River pollution is a complex physical, biochemical and ecological process, which pose a global threat and challenge to environmental issues. The problem of reducing pollution and improving water quality can be solved by using the appropriate mathematical models and their implementation in software. Waste is considered a grave threat to our urban environments, especially our streams and rivers. From the study, it has been observed that improper practices of solid waste management carried out at the Lemina landfills site and the inappropriateness of leachate collection system and its treatment or recycling exert a tremendous impact on the surface and groundwater quality. This paper examines the main sources of pollution in the river and presents a mathematical modification of the river pollution. It addresses the problem of mathematical modelling of river pollution and pollutant dispersion in rivers. It summarizes the mathematical formulation in the field of river water quality modelling. Using mathematical modelling helps to predict the behaviour of self-purifying systems and to determine the results of actions of different processes on river systems.
