Abstract:
Unregulated or unprofessional land development and land use management in mountainous regions
with steep slopes has led to increased instances of landslides causing human losses and damage to
urban facilities. This phenomenon also has numerous indirect environmental impacts such as the
destruction of rangelands and forests, and creation and transportation of sediments that might fill or contaminate the artificial and natural reservoirs. It is obvious that any of these events can have grave consequences for urban macromanagement system and can be considered a managerial crisis. Therefore, the identification of areas susceptible to landslides and creation of a comprehensive, efficient and updatable database to prevent or properly manage this natural disaster is essential for an adequate natural resource management and effective construction and development planning. Landslide susceptibility mapping is one of the most important strategies for reducing the damage caused by landslides. There are several approaches to this strategy, but all these approaches require creating a comprehensive database composed of data concerning the factors contributing to the magnitude or probability of landslide. This paper introduces and discusses the effective methods for collecting the GIS data describing the landslide susceptibility factors.

Science and Research Branch, Islamic Azad University, Tehran, Iran *Corresponding Author ABSTRACT Unregulated or unprofessional land development and land use management in mountainous regions with steep slopes has led to increased instances of landslides causing human losses and damage tourban facilities.
In this paper, ArcGIS software is used to collect and process such factors including geology, distance from lineaments, slope, aspect, precipitation, and elevation in the study area.
Shahabi and Najafi UCT Journal of Social Sciences and Humanities Research 5-1- Distance from faults Geological structure is one of the essential factors affecting the probability and magnitude of landslides in an area.
The process of landslide susceptibility mapping requires the researcher to use that software to prepare and digitalize several maps describing the status of slopes and their aspects, elevations, land use, distance from fault, distance from channels, distance from roads and geology of the studied area.
