  Soil erosion is one of the major environmental concerns of the present century. This issue has become a major problem to the environment and natural resources, so that statistics indicate that soil erosion in Iran is several times more than global average. This research was carried out with to investigate the factors affecting the Varak area erosion and its risk zonation using the EPM method. For this purpose, field visits and satellite images studying were used to investigate the erosion. Then, the information layers of the area including average slope, soil and rock susceptibility to erosion, land use and observational erosion were prepared, and information layers were weighted and the erosion risk susceptibility map was prepared. In addition, the results from the risk zonation of the region show that 6.3, 55.2, 26, 3.1 and 9.4 percent of the region are at the erosion risk classes of very low, low, moderate, severe, and very severe, respectively. Based on the zoning, the focus of the erosion-sensitive areas are in the southwest, northwest, and a part of the north of the region, which is consistent with the fossilized and fractured parts of the Asmari lime, which has a higher slope. Considering the field observations, investigating the precision measurement of the method used to prepare the potential erosion risk map of Varak watershed indicates that the EPM method has a fairly high precision.

  Basins in terms of geology, climate and other factors on the roughness and erosion are very different, the aim of this study was to evaluate Navrood watershed erosion, erosion rate, sediment yield and factors in the relationship between the physiographic features, topography, climate, geology, geomorphology, vegetation, soil erosion is generally determined. The basin has an area of about 265/46 square kilometers. The aim of this study was to evaluate the erosion and sediment production in the watershed and to find the sensitive areas of erosion. To achieve the above objective, the erosion potential (EPM) was used for data collection. The data collection tools, aerial photos, map types, methods and library sources are observed. In this study, using EPM (Erosion Potential Method) erosion rate in each sub-basin (sub-basin 11) has been investigated. In relation to the regional geomorphologic outcrop s is composed of 15 types. By integrating them into the structure of the slope, lithology and resistance to wear and combine them work units respectively. The erosion rate and sediment production in each experimental work units using EPM (quantitative) took place. Based on the results obtained, the following basins 4 and 5 of erosion is most severe erosion (erosion rate of 0/24 and 0/22). The highest sediment than the other sub-basins have been allocated. Because of the large number of specific erosion and deposition in the sub-basin, sub-basin compared to other high slopes and rock sensitivity to erosion, Switch, grassland and forest degradation, road-building.
