Runoff simulation in Jinghe River Basin based on the SWAT model

摘要

The distributed hydrological model of Jinghe River Basin was constructed through simulating using the distributed SWAT (Soil and Water Assessment Tool) model. The Jinghe watershed is delineated into 29 subbasins and 245 hydrologic response units. The model is calibrated with the measured monthly flow data from 1978 to 1989. In the process of calibration, six sensitive parameters including CN2, SOL_AWC, ESCO, etc. are determined. The results show that the SWAT model could effectively simulate the streamflow changes in Jinghe River Basin.
