Abstract

Surface EROSION MAP is one of the basic maps in erosion and sediment studies which is prepared based on soil surface apparent in an area. For preparing soil surface EROSION MAP, a study was down in Kan-Sologhanand Jajroud basins of Tehran, Iran.Different data layers were integrated in GIS. For this purpose' at the first stage, working unit maps were prepared from: A) plant cove, geology and slope B) land-use, geology and slope C) land-use, rocks resistance to erosion and slope and D) land-use, rocks resistance to erosion and resources evaluation and lands capability (land units) in Kan-So10ghan basin. For comparing the effectiveness of 4 working unit maps, 53 control points were investigated. Results showed that maps A, B and approximately map C are not suitable maps for differentiating soil SURFACE EROSION. Map D include of 6 units in which 66.6 and 78.5% of control points had the same intensities of SURFACE EROSION in two units and had similar SURFACE EROSION in other four units. At the second stage, D working units map was compared with three other maps of E) land units F) rocks resistance to erosion and G) image photomorphic in a broader basin of Jajroud.Surface erosion intensities in 314 control points were controlled and actual surface EROSION MAP was prepared by Thiessen method and using satellite imagery. Surface EROSION MAP was crossed with different working unit maps. Results showed that the highest ACCURACY was related to the images with 86.4% ACCURACY applicable to actual SURFACE EROSION. ACCURACY was 78.9, 66.1 and 59.1 percent for methods of D, E and F, respectively.Root Mean Squared Error was highest for rock resistance map and the least for images interpretation method. The greatest PRECISION was related to image interpretation with coefficient of Variation of 19.9%, while land units map had the highest coefficient of variation of 38.8%. This was 26.2 and 35.9 percent for of integrated layers and rock resistance maps.
