Аннотация: Snow avalanches redistribute snow from the top of the mountain ridges down to the valley bottoms, which can be occupied by glaciers. The contribution of snow avalanches, coming outside the glacier limits, into the seasonal snow accumulation on a glacier is the least studied component of the glaciers’ mass balance. We present a new approach for the numerical estimation of snow avalanches contribution into accumulation on glaciers, allowing not to carry out detailed terrestrial snow surveys, based on DEM and meteorological data analysis using GIS and numerical modeling of snow avalanches. The approach was tested on the Batysh Sook Glacier located in the Kyrgyz Tien Shan. A case study was realized for the 2015/2016 balance year based on the high-resolution DEM obtained from a drone in July 2016 and the data of meteorological observations at the distance nearest to the glacier weather station. The snow avalanches accumulation on the Batysh Sook Glacier during the winter season 2015/2016 turned out to be 13±4% of the total accumulation. The results of numerical assessment of snow avalanches contribution into glacier accumulation possess a high scientific significance due to high sensitivity of all components of glacial mass balance to climate change. The developed approach is applicable in the long term not only for glaciers but avalanche’s contribution to river runoff that adds even more practical significance to the research.
