For this work, we developed a methodology based on computational fluid mechanics to study the behavior of pollutant transport in natural rivers, subject to different types of releases. The methodology uses fundamentals of mass transfer theory, evaluating the concentration of pollutants fields over time and space in order to verify the influence of parameters such as the channel bottom slope and roughness coefficient in the behavior of this field. To this end, we developed a computer program that allowed for a set of simulations for various types of real scenarios found in the relationship between man and river. The results showed that the behavior of concentration is greatly influenced by the hydraulic characteristics of the channel, the hi...
