الملخص EN

The wind pressure applied to the surface of the soil is closely related to the climatic data prevailing in the region such as high temperature, solar brightness, relative humidity during the summer months which contribute to increasing the evaporation rate and then dry the soil and make it responsive to wind erosion In particular in the southern parts of the study area Represented by al-Hadhar and al-baaj district.

Therefore, the soil erosion process depends mainly on the knowledge of the force of wind pressure on the surface of the earth, the climatic susceptibility of wind erosion, soil susceptibility to wind erosion, And for the purpose of reaching the aim of the research, a number of relevant climatic equations were adopted (wind pressure strength (kg / m2), Zachar wind speed equation, Chepil and woodruff equation recommended by the Agricultural Research Authority of the Ministry of Agriculture America, In addition to collecting 12 models of the surface layer of the soil of the abandoned land and sand dunes within the study area and laboratory analysis in order to know the amount of flours transported by the wind in a quantitative level, Where the percentage of the surface layer content of the soil varied from the flours and the groups resistant to wind erosion less than( 1 mm) in diameter.

The study reached several conclusions and recommendations
