Long-term dynamics and trend of ion sink of Amur river
 In the winter low-water period near Khabarovsk, Russia

Abstract

The long-term dynamics and trend of the ion sink of the Amur River near Khabarovsk, Russia, in the winter low-water period were studied. The hydrological and hydrochemical characteristics of the main tributaries are given. The spatial heterogeneity of the distribution of mineralization along the length and width of the Amur is noted. The influence of large floods on the winter runoff of solutes has been established. The long-term increasing trend of ion sink in the winter low-water period due to hydropower construction is shown.
