| Abstract |
Glaciers holds an important place in maintaining the ecological balance, moreover it is the major source of fresh water. Snow and ice cover are extremely important in the Himalayan region. It not only... monitors the region's climatic conditions, but it also controls the local people's day-to-day livelihood structure. Snow and glaciers are two of the most important land covers on the earth’s surface. As a result, it is critical to examine, monitor, and map these land covers on a regular basis. Thus, in the present study an effort has been made to study the Wakhan corridor glaciers in Afghanistan from 1994-2019. Landsat satellite images were used to monitor the glacier change as well as to delineate the glaciers lake. Various GIS techniques are used to complete the research like band rationing, on screen digitization, statistical analysis. During the study, it was clearly identified that the snow line as the accumulation zone in this part is receding, with the melting of glaciers there has been increase in the numbers of glacial lakes is a warn of a danger in the coming days. In this study, glacier inventory were calculated followed by estimation of accumulation area ratio (AAR) of each glacier. Thus, multi-temporal Landsat images were used to estimate change in glacial area and accumulation area ratio (AAR) respectively. The estimated AAR was used to assess the glacial retreat. A total of 64 lakes were identified using this and the areas of each of these lakes were calculated in ArcGIS desktop software. Majority of these lakes are lateral moraine glacial lake.show more
