Abstract
Wind Erosion is a serious problem in arid and semiarid regions of the world. Numerous studies have focused of the small-scale physical processes involved in sediment entrainment thresholds and the subsequent transport and deposition of sediment by wind. From this body of work an understanding of the climatic and terrestrial factors influencing wind erosion have been described mathematically. Models integrating these factors have been developed to estimate soil erosion and dust emission from areas ranging in scale from farm fields to continents. However, models are in constant need of improvement as new information appears and concepts develop. Although it is well understood that the presence and distribution of vegetation plays a role in reducing wind erosion, how best to describe that role in large scale applications is still at issue. Recent work has revealed the strengths of Raupach's approach to modeling shear stress partitioning at the large scale. This work presents an integrated model of dust emission and wind erosion utilizing this approach at the regional scale.
