The present study shows that very low erosion class (0.23 to 8 tons per hectare per year) Romeshgan watershed, most of the area to be included in the attrition levels low, medium, large and have too much. In general we can say the area is low to moderate ability erodible. SLEMSA model for estimating erosion, environmental conditions are examined. These factors in watershed erosion rates in diff...

Extended abstract 1- Introduction Soil erosion is one of the most important problems in the arid and semi-arid areas in Iran and the knowledge about its content has an important role on the management practices of soil conservation. Topography as one of the soil-making factors affects the physical properties of the soil through the aspect and the degree of the slope. The aspect of the slope c...
