The dynamics of rivers in the Amazon is predominantly linked to threats or natural events that may or may not trigger environmental damage. In March 2013 a large portion of soil slid into the interior of the Santana channel in Amapá, this abrupt mass movement took with it the Port of Santana and its respective facilities. The forensics findings identified a sensitive soil that had not previously been identified in Brazil. Due to the unusual behavior of the material on the shores of the Port of Santana, the new soil characteristics identified and because it is a port area, which houses several materials of great polluting potential, including bulk terminals, pipelines, the need arises to evaluate the behavior of a possible oil spill through hydrodynamic modeling. The software SisBaHiA® - Base System of Environmental Hydrodynamics was chosen to be used in the development of the models because it has a friendly interface and is already widespread in related lines of research. With the models and simulated scenarios, we identified the proportions of a new landslide accident involving these fuel reserves, the areas of the Santana channel that would be directly affected by the oil and what is the response time that the responsible institutions would have to trigger actions for mediation and containment of an accident of this proportion. Thus, the study seeks to obtain timely management mechanisms and decision-making about a possible accident.
