Abstract:

In the context of climate changes melting of ice caps and glaciers occur on global scale. Mountain glaciers retreat creates environment for occurrence of glacial lakes and their expansion. In Tien Shan mountain range, there are hundreds of glacial lakes with the risk of glacial lake outburst flood, many of them already outbursted. Some ice dammed lakes like Merzbacher Lake located between South and North Inylchek Glaciers in central Tien Shan outburst periodically. This thesis is focused on landscape changes caused by GLOF of Merzbacher Lake, especially changes of the North Inylchek glacier, shape of the Inylchek Valley, and the whole Sary Jaz river basin. The research uses remote sensing data from the past 40 years in wide scale. The main data source are data collections especially from Landsat satellites from the past 40 years. The work contributes and provides some new facts and proves theories about consequences of GLOFs in landscape.
