VARIABILITY OF WATER EXCHANGE BETWEEN THE WESTERN AND EASTERN PARTS OF THE BALKHASH LAKE

This article examines the variability of water flow velocity and volume in the Uzynaral Strait, which divides the Balkhash Lake into the western and eastern parts, based on hydrometric field observations conducted in 2024. The study involved measurements of water movement in the strait, allowing the identification of spatial and temporal patterns in hydrodynamic processes. These measurements included flow direction, velocity, and the cross-sectional profile of the channel. Special attention was given to meteorological factors influencing flow dynamics, such as atmospheric pressure, wind, and air temperature. The analysis of the collected data revealed that the direction and intensity of the water flow are closely linked to these climatic conditions. The findings can be applied to hydrodynamic modeling of the Balkhash Lake, forecasting changes in water level regimes and water balance, and informing strategies for river runoff management in the lake’s catchment area.
