Dust deposition samplers were constructed from inverted flying disks attached to unilets and electrical conduits. Wind tunnel tests showed a fine screen placed over a porous mat in the bottom of each sampler was necessary to prevent blowout of trapped dust particles. Twelve samplers were installed along 3 transects near a vegetated surface within 200 m of a 6-ha bare, Amarillo fine sandy loam, source field at Big Spring, TX. Dust deposition data from individual storms were collected for 3 erosion seasons. Both particle size and deposition mass of dust decreased with distance from the source field. Model predictions of dust deposition were compared to measured for a number of erosion events. Based on these results, estimates of pollution potential from dust deposition near source fields are discussed.
