concluded that the particle tracking module proved to be a significant tool for the study of the circulation of microplastics in the Macaé River and Guanabara Bay. The results extend to a lower level, since in both proportions they were more plastic, with the advance towards the sea, justifying the reason for the elevated Guanabara Bay. Finally, other simulations are published taking into account other factors, such as meteorological forces in the study region.
