The dispersion in the atmosphere, of light gases emitted from elevated vertical sources, ie. stacks, was studied. As a result, a user-friendly graphical software employing a microscale Gaussian model based on the I.S.C. (Industrial Source Complex Model), which is approved by the E.P.A. (Environmental Protection Agency, U.S.A), was produced.

For the dispersion of heavy gases in the atmosphere, the software developed was based on the SLAB model. SLAB is approved by E.P.A. (Environmental Protection Agency, U.S.A), and treats denser-than-air releases, including ground level and elevated jets, liquid pool evaporation, and instantaneous volume sources. The developed software runs in real time in a graphical user-friendly environment.

The case of AMYNDAION MINES
The particular work addressed the problem of atmospheric dispersion of particulate matter (PM) from the overburden dumps of a mine, using a commercial CFD software, includingmost of the complex physical phenomena in atmospheric diffusion. In the vicinity of the city of Amyndaion there is a large mine that provides lignite for the thermal power stations of the Hellenic Public Power Corporation. The excavated land is dumped in nearby open pits, which are planned to be extended Southern. These pits are sources of air-suspended particulate matter that can affect the nearby residential areas.

The work is a clear example of the successful use of a complex numerical model in an environmental study.
