Abstract: Wind erosion is a widespread phenomenon causing land degradation in arid regions. The capacity of nanoclay in soil erosion control has been assessed in wind tunnel experiments as a novel technology. To study the effect of nanoclay on stability of sandy soils against wind erosion, a laboratory research program was set up in wind tunnel. The soil samples were treated with distilled water as control and nanoclay at a rate of 2000 ppm were uniformly spread on the soil surface. The treatments were performed in the condition with wind velocity of 31.0, 55.2 and 67.3 km h^–1. The results showed that soil volumetric water content at 300 kPa increased (about 18.9%) with application of nanoclay. There was a positive function between the erosion amount and soil moisture content in the treatment of soil with nanoclay. The soil erosion amount decreased (more 99%) with the application of nanoclay. The proportion of 0.25-2 mm fraction increased (2.5%) and the proportion of 0-0.25 mm fraction significantly decreased (74%) with use of nanoclay. As a result nanoclay is able to fixate the sand and it has ability to stabilize the soil structure, increase aggregation and of course decrease soil erosion.
