- Abstract
The aim of this study was to evaluate the performance of conceptual models Sacramento - Soil Moisture Accounting (SAC-SMA) and IPH II for daily flow estimation in Piracicaba river basin, Minas Gerais, so that they may be used in the planning and management of water resources in the river basin. The study was carried out in three runoff-monitoring sections on Piracicaba river basin, located in the State of Minas Gerais - Brazil. Model calibration was performed through the Shuffled Complex Evolution (SCE-UA) algorithm, whose objective function was the Nash-Sutcliffe efficiency index. The Nash-Sutcliffe efficiency index values obtained in the three monitoring-sections were 0.87, 0.78, and 0.71 for the SAC-SMA model, and 0.88, 0.80, and 0.73 for the IPH II one. These values confirm that the models are "appropriate and good" for daily flow estimations. Overall, both models can be further used for hydrologic simulations and water resources management in tropical river basins.
