Effective tools to simulate and predict pollutant transport in water environments, especially rivers, are water quality models, which can contribute to saving the cost of labour and materials for a large number of chemical experiments to some degree. Due to special environmental pollution issues, water quality models have become very important in some cases. This paper identifies water pollution as a problem. Water quality models have become an important tool for recognizing the behaviours of pollutants in the water environment. In this research, there are general one-dimensional advection diffusion purposes to be resolved. The analytical solution of the model is found using the Laplace Transform method. These results are compared to those obtained by using a classical least square regularized method. For the graph of the solution, we interpret and discuss the concentration of the pollutant against time (t). � 2023 Author(s).
