Evaluation of a method for estimating pollution concentrations downwind of influencing buildings

Atmospheric Environment 18(11): 2313-2338

Evaluation of a method for estimating pollution concentrations downwind of influencing buildings

A simple method for estimating enhanced dispersion resulting from the overall effect of buildings was presented and evaluated. A framework for applying the method to general plume dispersion modeling problems was suggested and examples were provided. The Gaussian plume equation was modified to incorporate building wake enhanced dispersion parameters beyond the wake cavity region, and the resulting ground-level plume centerline concentration estimates were compared to 10 sets of field measurements. The method provided a good correction for the overall effect of adjacent buildings. The effect of building wake enhanced dispersion on maximum ground-level concentrations was to decrease their values for releases near ground-level and to significantly increase their values for elevated releases. For elevated releases, enhanced horizontal dispersion diluted the plume more rapidly; enhanced vertical dispersion also rapidly diluted the plume but it also brought the plume to ground-level while the in-plume concentrations were still high.
