High-resolution modeling of glacier meltwater contributions to lake water level fluctuations in the Baishui River Glacier No.1 basin.

ABSTRACT: Glacial lakes on the Tibetan Plateau are highly sensitive to cryosphere-hydrosphere interactions under climate change. This study applies a high-resolution framework to quantify sub-daily glacier meltwater contributions and hydrological impacts using Baishui River Glacier No. 1 and Blue Moon Lake Valley as a representative case. A gradient boosting machine model simulated hourly glacier melt from meteorological inputs, capturing episodic events and diurnal variability with high accuracy (RMSE = 0.0100 m/h against observed melt). Cross-correlation revealed an average 3.99-h lag between glacier melt and lake-level response, indicating delayed routing. Feature importance analysis identified air temperature and solar radiation as dominant melt drivers. Glacier meltwater contributed 87.62% of p
