Abstract

Estimating the amount of Wind Erosion in the plains of Iran is the most important requirement for planning and selecting appropriate methods of erosion control. Two approaches including IRIFR1 Model and Wind Erosion meter were used to measure and estimate the erosion and deposition potential in the Segzi Plain of Esfahan. Initially, different landforms of the Segzi Plain including coarse grain plain, medium grain plain, and fine grain plain were detected. In order to measure the deposition potential, initially in each of the landforms per different wind speeds, the amount of soil erosion was measured within an hour using the Wind Erosion meter. The continuity of wind blowing for each wind speed class was estimated by analyzing the wind roses of East Isfahan station during the year. Finally, the erodibility rate of each landform was determined by integrating the multiplication of the continuity of each wind speed class and erodibility. In order to use the IRIFR1model, while visiting the desert, the scores of each index were given to the landforms and the deposition potential was estimated. The results showed that the amount of Wind Erosion of each studied landforms from coarse reg, average reg, fine reg and very fine reg were 2, 13. 2, 21. 3 and 74. 1 ton/ha/yr, respectively. On the other hand, the values obtained from both models show differences of 5% to 30% in different landforms. The average amount of deposition obtained from IRIFR1 is about 11% less than the values obtained from Wind Erosion meter.
