Abstract

One of the geomorphologic issues that many human activities affect is the LANDSLIDEs. Natural factors and human activities on the other hand, these events are triggered. LANDSLIDE one of the most active hazards are natural processes that lead to erosion and changes in the landscape. Iran is a predominantly mountainous topography, seismic activity and high LANDSLIDE, diverse climatic and geological conditions of natural conditions for a wide range of slip is important. Located in second place in the sector of industry, population of 1695094 people, proximity to major faults of TABRIZ and occurrence LANDSLIDEs of different city of TABRIZ, the city has become one of the most dangerous cities in the environmental hazards, especially LANDSLIDE. In these circumstances and completed a comprehensive review and a detailed zoning of land for LANDSLIDE susceptibility seems absolutely necessary. The purpose of the present paper, the occurrence of LANDSLIDE susceptibility assessment and mapping potential occurrence of LANDSLIDEs in the city of TABRIZ in this range. This research of the type applied- development research and of the research method is descriptive - analytic. In this study, using a variety of sources including satellite imagery, aerial photography, global positioning system (GPS) and field studies LANDSLIDE occurred in the study area were identified and these data were analyzed using the software ILWIS and use of library studies and expert opinions should identify the criteria and sub-criteria and range were classified. Then, using fuzzy TOPSIS model, the importance of the criteria and sub-criteria specified in pixel units and finally combining fuzzy-TOPSIS model and overlapping functions in ARC / GIS final map was extracted. Geomorphologic and lithology conditions of the city with its mountainous location where the trigger LANDSLIDEs. The final results indicate that over 30% of the areas of the city of TABRIZ are medium to high risk that this areas of land in the north and northeast is sparse. The accuracy of the final map and the map of the distribution of faults and the accuracy of the study proved to be that hazardous zones roughly corresponding to the final map lapses occurred. So we can conclude that the method and the model presented in this paper is an effective method for LANDSLIDE hazard zonation within the cities.
