WebbAeolian sand transport is one of the main processes that causes soil loss in arid and semi-arid regions. Sand particles can be mobilized by the shear force created by the wind, which causes more particles to enter the airflow in response to both the force of the wind and the impacts from saltating particles. A quality‐controlled data set comprising measurements of aeolian sand transport rates obtained at three disparate field sites is used to evaluate six commonly employed transport rate models (those of Bagnold, Kawamura, Zingg, Owen, Hsu, and Lettau and Lettau) and to recalibrate the empirical constants in those models.
