Description
Summary:An impedance surface approach within a geographic information system (GIS) is used to model dispersion pathways for dense, gaseous, hazardous contaminants across complex terrain. The impedance surface methodology is tested using the Nogales Arizona-Sonora region of the US-Mexico border for simulation under varying wind conditions. This approach provides a realistic approximation of potential dispersion patterns in complex terrain where most existing dispersion models are inappropriate.
