摘   要:

A generalized simple model was presented to describe the dispersion of a pollutant in downwinddistances in stable atmosphericboundary layer (ABL). Advection-Diffusion Equation was solved for a nearlyconstant emission rate of pollutant from a point source with assumption of well –defined edge plume.Theproposed model investigates dispersion and advection of conservative material as it travels downwind.Determination and an explicit approximate expression for the Ground Level Concentration (GLC) were provided.Results were evaluated with the observations obtained from diffusion experiments in moderate and lowwind.The present model shows good performance with the observed data and can be used to investigate theshort-range dispersion of pollutant. It can be concluded thatthe good parameterizations of input data such aswindspeed and plume heightleads to well perfection in the agreement betweencomputed and observedconcentrations.
