  • Liu, Jifeng and Y. Ding, Research on simulation of hydrological process in Buha River Catchment of Qinghai Lake. In preparation.

Climate changes have an significant impact on water resource of West China, it was proved by the rapid shrinking of Qinghai Lake. SWAT model were used in the catchment of Buha River. Spatial heterogeneity of geographic elements such as climate, topography, soil and land use were considered in the model. Streamflow of Buha River in past decade years were modeled with SWAT model. Sensitivity tests indicate that climate change is the main reason of streamflow decreasing from 1980s to 1990s. With the climate scenarios and trend in the future, steamflow of Buha River were forecasted that there are some uncertain in streamflow changes in the future. It is more possible that streamflow is increasing in the future basing on the characteristic of climate changes in the future. In order to make more authentic prediction, statistics downscaling methods are used in this paper to obtain the climate scenarios by GCM output from NCAR PCM1.
