The purpose of this study was to investigate maximum and minimum grain size which eroded by wind according to soil and windconditions, such as top soil water content, roughness, land slope, wind velocity and proportion of grain size under 0.84mm. Forperforming this study, portable wind erosion tunnel was designed and utilized during field test, which facilitated measuring actual winderosions under artificially controlled wind conditions. In the result, maximum, minimum grain size had strong negative correlation withroughness while weak positive correlation with wind velocity. Also, Slope which means the effect of gravity also influence grain sizeerodible by winds. Based on these results, regression equations were suggested for predicting maximum and minimum grain sizes byusing multiple linear regression analysis from SPSS 20.0. The equation for maximum grain size erodible by winds showed a goodagreement with the observed data with R2＝0.896. Other equation for minimum grain size had R2＝0.777.
