ResumoThis article presents the synthesis of studies performed to apply and analyze the performance of natural streamflow forecasting models of inflows into the Itaipu Hydroelectric Power Plant. For this purpose, two distinct lines of mathematical modeling were used: hydrological modeling and linear stochastic modeling. The composition approach is also evaluated, in which the final result of the forecasting model is obtained from a linear combination of the individual results supplied by the abovementioned methodologies. The streamflow forecasting models consider the availability of hydrometeorological information in the watershed analyzed, particularly of precipitation forecasts supplied by the ETA regional meteorological model, operated by the Centro de Previsao de Tempo e Estudos Climaticos do Instituto Nacional de Pesquisas Espaciais (CPTEC/INPE-Center of Weather Forecasts and Climatic Studies of the National Institute of Spatial Research). The good results obtained by using these models show their applicability to forecasting natural flows in the incremental basin of Itaipu
