Analytical Model of Landslide Risk Using GIS
This paper presents a model for quantitative risk analysis with the application of geographic information systems (GISs) using Bayesian theory. It was used for the thematic integration of maps in a natural state (vegetation, geological-geotechnical, natural drainage and gradient). A landslide susceptibility map was produced based on this integration associated with vulnerability data (time and ...
متن کاملApplication of Artificial Neural Network in Study Phenomenon of Landslide and Risk Modeling using Geographic Information System (GIS), Case Study: Alamoot Rood Watershed
One of the natural disasters that occurs in abundance in Iran, due to the geological structure, morphological and seismic conditions, and damages the lives and property of people is a landslide. Roodbar Alamoot watershed in the east of Qazvin province is a mountainous region with a high potential for occurrence of landslides. Because of their active status, there is also a growing trend of...
متن کاملLandslide Catastrophes and Disaster Risk Reduction: A GIS Framework for Landslide Prevention and Management
As catastrophic phenomena, landslides often cause large-scale socio-economic destruction including loss of life, economic collapse, and human injury. In addition, landslides can impair the functioning of critical infrastructure and destroy cultural heritage and ecological systems. In order to build a more landslide resistant and resilient society, an original GIS-based decision support system i...
متن کاملlandslide hazard assessment using information value and lnrf models
the main purpose of this study is landslide hazard assessment the ziarat watershed (golestan province) using information value and lnrf models within geographic information. at first stage, a landslide inventory map was prepared in the study area using earlier reports and aerial photographs, and a total of 50 landslides was mapped and out of which 35 (70%) were randomly selected for building la...
متن کاملDetermination of the displacement rate of the Masouleh landslide for management of landslide risk by Radar Interferometry
One of the most common natural phenomena occurring in mountainous regions of the world is landslide which causes critical damages and is considered as a natural disaster. Iran is a country which annually suffers from this disaster and its consequent damage of about 500 billion Rial. Over the last 15 years, an increasing number of researches have aimed to demonstrate the applicability of the im...
