Abstract
Nowadays, the concern with protecting the environment and in particular with water resources is becoming more frequent. Thus contamination of soil and water table coming the processes of diffusion and convection of the concentration of pollutants that accumulate over time in sanitary landfills represents an extremely important factor. The present work uses the ideas of the Generalized integral transform technique (GITT) to provide a solution, explicit, for the distribution of the concentration in the propagation of contaminants in sanitary landfills. In the proposed mathematical modeling, it is considered a physical problem of mass transfer in transient, two-dimensional, porous medium with uniform profile of propagation velocity of the contaminant. The results presented in the form of graphs allow to evaluate the influence of the Peclet and the retardation factor on the concentration field.
