Title: Runoff Simulation of Luanhe River Basin Based on SWAT Model
Abstract: The SWAT model was used in the Luanhe river basin to carry on the natural runoff simulation.The model parameters were calibrated and the model was validated using the reverted flow data from the three hydrologic stations of Chengde,Sandaohezi and Luanxian.The results show that during the calibration and validation period of the Luanxian hydrologic station,the coefficient of determination and Nash-Suttcliffe efficiency coefficient of simulated and observed values is greater than 0.90;the relative error is about 5.00%.The verification of model shows higher accuracy,and the model is applicable in the study area.Compared with 1985,the changes of land-use are the decrease in forest area and the increase in the area of arable land,grassland in 2000,which leads to runoff increased by 2.91%,while the increase in precipitation during the year had strengthened the influence of the underlying surface change on runoff.
