Abstract: A mathematical model has been developed specifically for accurately quantifying the dispersion of emissions in the near vicinity of a groundlevel area source. This model accounts for variations with height in the wind speed and eddy diffusivities, includes dry deposition as a contaminant removal mechanism, and contains a quantitative representation of the roughness of the downwind terrain. An evaluation is made of the sensitivity of the results to the various input parameters. The results obtained using this model are compared with those using simpler plume models.
