Resumo: |
This research proposes a methodology to study the behavior of the Biochemical Oxygen Demand and of the Dissolved Oxygen Concentrations, in a river, subject to effluent discharges. The study is based on the transformation of the Streeter-Phelps Mathematical Model to a Streeter-Phelps Fuzzy Model, where the concentrations of BDO and of DO are calculated as membership functions. In such way, it is possible to incorporate uncertainties in the model, so that it allows developing a methodology for the determination risk and the reliability of a body of water do not assist the use conditions established by norm, when it receives a load pollutant, originating from a concession of grants of effluent discharges. The research uses a computational program, developed for this research, to make calculations, starting from the model equations, the BOD and the DO concentrations, in the membership functions. It was also developed a subroutine that allows that the risk and the reliability could be calculated for the river, subject that receives effluents discharges. The results showed that this fuzzy methodology is an alternative to be considered in the questions related with Integrated Water Resources Management. |
