Abstract
This study investigates the origin of wind sediments by using a tracing method and providing strategies for coping with their risk in the railway line of Tehran-Zahedan (case study of Shurqas and Rudshur stations).The method used in this study was analytic and using F statistics, we determined the affected components.The main hypothesis in this research is that using the fingerprinting and tracking method, it is possible to identify the source of wind sands entering the area between the Shurqas station and Rudshur.SPSS and Arc GIS software were used to analyze the results. The study area in this study is Shurqus and Rudshur stations.The findings of the study indicate that among the components studied, the origin of the sediment was the highest relative importance of reducing vegetation density, with a relative significance of 10.36, followed by drought for relative importance of 4.51 The second rank is followed by the monsoon winds with a relative significance of 1.81, and finally the seasonal flows with a relative importance of 1.6 have the highest rank in determining the origin for wind sediments. Also, the statistical test of the ability of the detectors to differentiate the sediment resources showed that sodium element with the F-value of 3.78 had a significant effect on the separation of the sediment yield and also the copper element with the F-value of 1.01 and the iron element with the F-equation 2.95 has a coefficient of effect on the formation of the separation of sediments from the source.
