According to the scientific researches of many scientists in the world, it is causes changes of the whole complex hydrometeorological factors. The main factor that determines the thermal regime of the rivers is air temperature. In this paper the long-term tendencies of the average annual water temperature and air temperature in the Siverskyi Donets River Basin (within Ukraine) was researched. The period of observation on gauging stations is the start of observations till 2013 inclusive. The synchronicity and synchronicity phase their fluctuations was analysed. The estimation of homogeneity of the hydrometeorological data based on the hydro-genetic analysis (the mass curves, the difference integral curves, the combined chronological graphs) have been carried out, because this river basin has great anthropogenic load.enaverage annual water temperature, average annual air temperature, homogeneity, asynchronicity phase, hydro-genetic analysis.Article
