Abstract

Abstract: In view of the safety problems of Sarez Lake and the difficulty in obtaining hydrological site data, resulting in lack of time-fixed and uniform precision of quasi-real-time lake water level information, this paper proposes a plateau lake water level retrieval method based on space-borne laser altimeter data (ICESat-1/2). Sarez Lake level time series survey is carried out by remote sensing altimetry technology and water level changes in the past 20 years (2003—2019) are reconstructed. Trend analysis and Mann Kendall (MK) nonparametric test are used to analyze the water level variation characteristics of the Sarez lake in the past 20 years. The recent trends and patterns of the water level in Sarez Lake are revealed. The results show that: ①The error of ICESat-1/2 laser altimetry radar data can be controlled within 0.05 m in the inversion of land lake water level. So the accuracy is highly credible, which provides favorited/promised data source for lake hydrological monitoring in no, lack data area. ②During 2003—2019, the water level of Sarez lake still shows a significant upward trend, and the rate of water level raise is about 0.15 m/a (p<0.01, two-tailed). ③The water level of Sarez Lake is highly volatile during the year (7~8 m at least). The highest water level occurs from September to October, the current average water level is about 3265 m; the annual minimum water level appears from March to May, and the current average water level is about 3259 m. The above findings provide data support and technical reference for the comprehensive management and safety assessment of Sarez Lake.
