A random walk transport model was developed to avoid the amplitude and phase errors inherent in finite difference models. A three-point probability distribution was used for the random dispersive steps. The random errors associated with using a finite number of particles in the simulation can be controlled within normally acceptable limits by increasing with time the size of the region in which particles are counted to obtain concentration distributions. Model results have been compared with both laboratory and field tracer studies for steady flows.
