| Summary: | The Yellow River Basin (YRB) is the largest river basin in northern China,
which has suffering water scarcity and drought hazard for many years.
Therefore, assessments the potential impacts of climate change on the future
streamflow in this basin is very important for local policy and planning on
food security. In this study, based on the observations of 101 meteorological
stations in YRB, equidistant CDF matching (EDCDFm) statistical downscaling
approach was applied to eight climate models under two emissions scenarios
(RCP4.5 and RCP8.5) from phase five of the Coupled Model Intercomparison
Project (CMIP5). Variable infiltration capacity (VIC) model with
0.25° × 0.25° spatial resolution was developed based
on downscaled fields for simulating streamflow in the future period over YRB.
The results show that with the global warming trend, the annual streamflow
will reduced about 10 % during the period of 2021–2050, compared to the
base period of 1961–1990 in YRB. There should be suitable water resources
planning to meet the demands of growing populations and future climate
changing in this region. |
