Accurate time and site-specific forecasts of streamflow are important in effective reservoir management and scheduling. The present study aimed to compare the efficiency of Least Square Support Vector Machine (LS-SVM) as a new data driven model and a conceptual hydrologic model (Hymod) to simulate the daily streamflow in a representative watershed in US, Leaf River Watershed (1950 km2). For this purpose, 5-years period (1958-1962) of daily data including rainfall, potential evapotranspiration and streamflow were used. First 3-years were used as calibration (training) period in Hymod and LS-SVM and two remaining years were selected for validation (testing) periods in two models respectively. Performances criteria (Kling Gupta Efficiency (KGE), correlation coefficient (R2 ) and the Nash-Sutcliffe (NS) coefficient) for both LS-SVM and Hymod models in verification period were calculated and demonstrated that LS-SVM is a very potential candidate for the prediction of long-term discharges and then can be used as a promising method for hydrological prediction in un-gauged area.
