This chapter reviews some of the methods used for investigating basic processes and conditions affecting wind erosion. E. L. Skidmore and J. Tatarko developed a wind data base suitable for use in the stochastic approaches in the wind erosion modeling

Soil Erosion and Crop Productivity
Wind erosion is a serious problem in portions of the USA and becomes more widespread and severe during droughts. Wind erosion can become a major problem whenever the soil is loose, dry, finely divided, bare or nearly bare, and the wind velocity excee

Standard dust sampling equipment was used to collect eroded aerosol samples from 52 wind erosion events in the Northwest Coastal Zone (NWCZ) of Egypt. The eroded samples were analyzed to determine the transport mass for each erosion event over a 3-ye

Standing vegetation, for its disturbance to the near-surface airflow, is widely used in the arid and some semi-arid lands over the world to control wind erosion. Knowledge of drag coefficient ( C D ), roughness length ( Z 0 ) and displacement height

Knowledge of the aerodynamic roughness length (Z0) resulting from management practices that include soil clods, vegetation, and ridges is essential to describing their protective roles in wind erosion. The usual method of obtaining Z0 from a logarith

We hypothesized that drought accelerates wind erosion by increasing plant and soil factors of erodibility together, compounding the erosion hazard. Erodibility factors measured in biennial spring wheat-fallow on Pachic and Typic Haploborolls soil wer

The Takla Makan Desert is one of the supposed sources of eolian deposits in the eastern China and the North Pacific Ocean. Lack of direct measurements hinders the theoretical interpretation of material exchange between the atmosphere and land surface

Our understanding of the physical mechanisms of wind erosion and dust emission stimulated by disturbance of surface soils is not adequate, even though it is a problem leading to desertification in the arid zone. Simulations of the influence of surfac

A Single Event Wind Erosion Model (SEEM) has been developed and tested with field erosion data. Estimates ofmass transport and critical field lengths are possible with SEEM when given simple inputs for soil, crop, field, and weatherconditions. With t

A field experiment at Owens (dry) Lake, California, tested whether and how the relative profiles of airborne horizontal mass fluxes for >50-μm wind-eroded particles changed with friction velocity. The horizontal mass flux at almost all measured heig
