We present a model based on cellular automata for the simulation of reaction-diffusion processes that has been applied to the percolation of pesticides in the soil. The main contribution of our approach consists of a model where chemical reactions and the movement of fluid particles in a porous medium can be explicitly described and simulated. In this paper we show how the model has been used to reproduce the process that causes release of pesticides contained in the soil after their application to crops, into water flowing through the soil and to be carried to the groundwater layer, polluting it. A parallel version of the model has been successfully implemented on Cray T3E and SGI Origin 2000 parallel computers. © 2001 Elsevier Science B.V.

Abstract
We present a model based on cellular automata for the simulation of reaction-diffusion processes that has been applied to the percolation of pesticides in the soil. The main contribution of our approach consists of a model where chemical reactions and the movement of fluid particles in a porous medium can be explicitly described and simulated. In this paper we show how the model has been used to reproduce the process that causes release of pesticides contained in the soil after their application to crops, into water flowing through the soil and to be carried to the groundwater layer, polluting it. A parallel version of the model has been successfully implemented on Cray T3E and SGI Origin 2000 parallel computers. © 2001 Elsevier Science B.V.
