Estudo da análise de risco em rios sujeitos a lançamentos de efluentes em função da vazão do rio e da carga lançada

Abstract

This work developed a formulation based on fuzzy theory, together with pollutant transport models, to study the fuzzy contamination risk as a function of river flow and effluent concentrations. The study uses parameters defined in the law to establish the class of the river and thus calculate, for each type of launch, the risk of contamination and the assimilation capacity of the river. For the accomplishment of the simulations a computational program was developed, in FORTRAN language that gave support in obtaining the results for the most diverse scenarios proposed. The results showed that the fuzzy theory can become a safe alternative to the control of pollution of rivers in general, thus providing a basis for the management of water resources.
