Abstract :
Gully erosion is development form of water erosion that that effects of natural and human factors of the imbalance comes. Rural Settlements and Infrastructure causes irreparable damages to be created. Purpose of this study, identified Rural settlements risk is using the fusion model fuzzy - Ahp. The total of nine natural factors that are contributing in Gully event was used in this model and Gully erosion hazard map of Rude- kar-kar river basin was developed using geographic information system and ArcGIS 10 software. Resultant data was checked by field observations and results of previous studies.Results showed that 92 villages at north and south of catchment are located in areas with very high and high risk of flood because of their topographic location. The total of 66 % of catchment area were classified in very high to high risk of gully erosion, which point out that the study area is encountering severe gully erosion hazards. In addition, application of FUZZY-AHP model and method of this resaerch is firmly recommended to be used for planning of gully hazards for human settlements at other parts of Iran.
