Monitoring of Water Level Variations of Bosten Lake based on Ice Cloud and Land Elevation satellite-1/2 Altimetry Data. Issue 1 (July 2021) - Ji, Miaomiao
Abstract: Bosten Lake is located in the arid area of China, it has experienced drastic change on water level due to the climate environment changes and human activities. Based on ICESat-1/2 satellite altimetry data, this paper extracted the water level data of Bosten Lake from 2003 to 2020, and analysed the multistage dynamics of water level. The result shows that: the overall water level of Bosten Lake appeared an upward trend from 2003 to 2020, and the annual rate of change was 0.06 m/a. From an annual perspective, the lake's water level gradually declined from 2003 to 2009, and then continued to rise until 2020. The lake water level fluctuates in a bimodal shape during the year, and March and October are the peak water level months. The research results can provide reference for the comprehensive management of water resources utilization in arid areas.
