  The studied region with 3750 km² is located in 65 kilometers in south-east of Tehran and 140 kilometers in westof Semnan. In this study, physical and chemical characteristics and engineering marl which are sensitive toerosion with various forms of Surface, Rill, Gully, and Channel Erosion have been investigated. It was taken 14samples of marl surface with mostly Gully Erosion. The results of chemical analysis showed that the soil of thisregion is salin,alkali soils, from the viewpoint of engineering, soil samples within the SM, SW, SP, and SCM areconsidered. The granulometrie of soils showed that they are loamy to fine loamy. So they are susceptible toerosion. According to analysis to detect physical properties, chemical and mechanical engineering marl markedbetween amounts of salt, gypsum and lime are significant differences and these three factors can be an importantfactor in distinguishing erosion problems considered.
