【 摘 要 】

In this paper, the rainfall-runoff process was simulated by three hydrological models of SMAR, Sacramento and Tank based on Bass river catchment in the State of Victoria, Australia. The results of the three models are compared by Nash-Sutcliffe coefficient and RE (relative error coefficient of total runoff), which showed that the Nash-Sutcliffe coefficients of the three models are all above 80%, however, considering the RE, only the Sacramento model is kept within 10%, which meets the requirements during the both calibration and verification periods. Therefore, it can be found that the Sacramento model is the most ideal hydrological model for the chosen catchment. The results can be used in hydrological forecasting, soil and water management, environmental planning and etc.
