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.

Database digitization for flood situation modelling of urban areas in the Divoká Orlice valley
Brych, Karel ; Dittrt, František ; Eliáš, Václav
For solution of various hydrological problems in a river basin particularly by means of some mathematical models in the environment ArcView a digital terrain model (DTM) is prerequisite. At present a state map atlas ZABAGED/1 in the form of digital topologic vector data in the 1:10.000 scale is getting available. This system contains land-surface elevation data in a vector format. Following the obtained information the state map atlas is to be completed for the whole state territory in the near future. The described procedure creates a substitute for digital terrain model (DTM) of the river Divoká Orlice valley in the reach affected by the flood in March 2000 with the view of mathematical modeling by means of the HEC-RAS, HEC-HMS, and WMS respectively. The accuracy of digitalization of the elevation model is lower than the elevation data of ZABAGED nevertheless the model allows preliminary analysis of the flood events with acceptable uncertainty.
