USE OF FREQUENCY AND PROBABILISTIC ANALYSIS IN THE DETERMINATION OF MINIMUM REFERENCE FLOWS

Resumo

Considering the growing concern with the reduction of water availability worldwide, studies that aim at optimized projects and fair concessions for water use become important. With this perspective, this work presents a methodology for the determination of the minimum reference flow rates (Q_7,10, Q_90%, and Q_95%). The Itatiba hydrological station was chosen and its flow data were collected and statistically treated for subsequent application of frequency and probabilistic analysis. The results of both analyses led to close results. The methods employed in this work can be replicated in further research.
