Modeling the movement of dangerous gases above the central part of Pardubice town
Dittrt, František ; Brych, Karel ; Jaňour, Zbyněk
The study was focused on the transport of the dangerous gases above the urban area of Pardubice town. The gaseous dispersion was caused after an accident with an outflow of chlorine in the chemical factory. Diffusion fields were simulated using a model of landscape surrounds the chemical plant at scale 1:3000. The results indicate fast decreasing of the surface concentrations due the intensive turbulent mixing inside the urban surface. Measurements were engaged in the tunnel by Infrared Analyzer IREX and results were presented as map layers in GIS.
