Control of soils wind erosion particularly in arid and semi-arid regions has been seriously paid into attention due to several causes including to prevent the destruction natural resources, reducing air pollution, reducing aerosol transmission and the problems it causes in transportation. Measurement of factors affecting on wind erosion in field conditions is difficult and uncontrollable. Hence, use of wind tunnel device is addressed as one of feasible methods. In fixed wind tunnels, in order to measure soil erosion, trays containing soil shall be placed in the tunnel floor and the wind blows with a given specification. Tray weight difference between the two times of weighing indicates erosion rate of a given level. In present research, wind tunnel was manufactured and launched in laboratory. Wind speed in the tunnel is in 0-40 km/h range. Experimental results showed that the rate of soil erosion and loss is reduced with increased other soil particles versus wind erosion. General and localized erosion phenomena on soil surface were investigated according to soil particles size and uniformity of the samples coating surface.
