This paper briefly introduces to Australia Water Balance Model (AWBM) and its application for the midstream of the Yellow River. The results show that AWBM has good simulation results for monthly discharge, Nash-Sutcliffe efficiency in both calibration period and validation periods is above 60%; while having poor simulation ability for daily discharge. Although the model has only 6 parameters, they can compensate each other to some extent. Finally, the causes that result in limitation of the model application are analyzed and discussed.
