Boundary conditions in random walk simulations of groundwater contaminant transport
The common approach to the modelling of solute transport by random walk particle method presumes that the particle that crosses domain boundary, cannot reenter the model. A series of authors e.g. Kinzelbach, 5 Thomson & Gelhar, 11 have noticed that the adsorbing boundary conditions cause an error in the solute transport models based upon a random walk particle method. The error can be significant in case the domain is not big enough, or in case the significant amount of solute moves close to the adsorbing boundary. In this paper the necessary volume of space enclosed by the model has been analysed, in order to obtain results within the acceptable, i.e. given accuracy, as well as supplement of the existing program based on random walk particle method, in order to reduce the effect of adsorbing boundary conditions.
