The objective of this paper is to develop a computational model for the prediction of the pollutant spread from a mass source over a complex terrain. The model comprises a two-dimensional, steady state flow model and a concentration model which employs the results of the computed flow field. The computational model is applied to predict the spread of pollutants for Sanbon city, and the two cases have been compard with the results of SF/sub 6/ trace experiments.
