CASE STUDY: OIL SPILL USING MOHID SOFTWARE IN SÃO SEBASTIÃO – SÃO PAULO

Abstract

Among the main forms of pollution generated by oil, accidents involving spill in the marine environment stand out. There is a waterway terminal in the city of São Sebastião, so oil spills are a constant problem in this location. To evaluate the impacts caused by oil spills, this work simulates some hypothetical oil spills based on the terminal waterway of São Sebastião by using a two-dimensional hydrodynamic transport model and a Lagrangian approach using MOHID software. The hydrodynamic fields were validated by real tide data and the results show how the wind direction influences oil stain trajectory. It analyzes how the issue affects many nearby locations, especially considering touristic impact, since tourism is one of most important local economic activities of the region.
