Abstract:Due to the shortcomings of traditional water level monitoring methods and the actual needs of monitoring water level change in Tai Lake, based on Envisat and Cryosat-2 altimeter data, Morlet wavelet analysis and Mann-Kendall test were used to analyze the changes in water level and its periodicity from June 2002 to December 2018. The altimeter-derived water levels were compared with in-situ data to estimate the accuracy. Afterwards, we analyzed the change trends of water level at different time scales and discussed the causes of the changes from aspects of climatic factors and anthropogenic influences. Results indicated that the water level derived from Envisat/RA2L2GDR data and Cryosat-2/SIRAL L2GDR data had high accuracies. The correlation coefficients between altimeter-derived water levels and in situ water levels were 0.559 and 0.845, respectively, at seasonal and annual scales. Therefore, altimeter data can be used monitor the change of water level in a long time series. From 2002 to 2018, the average water level of Tai Lake was 1.379m, the highest water level was 2.252m in June 2016, and the lowest water level was 0.832m in October 2011. Besides, the water level gradually increased from January to April every year, reached the peak around June, and then began to decline, and slightly increased again at the end of the year. Tai Lake had the highest water level in spring, the lowest in summer, with a difference of 0.041m. In the recent 20years, there were three kinds of periodic changes in the water level of Tai Lake:10~20months, 15~30months and 40~60months, in which the changes in the 40~60months scale were the strongest. Before April 2015, the water level had a significant downward trend, and experienced significant mutations in March 2003 and December 2004, respectively, while after that, water level had an upward trend. In the first decade of the 21st century, the water level of Tai Lake was mainly controlled by climatic factors. After that, the influence of human interventions gradually increased, causing the water level to show a different change pattern.
