HYDROCHEMISTRY OF THE TYRMA RIVER
Regional problems, 2021 The spatial-temporal dynamics of the dissolved substances content in the Tyrma River water and in its tributaries have been studied by the author. It was found great differences in the values of mineralization and concentrations of HCO3-, Ca2+, Mg2+ and Fe, due to natural conditions of the territory.
