Dispersion of conservative impurities in rivers: implications for compliance with environmental standards

The research goal is to understand the mechanisms of transport and transformation conservative impurities in river flows provide practical solutions ensure compliance with environmental standards. need close system equations make it suitable for solving problems caused addition motion empirical regularities. We use an approach based on fundamental hydrodynamics. main task mathematical transformations was: a) considering variability turbulent exchange coefficients along flow cross-section. b) obtained regularities linking characteristics coefficients. c) were performed obtain a group closed which approximate solution methods are known developed. best determining selected by applying model. For each desired variable, we equation evolutionary type, lends itself well algorithmization. schemes presented article allow us design computational algorithms using classical approaches impurity transfer variable exchange.
