Bulgarian emergency response system for release of hazardous pollutants - brief description and some examples
The present paper demonstrates some results of the system for modelling of toxic air pollution due to possible accidents in industrial sites. The emergency response system is designed to help the relevant authorities in making important decisions, concerning the evacuation of the population in case of toxic air pollution due to accidents in industrial sites. The system is based on the following models: WRF, used as meteorological pre–processor; SMOKE - the emission pre–processor; CMAQ - the chemical transport model (CTM) of the system. The numerical results demonstrate the good performance of the models and the practical value of the preparedness and fast decision mode of the system.
