Abstract

gully erosion is types of water erosion that its occurrence and development lead to the loss of fertile agricultural soil, depletion of soil and groundwater. The objectives of this study were to investigate gully erosion and determine the sensitive areas in terms of gully erosion on the Sorkh Abad Watershed. Information layers such as slope, land use, distance from faults, aspect, distance from the stream network, distance from roads, lithology, rainfall and altitude above the mean sea level were prepared, classified and weighted using the Arc GIS software. Analytic network process (ANP) was used in the data analysis and modeling. The DEMATEL method was used to design the network structure among the criteria. The receiver operating characteristics (ROC) and the area under curve (AUC) were used for Validation of the gully erosion map. The results indicated that four criteria: distance from roads, lithology, land use and precipitation were the most important factors leading to cause gully erosion. The results of Validation of the gully erosion zonation map showed that the AUC with 0. 684 had an appropriate function to determine susceptibility of the localities to gully erosion in the studied watershed.
