摘要：

Paper presents numerical simulation of particles dispersion, lifting from a gypsum landfill under different weather conditions. Simulations consist of two parts: simulation of a long term impact of the particles on the surrounding area, performed by implementation of the Gauss dispersion model based computer code, and second, a CFD based simulation for assessing the flow and mass concentration fields in the vicinity of the landfill for several pre-selected flow cases. The GIS based topography is used for creating computational domain, and the ISC3 software for Gauss dispersion and the CFX5 software for CFD model are implemented. The results of both computational approaches are presented and compared. In the conclusions, a relation of the simulation results with existing environmental pollution levels is made.
