Runoff Analysis in the Upper Tedori River Basin Considering Changes in Rainfall and Snowfall Under Global Warming

Key Points

• The research aims to analyze how global warming affects runoff characteristics in the upper Tedori River basin, particularly due to changes in rainfall and snowfall.
• Utilized d4PDF ensemble climate prediction data for climate analysis.
• Applied the Rainfall-Runoff-Incorporating snowmelt model for runoff analysis.
• Estimated snowmelt using the degree-hour method and temperature-dependent melt coefficients.
• Runoff analysis indicated increased river flow in January and February with a 4°C average global temperature rise.
• November and April showed a tendency to have no snowmelt runoff.
• April peak flow increased, but median flow decreased due to lack of continuous snowmelt.
