Effects of spatial variations in source areas upon dust concentration profiles during three wind erosion events in Australia

Butler, H. J. and Hogarth, W. L. and McTainsh, G. H. (2001) Effects of spatial variations in source areas upon dust concentration profiles during three wind erosion events in Australia. Earth Surface Processes and Landforms, 26 (10). pp. 1039-1048. ISSN 0197-9337

Abstract

Dust storms are a major contributor to soil erosion in inland Australia, and the Simpson Desert-Channel Country region is one of the most active wind erosion regions. While information is available on wind erosion rates at the land-type level, little is known about the influence spatial variations in the erodibility within a land-type has on the resulting dust concentration profile. A Gaussian plume model, DSIS, is presented along with tower-based dust data, to describe the influence of different spatial combinations of dust sources areas, during three dust events on the Diamantina River flood-plain in Western Queensland, Australia.
