Abstract:: The hydrologic process was simulated by using the distributed hydrological model-SWAT in Lianjiang basin of northern Guangdong. Based on observed data of the daily runoff which were measured at Gaodao, Fenghuangshan and Huangjingtang gauging station from 2001 to 2005, the calibration and sensitivity analysis of the model were carried out. The calibrated model was validated for three gauging stations for a period of 5 years(2006—2010).The simulated monthly streamflow has Nash Sutcliffe efficiency value of 0.97, 0.89, 0.70 for the calibration period for the Gaodao, Fenghuangshan and Huangjingtang stations, respectively. The model can successfully simulate streamflow during validation period with the Nash Sutcliffe efficiency value of 0.90, 0.69, 0.69 and R² value of 0.94, 0.93, 0.92 for Gaodao, Fenghuangshan and Huangjingtang stations, respectively. The Result showed the SWAT model could be well used for runoff simulation in Lianjiang basin.
