ABSTRACT
Wind erosion refers to movement of soil by wind and is most common in arid and semiarid regions but occurs to some extent in subhumid regions too. Wind erosion has both on-site and off-site impacts. The wind erosion involves three sequential processes, namely surface creep, saltation, and suspension. The erodibility of soils depends primarily on the soil texture or relative proportion of sand, silt, and clay, water holding capacity, structure, and degree of water dispersion within the soil grains. Wind erosion can also take place in high-rainfall climates during particularly dry months of the year in case if the soil is filled with techniques that crush the soil surface to fine particles. Vegetation plays an important role in entrainment and transport of sand by the wind. Both airborne and orbital sensor spectral measurements have been used for wind erosion assessment, monitoring dune dynamics, and wind erosion modeling.
