Recognizing the eroded areas using the surface albedo algorithm of Landsat 8 satellite imagery (case study of basin Jajrood)

Soil is one of the most important natural resources of any country. the erosion causes not only the depletion of the soil and the loss of the land, causing great and irreparable damages, but also with the deposition of materials in streams, reservoirs, ports, and reduced pool capacity. Therefore, it should not be underestimated. In this study, we identify and zoning of the erosion areas in the basin of jajrud river basin. For this purpose, landsat 8 satellite imagery of landsat 8 / 8 / 2016 and digital elevation model were used and surface albedo were calculated for the study area and classified into five categories. the results showed that the area of 14677.30 hectares of land area has high erosion conditions that most of these areas are located above the dam and are considered a threat to the reservoir.
