Basin Model of Total Dissolved Salts Transformation in Water of a Small River (the Kirgizka River, Tomsk, Russia)

Abstract

The basin model of total dissolved salt transformation in river water has been developed. It was tested in the Kirgizka River, the right tributary of the Tom River (Russia, Western Siberia, Tomsk). It was shown that the river system has the capacity of selfpurification and is characterized by rather stable salt composition. It is explained by the fact that the growth in dissolved salt concentration in river water is limited to some extent by, firstly, dilution of more mineralized groundwaters drained by rivers, and, secondly, relatively low solubility of some compounds
