MERINO-CASTRO, Glicina. Creation of a model of pollutans diffusion in soil-water system using a cellular automata. Rev. Mat [online]. 2011, vol.18, n.1, pp.63-76. ISSN 1409-2433.

In this paper is presented a developed model for a pollutant diffusion in a soil-water  system, for specific conditions in a real study area. A model that allows the  observations of the pollutant flow in the soil-water system and its behavior and  interaction with the different system elements, is searched with the purpose of  orientate and support the processes and techniques application for the pollutant soil  and water remediation. The basic model conditions are: 1) The pollutant is introduced  to the soil. 2) The pollutant flows from the soil to the water. 3) The introduced  pollutant concentration is variable during the process. 4) The pollutant may saturate  the soil. 5) The pollutant is adsorbed by the soil. 6) The model is developed in 2D, with  the possibility to be expanded to 3D. The model uses a cellular automata that contains  different zones with their own function rules. There are four considerate zones: i)  Introduction of the pollutant zone. ii) Soil zone (a porous media). iii) Soil-water  interaction zone. iv) Water zone.
