Abstract
Studies on dispersion of pollutants in aquatic environments have been growing in recent research, due to increasing pollution and water scarcity in the world. Mathematical models are excellent technical tools that assist in the understanding of these phenomena. Thus, this work presents an analytical solution for the models of dispersion of pollutants in water bodies, the technique used to obtain the solution is the Generalized Integral Laplace Transform Technique (GILTT). The model used in the case study will be applied to simulate an experiment carried out on the Paraibuna River, state of Minas Gerais. The experiment aimed to evaluate the transport and dispersion capacity of the Paraibuna River, using fluorescent tracers. The results show the convergence of the concentration as well as the predicted concentration, by the GILTT method, in three points of collection of the experiment, for comparison the observed data and the Gaussian solution are plotted in the graphs. As expected, the results obtained show that the model is satisfactorily representing the observed data and has a behavior similar to the Gaussian solution.
