Abstract
ABSTRACT The article describes an original conceptual model that intends to explain the emission mechanism of Particulate Matter from the surfaces of tailing basins exposed to wind erosion. In order to estimate the site-specific parameters of the Emission Factors in the proposed model, the reproduction of the wind flow acting over the erodible surfaces becomes essential. Based on the parameters determined on site and assumed as project objectives, an Environmental Wind Tunnel has been designed to generate a part-depth Atmospheric Boundary Layer (ABL). The measurements performed in the tunnel proved the simulated wind profiles to be representative of the required ABL.
