Abstract

The effect of rock fragment cover on the deposition of airborne dust was examined in a wind tunnel. Four parameters were studied: pebble size, pebble flattening, cover density and wind speed. The effect of these parameters on the deposition of dust on the pebbles, on the deposition of dust between and underneath the pebbles, and on total dust deposition was measured separately. Air flow separation seems to play a primary role in the spatial distribution of dust deposition within a rock fragment field, as it determines the location and size of the low-sedimentation areas that are connected to the air flow separation bubbles
