Abstract
Plume descriptors, constituting the first four moments of the concentration distribution, have been obtained for a Gaussian deposition plume model. Analytical expressions for the plume descriptors (centroid, variance, skewness and kurtosis) for point source ground-level and elevated releases are derived from a solution to the advection-diffusion equation accounting for deposition at the ground surface. A sensitivity analysis has been carried out to investigate the effect of deposition velocity and source height on the plume descriptors. For the particular case of a fully reflected Gaussian plume from a ground-level source, the centroid and the standard deviation have been found to vary as square root of downwind distance whereas skewness and kurtosis are independent of downwind distance, the approximate values being 0.995 for skewness and 3.87 for kurtosis.
