Floodwater spreading role in reducing the effects of wind erosion in arid and semi-arid regions

Desertification control, especially using the floodwater spreading methods is a logical way that not only 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 analyzing the results of the research projects. The results show changing the texture of the soil to the medium texture, decreasing of pH about 8 percent, increasing the organic matter 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 of silt, clay and organic matter was caused increasing soil moisture therfore connected to the soil and stable against wind power, 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 country without the tree planting. To search for a method to inhibit the effects of wind erosion, measure the amount of soil lost in the water spreading systems is recommended.
