Formation of the chemical composition of water in the upper reaches of the transboundary Tisza River (Ukrainian Carpathians)

Abstract

The transboundary river Tisza, whose headwaters are located in the Transcarpathian region of Ukraine, is the largest left tributary of the Danube and plays an important ecological role in its basin. Apart from Ukraine, the Tisza River basin is located in Romania, Hungary, Slovakia and Serbia.The significance of studying the formation of the chemical composition and quality of water in the upper reaches of the Tisza River is that it gives an idea of the chemical composition and quality of water in the river, which then flows through the territory of neighboring countries. The chemical composition of the water in the upper reaches of the Tisza River is formed under the influence of high humidity (average annual precipitation is about 1200 mm) and the spread of salt-poor flysch rocks.
