evaluation soil erosion is an important matter to protecting it from destroying in future due to the excessive use of the inherent capacity of soil and also improper management. therefore, in this study land vulnerability related to water and wind erosion of abyek for crops and pasture land has been evaluated, using raizal model as one of the microleis sub-models. morphological and physical and...

In order to recognize the wind erosion situation of a region, the survey of its windiness is not sufficient and the physical characteristics of earth are of importance too. In fact, the outbreak of dust storms in a region is due to the sensitivity of earth and domination of wind in that region. In this investigation we have tried to find a way for determining the regions in which a dust storm i...

The result of wind dynamic (capacity and potential) is transport of soil or sediment particles and subsequent formative desert landforms based on the severity of erosion or sedimentation. The Khartouran region, because of its geology, geomorphology and climatology conditions is a special place in the arid region on the closed basin of Dasht-e-kavir. It is evident that the ecosystem balance of t...

In the United States, the USDA Natural Resources Conservation Service (NRCS) is the primary agency charged with the task of reducing wind erosion associated with production agriculture. The NRCS has used the Wind Erosion Equation (WEQ) (Woodruff and Siddoway, 1965) to assess the effects of field management on the potential for wind erosion for the last two and a half decades. The WEQ uses input...

aeolian landforms are very sensitive to wind erosion. afforestation of degraded sandy land soils is regarded the most effective strategy against wind erosion. the aim of this study is to estimate decreasing in wind erosion rate by afforestation of these landforms. in this research, geomorphological areas have been used as homogeneous units. research data are including scores of petrology, terra...

Potter, K. N., Williams, J. R., Larney, F. J. and Bullock, M. S. 1998. Evaluation of EPIC’s wind erosion submodel using data from southern Alberta. Can. J. Soil Sci. 78: 485–492. Wind erosion models have been used to assess policy impacts on soil erosion, but validation of models has been difficult until recently. We evaluated the Environmental Policy Integrated Climate (EPIC) wind erosion subm...

The wind erosion stochastic simulator (WESS) is a single event wind erosion model that is the core of the wind erosion submodel of the environmental policy integrated climate (EPIC) erosion model. WESS uses inputs of soil texture, erodible particle diameter, soil roughness, soil water content, crop residue, and 10 min average wind speeds to predict the erosion at several user-selected distances...
