- Abstract:
-
Anjiagou Watershed of the Loess Plateau was taken as the study area. By using GIS and RS technology, the meteorological data, DEM data, land use data of Anjiagou Watershed were established to construct the hydrological model of Anjiagou Watershed based on SWAT model. Data series from 1982 to 1999 were used to calibrate the SWAT model and period from 2000 to 2010 was employed to validate model. The values of Nash-Sutcliffe coefficient and the measured and simulation correlation in calibration period and the validation period were 0.71, 0.69 and 0.73, 0.68, respectively, meeting the requirements of model simulation. The results show that SWAT model can basically reflect monthly runoff hydrologic process in Anjiagou Watershed and has a certain practicality in terms of providing the basis for efficient allocation of water resources in Anjiagou Watershed.
