Abstract
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/ Thomson & GelharY 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 ord
