Abstract

An analysis of saltation data led the AA. to modify the theory of P.R. Owen using a soil-related parameter "A" that gave them the possibility of expressing limitation of sand grains of saltation-size in the underlying soil. The value of "A" was set equal to the ratio of the horizontal flux of saltating particles to Owen's function of wind, times air density by gravitational acceleration. Values of "A" can be used to : 1) characterize the efficiency of the wind to move sand by saltation for different soil textures and aggregations; and 2) to make practical predictions of sand movement based on the condition of the surface soil. An increase of "A" usually corresponds to soil changing from an aggregated state to a looser state
