عنوان انگلیسی Estimate potential sediment yield In Shadegan Catchment with using of IRIFER and hierarchical models
چکیده انگلیسی مقاله Soil erosion is a major problem for developing countries with arid and semi-arid climate. These of erosion Is possible than two ways of water and wind. In this paper, with using of two methods irifer and hierarchical models, The rate and intensity of of soil erosion is estimated Shadegan Catchment. For this purpose, By using various maps alike DEM, rainfall, land use index, NDVI, Geology estimated Rate and intensity of soil erosion in GIS. Then final map erosion estimation Obtained from two methods were classified into five groups, very high ,high, medium, low, very low , results showed that About 12.2% of the watershed area of erosion is high and very high. And average soil erosion in the catchment area of 2143.8 Ton / Hectare / Year. In this Catchment Viewpoint erosion is crisis conditions and very severe. According to Correlation 0.96 was calculated regression equation In this research showed that AHP methods combined with use of GIS Procedures and tools for estimating, Display and Classification is Rate Soil erosion However In this respect also can be used recent methods.
