Abstract
t. The aim of the work is to study the chemical composition of snow cover and meltwater from the Garmo glacier and their contribution to the formation of the hydrochemistry of the Obikhingou river. The results of monitoring the meteorological conditions of the Obikhingou river basin and hydrology for the period 1960-2020 are presented. According to the estimates, the rate of increase in the average annual temperature values for the period 1960-2020 in the Vakhsh river basin as a whole flows differently and is in the basins of its tributaries: Surkhob 6.3∙10-3 оC/yr, Kyzylsu 13.5∙10-3 oC/yr and Obikhingou 18.6∙10-3 oC/yr. The temperature increases on the Vakhsh River upstream by 2050 is expected 0.4-0.7 o C compared to the period 1960-2020. For the period 1960-2020 there was a slight increase amount of atmospheric precipitation in the Obikhingou river basin with an average annual value of 3.7 mm/yr. By determining the concentration of chemical elements on the Obikhingou river downstream, the values of indicators (SAR, %Na+, SSP and ESP) of the applicability of river water for irrigation were calculated that were significantly lower than their critical values.
