The SWAT is a physically-based distributed hydrological model. Its runoff generation mechanism is more practical. The methods adopted in the process of runoff including surface runoff, interflow and groundwater flow are applicable to various conditions of climate and underlying surface. In this study, the SWAT (Version 2005) is applied to the Kuye River basin, one of typical watersheds with plentiful and coarse sand in the middle reaches of the Yellow River with arid and semi-arid climate. When the model in the Kuye River basin was developed, automatic calibration method within the SWAT Version 2005 was used to calibrate the model. According to the stream flow hydrograph at Wenjiachuan station, the mouth of the river, the parameters were further adjusted. Then, daily and monthly discharges from 1980 to 1985 have been simulated in the study area, and observed data series of three hydrological stations (Wenjiachuan, Xinmiao and Wangdaohengta) are used to evaluate the simulated discharge series of SWAT. The effects of physical mechanism for streamflow generation processes have been analyzed and discussed. The result shows that the relative error of water budget is about 10%-20%, while the Nash-Sutcliffe efficiency coefficient (Ens) is relatively low, with Ens of daily series being about 0.2 and monthly Ens around 0.6. Preliminary analysis of simulation results showed that the SWAT is not effective to simulate the discharge of interflow, baseflow and spring flood in the Kuye River basin. In addition, it is proposed that the SWAT runoff generation mechanism in arid and semi-arid regions need to be further investigated.
