Projection of China’s future runoff based on the CMIP6 mid-high warming scenarios

This study uses the EDCFM method to downscale and bias-correct six CMIP6 GCMs for China's hydrological applications. The results indicate that SSP2-4.5 and SSP5-8.5 scenarios will bring increased volatility in precipitation, evapotranspiration, and runoff. Multi-year average annual values are projected to increase under these scenarios.
