Mathematical modelling in the river pollution

Abstract

Effective tools to simulate and predict pollutant transport in water environment especially river are water quality models, which can contribute to save the cost of labors and materials for a large number of chemical experiments to some degree. Due to special environmental pollution issues the water quality models become very important in some cases. Therefore, to identify water environment pollution, water quality model become an important tool to recognize the behaviours of pollutants in water environment. In this research, there are three main purposes to be resolved. The analytical solution of the model is found using Laplace transform method. For the graph of the solution, we interpret and discuss the concentration of the pollutant against time ( t ).
