Desertification control, especially using the floodwater spreading methods is not only a logical way for rehabilitation of groundwater reservoirs, but also improves some severely degraded lands because of suspended load in floods. In this essay, the descriptive-analytic method was used by library method and the results of the research project were analyzed. The results show changing the texture of the soil to the medium texture, decreasing of pH about 8 percent, increasing the organic materials about 6 times, increasing the vegetation that all of them have the significant effect on the reducing of the wind erosion due to floodwater spreading projects. Increasing silt, clay and organic materials are lead to increase the soil moisture; therefore the integrated soil will be more stable against wind erosion, which reduces the corrosive force of the wind. So, flood water spreading will also play an important role in reducing of wind erosion in arid and semi-arid of the country (Iran) without the tree planting. Searching for a method for inhibiting the effects of wind erosion and measuring the amount of soil lost in the water spreading systems is recommended.
