Abstract

The increase of soil mass flux with distance downwind, the fetch effect for wind erosion, has been observed and reported on since 1939. The model proposed incorporates 3 mechanisms: 1) the avalanching mechanism in which one particle moving downwind would dislodge one or more particles upon impact with the surface; 2) the aerodynamic feedback effect in which the aerodynamic roughness height is increased by saltation of particles; 3) the soil resistance mechanism, which is largely an expression of the change with distance of threshold velocity. An experiment was run in March 1993 at Owens Lake to test this model
