CHANGES IN THE MASS BALANCE OF THE BARKRAK MIDDLE GLACIER, UNDER THE INFLUENCE OF CLIMATIC FACTORS AND ITS CONTRIBUTION TO THE FORMATION OF THE OIGING RIVER RUNOFF
Keywords:
glacier mass balance, climatic factors, river fed, runoff formation, hydrograph separation methodAbstract
In this paper annual mass balance of Barkrak Sredniy glacier for 2016-2020 was analyzed and influence of climatic factors on the glacier was studied. Moreover, the total glacial runoff from the Oygiang River basin was estimated based on the amount of runoff calculated by Barkrak Sredniy glacier. The estimation results were compared with the contribution of glaciers, determined by the method of hydrograph separation of water discharge of the Oygaing River. In conclusion, proposals and recommendations on studying glacier mass balance and their contribution to the river runoff formation were presented.
