Abstract

During the review of the effect of evaporation on the change of the hydrological regime of water reservoirs, an analysis was carried out on how global climate change will lead to a change in the water reservoir regime. Taking into account the sudden increase in air temperature and the effect of wind, the evaporation process in the month of June (June) was studied simultaneously during the years 2018 and 2022. During the research period, the effect of evaporation on the change of the hydrological regime of the water reservoir was determined by empirical formulas proposed by scientists such as B. D. Zaykov, A. Z. Braslavsky and P. A. Vikulina, and it was observed that the evaporation process is increasing year by year. According to accurate calculation books, the evaporation in June 2018 at the same time E0=86.14 mm, Ev=108.16 mm, in June 2022 this figure is E₀=121.27 mm, Ev=166.35 mm was found to be organizing. According to the analysis, we can see that the evaporation process in the reservoirs is increasing year by year, which causes a change in the hydrological regime of the reservoirs. The evaporation process is mainly caused by the increase in air temperature, the influence of the wind, and the fact that the surface of the reservoir is at its maximum level in May and June.
