Abstract

In the process of production or processing of materials by various methods, there is a need for a large volume of water of the required quality. Today in many regions of the world, there is an acute problem of providing industry with water of a required quality. Its solution is an urgent and difficult task. The water quality of surface water bodies is formed by a combination of a large number of both natural and anthropogenic factors, and is often significantly heterogeneous not only in the water area, but also in depth. As a rule, the water supply of large industrial enterprises is located along the river network. Mergers are the most important nodes of river systems. Understanding the mechanism of transport of pollutants at the confluence of rivers is critical for assessing water quality. In recent years, thanks to the data of satellite images, the interest of researchers in the phenomenon of mixing the waters of merging rivers has increased. The nature of the merger is influenced by the formation of transverse circulation. Within the framework of this work, a study of vorticity, as well as the width of the mixing zone, depending on the distance from the confluence, the speeds of the merging rivers and the angle of confluence was carried out. Since the consumer properties of water are largely determined by its chemical and physical indicators, the intensity of mixing, determined largely by the nature of the secondary circulation, is of fundamental importance for assessing the distribution of hydrochemical indicators of water quality in the mixing zone. These characteristics are important not only for organizing water intake for drinking and technical purposes with the best consumer properties, but also for organizing an effective monitoring system for confluence zones.
