Atmospheric Dispersion Modeling

Gaussian Plume (Concentrations vary with x, y and z) For a given x, the max conc. is at the plume centerline and decreases exponentially away from the centerline at a rate dependent upon the sigma values, y and z. y and z are functions of x Plume Centerline

Air Pollution Modeling – An Overview

The Gaussian plume model is illustrated in the figure below (Courtesy: Figure 19-5 of Boubel et al., 1994). The model was formulated by determining experimentally the horizontal and vertical spread of the plume, measured by the standard deviation …

FE Exam Review: Environmental

3 TIPS • Watch units! – Water: ppm = mg/L; ppb = μg/L; – Soil: ppm = mg/kg; – Air ppm IS NOT mg/L! • AIR conc in ppm-v = 100-1000x air in mg/L – Need molecular weight; molar volume – Pg. 19-20 of formula book has conversion factors • Frequently, you will use a MASS BALANCE approach • Review your CVEN 3414 homeworks/text; – Review CVEN 3424 if you had the course
