Abstract

A general analytic expression for the two-dimensional dust concentration is obtained. In the case of a constant source strength the solution takes a particularly simple form. It is shown that the one-diemnsional result derived previously for the vertical transport of dust can easily be deduced as a special case of this expression. The profiles of the concentration above the roughness height are evaluated numerically and are found to depend strongly on downwind positions and on wind speed. The numerical values of the concentration at a particular downwind position are found to be smaller than those predicted by the one-dimensional theory. -from Authors
