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.
