CURRENT STATUS OF GLACIATION OF THE DRUMDARA RIVER BASIN (GUNT RIVER BASIN)
State Scientific Institution “Center for the Study of Glaciers of the National Academy of Sciences of Tajikistan”
The article presents the results of studies of the state and quantity of glaciers in the Drumdara river basin, the right tributary of the Gunt river basin, for the period 1977-2020, implemented using satellite images from Landsat – 2, 7 and Sentinel – 2A satellites.
The data obtained from the analysis and evaluation of the research results made it possible to clarify the number of glaciers in the studied basin of the Drumdara River. Due to the fact that one glacier is located behind the ridge that bounds this basin, and two glaciers were degraded, we excluded them from the list of glaciers in this basin. Thus, it has been established that in 2020 there are 25 glaciers in the Drumdara river basin, which is 10.7% less (3 glaciers) less than in 1977. And as a result, the area of glaciation of the upper reaches of the Drumdara river for the period from 1977 to 2020 decreased by 1.28 km2 or 10.9%.
