In this research, logistic regression analysis was used to create a landslide hazard map for Sajaroud basin. At first, an inventory map of 95 landslides was used to preduce a dependent variable, which takes a value of 0 for absence and 1 for presence of landslides. Ten factors affecting landslide occurence such as elevation , slope gradient, slope aspect, slope curvature, rainfall, distance fro...

The landslides impose serious damages to the economy, environment and human throughout the world. Identification of areas susceptible to landslides is necessary to avoid risks. In This research for Landslide hazard zonation in sarkhoon karoon watershed have been used Shannon’s Entropy Index and Information Value Methods. For this purpose, at first, landslide locations were identified using...
Rock falls are natural process of activities geomorphic on steep slopes in mountainous terrains. At this research, rock fall susceptibility mapping was generated by logistic regression (LR), frequency ratio (FR) and analytical hierarchy process (AHP) at a long 11 km of the Salavat Abad road in the eastern of Sanandaj, Kurdistan, Iran. Dependent variables is occurrence and non-occurrence of rock...
While in recent years, due to numerous reasons, the amount of travel and tourism has increased, the amount of problems caused by this activity is also considered by managers. By using presence points of tourists in Javanrud County, Analytic hierarchy process (AHP) and Random Forest (RF) models, the conditions of establishment of tourists from the aspect of land use planning was investigated. In...
The selection of municipal solid waste landfills is significant because it controls environmental pollution and its problems. Since site selection is a time-consuming and multifaceted process involving various socio-economic and environmental parameters, it requires expert opinion, extensive information resources, and multi-criteria methods. Therefore, this study was carried out for landfill si...
Evaluating and comparing the performance of Frequency ratio coefficient models and network analysis in Rock fall zoning (A case study of Zanjan-Taham-Tarom Road) Extended Abstract One of the natural hazards of the collapse of rocks from the foothills of the mountains, causing great financial losses and loss of life. Especially when it comes to the path of communication. The rock fall is a ...
