Estimating the sediment production potential caused by wind erosion in Abdolkhan lands (Shuosh) Using IRIFR
Abstract:   (597 Views)

Determine the relative susceptibility of land to wind erosion and its effective factors in order to prioritize and soil conservation management and controlling their effective agents is necessary. In this research IRIFER 1 model had used for determine the potential for wind- generated sediments in the study area, in Ablolkhan region lands. In this study, the model was used IRIFR 1 . 9 defined effective agents investigated and the grades of each part in the area calculated and year-sediment production estimated. The results of current study in investigated region had shown 290.35 ha of 10.21 percent of the total area in the class, 424.7 ha of 14.93 percent in the middle class, 1516.16 ha of 53.34 percent in the class and 611.57 ha of 21.51 percent of the entire region too much in terms of production and the erosion of the wind. Generally, average wind erosion intensity in study area with 79 .55 points, and the average annual sediment production potential in this region with 3302.64 tons per square kilometer per year, had the high (intense) grade of quality. In the effective factors in the erosion of wind speed and operating IRIFR approach, as well as the situation in the context of the soil and the level of the most important factors in the wind erosion and has the potential to produce the sediment studied in the region. Wind factor, wind situation, soil texture and its surface cover were the important effective factor in wind erosion and sediment production potential in the study area between effective factors in wind erosion by IRIFR model
