RESUMO

Worldwide, the growing concern with environmental problems has happened quite rapidly, with special emphasis, in many cases, as regards sweet water resources; humanity has acted as if such resources were endless, and today the situation has changed into a very diferent reality. In this general picture, this work proposes the modelling of the evolutive behavior of pollutants on the water surface of rivers, focusing upon the Rio Balsas, in southern Maranhão State. A analysis of the chosen modelling process, led to the defnition computational algorithms, obtained in a MATLAB environment creating numerical tools for the simulation of accidents and processes, for theoretically testing prevention and protection strategies, as well as serving a general purpose of challenging choices and procedures that may lead to the presence of toxic material at levels which negatively affect local biota.
