Behaviour of Pollutants in the Upper Reaches of East Jiu River Case Study

Abstract

Surface water pollution is one of the consequences of modern society development through permanent pressures on the environment imposed by economic activities to provide the necessary resources for keeping modern living standards. Degradation of fresh water bodies is caused by the disappearance of natural water collection areas, deforestation and unsustainable farming practices, river pollution with wastes and the discharge of non-treated domestic and industrial wastewater into natural recipients. The main purpose of the mathematical modeling of rivers is to predict pollution dispersal in longitudinal and transversal directions, taking into account water body mixing coefficient. This paper is devoted to monitoring of physico-chemical indicators in the sampled river reaches and simulation of pollutant dispersal in the upper reaches of the East Jiu river.
