TL;DR: In this paper, the analysis of a turbulent boundary layer saturated with saltating particles was carried out in a wind tunnel 15m long and 0.6m wide at the University of Aarhus in Denmark with sand grains 242 μm in size for wind speeds ranging from the threshold speed to twice its value.

Effects of grazing and topography on dust flux and deposition in the Xilingele grassland, Inner Mongolia
TL;DR: The dynamics of dust emission and deposition in the grasslands of Inner Mongolia were investigated during a measuring campaign from April to May 2005 in grazed and un-grazed plots, finding that leeward slopes had 29–33% higher deposition rates than windward slopes, summits and plane positions.

Aeolian sediment transport over vegetation canopies: a wind tunnel study with live plants
TL;DR: In this paper, a wind tunnel study examines aeolian sediment transport in live plant canopies, whereas most previous studies have used model plants for this purpose, and experiments were performed with three canopy densities of Perennial Ryegrass ( Lolium perenne ) and with bare sand surfaces.

Vertical variation of particle speed and flux density in aeolian saltation: Measurement and modeling
TL;DR: In this article, particle dynamics in aeolian saltation has been studied in a boundary layer wind tunnel above beds composed of quartz grains having diameters of either 242 μm or 320 μm.

Protocols for Characterizing Aeolian Mass-Flux Profiles
TL;DR: In this article, a protocol for characterizing and analyzing the vertical mass-flux profiles above erodible beds in natural aeolian environments is described, which is physically based, produces results that most closely represent the measured data, and will permit results from different field and laboratory studies to be compared using a standardized convention.

Wind modification and bed response during saltation of sand in air
Robert S. Anderson,Peter K. Haff +1 more
TL;DR: In this article, a model of eolian sediment transport was constructed, which is a special case of sand-sized mineral grains subjected to moderate winds: saltation, and the model consists of four compartments corresponding to aerodynamic entrainment, grain trajectories, grain-bed impacts, and momentum extraction from the wind.

Saltating particles over flat beds
TL;DR: In this article, the authors measured ejection and impact velocities, trajectory lengths and maximum rise heights of sand grains (median diameters 118 and 188 μm) in saltation over a flat sand bed in a wind tunnel.
