Integration of Environmental Models Based on Fluid Mechanics in GIS
Popis výsledku v původním jazyce
An exploration of dust dispersion over the surface of coal mines requires more complex modelling tools in order to estimate dust emission and dust transport. Thus, spatial data and data originating from a numerical simulation are integrated into a GIS environment. The Reynolds averaged Navier-Stokes equations for incompressible flows with turbulent algebraic extensions are used for dispersion modelling of the wind flows and dust transport. In addition to spatial data management, the GIS is used for thecreation of a digital terrain model originating from surface laser scanning, GPS measurements, a geodetic survey and existing data sources. This more precise mapping of the surface is required in order to estimate the wind flows over a temporary coal storage site and adjacent slopes. The flow patterns are displayed together with aerial images in the GIS for assessment of potential erosion fields over the stockpiles, and for an evaluation of environmental impacts.
