Between 2009 and 2020, 74 bathymetric surveys of 57 glacial lakes were conducted in the northern Tien Shan using ecosounding technique. The provided data on lake depths other parameters characterising three-dimensional geometry, bathymetrically derived volumes. sample included 21 glacier-connected lakes, 27 formed young moraines without with glacier tongue, eight older one rock-dammed lake. lakes’ volumes ranged between 0.029x10 5 53.89x10 m 3 largest value mean depth was 23 m. There is a...
The problem of shortage water resources, especially fresh and runoff during the growing season, is relevant for all countries in arid regions. In Central Asia, including Kazakhstan, mountainous regions are one main suppliers water. climate-caused degradation mountain glaciation causes changes ecosystems, having direct impact to human life, hydrological cycles, biogeochemistry rivers glacial lakes, affecting quality availability resources. article presents results seventy-year monitoring area...
The article considers the possibilities of assessing glaciation area the Northern Ile and Ile-Kungey glacier systems based on monitoring data from a limited sample test glaciers. During testing in each mentioned systems, two samples 10 glaciers, their total (20 glaciers) share glaciers named regions, corresponding system was calculated. According to results, values of correlation coefficient calculated actual (based results cataloguing) for three were 0.99, 0.98, 0.99 0.97,...
The article examines changes in glaciers on the territory of Aksu-Zhabagyly State Nature Reserve within Arys River basin (right tributary Syrdarya River). Spatial distribution and scale boundaries under conditions current climate change were assessed. average rate glaciation degradation for 2000-2023 is estimated. main factors trends contemporary are identified. air temperature during ablation period increased by 0.2-0.4 °C, amount precipitation March-May decreased 10-20 %. Directions...
The features of the impact snow avalanches to mountain forest landscapes Ile Alatau are considered. Regularities in distribution and forms avalanche activity have been studied. quantitative assessment on was carried out using remote sensing data GIS technologies. Based processed satellite images for determination landscapes, areas forests swath were calculated river basins high-altitude zones northern slope ridge. shares from total area defined. It has determined that significantly reduce forests.
Based on the data of MODIS spectroradiometer, area occupied by snow cover in upper reaches Syrdarya river basin was estimated. According to Kyrgyzhydromet for 1960-2021, variability air temperature and precipitation assessed. At Tien Shan meteorological station (Ak-Shyiryak mountains), average increased 1.9°С, at Uzgen – 1.1°С over 70 years observations. The amount precipitation, general, has changed insignificantly, an anomalous reduction during cold period not been noted. Comparison April...
