CHANGES OF THE AKHANGARAN RIVER MINERALIZATION UNDER ANTHROPOGENIC INFLUENCE

In the article the changes of the Akhangaran River water mineralization along the river length under anthropogenic influence based on long-term (1991-2020) data from 6 water quality observation points has been analyzed. Mineralization increased in the runoff consumption zone from 1.7 times (Angren point) to 6.9 times (Dustobod point (lower)) compared to the runoff formation zone (Yertosh point). The reason for the change in the mineralization of the river along its length is the discharge of industrial, municipal and agricultural wastewater.
