Abstract
This article deals with the research of glacial runoff.The general characteristic of glaciation of the northern slope of the Ile Alatau is given.The glacio-hydro-meteorological data of the glaciation zone, such as glacier morphometry, air temperature, precipitation, and river runoff, are collected and analyzed.The reconstruction of the annual runoff series of the studied rivers is carried out before the estimated period.The analysis of existing methods for calculating glacial runoff is performed.The glacial runoff of the Ile Alatau rivers is calculated for specific years of a long-term period by two methods: taking into account the runoff from individual morphological parts of the glacier and without dividing it into components (according to ablation formulas).For specific years 1955-2013, glacial runoff is calculated in six options for ten basins of the major rivers and along the slope as a whole, according to the formulas of different authors.The dynamics of glacial runoff is investigated.The trends of the further evolution of glaciation in this area are revealed.New dependences and formulas are proposed for calculating the temperature coefficients of snow and ice melting, as well as for determining the height of the firn line and the ablation value.
