landslide also referred to as mass movement, slope failures, slope instability, and terrain instability is the mass movement, usually sudden, of soil and debris down a steep slope (Cruden, 1991). They are caused by a variety of factors such as heavy rains, earthquake ground shaking or geological forces. Different types of landslides move down slope at a wide range of speeds (Varnes, 1978). Most...
متن کاملProbabilistic Prediction Models for Landslide Hazard Mapping
A joint conditional probability model is proposed to represent a measure of a future landslide hazard, and five estimation procedures for the model are presented. The distribution of past landslides was divided into two groups with respect to a fixed time. A training set consisting of the earlier landslides and the geographical information system-based multi-layer spatial data in the study area...
متن کاملComparing Bivariate and Multivariate Methods in Landslide Sustainability Mapping: A Case Study of Chelchay Watershed
1- INTRODUCTION In the last decades, due to human interventions and the effect of natural factors, the occurrence of landslide increased especially in the north of Iran, where the amount of rainfall is suitable for the landslide occurrence. In order to manage and mitigate the damages caused by landslide, the potential landslide-prone areas should be identified. In landslide susceptibili...
متن کاملValidation of Spatial Prediction Models for Landslide Hazard Mapping
This contribution discusses the problem of providing measures of significance of prediction results when the predictions were generated from spatial databases for landslide hazard mapping. The spatial databases usually contain map information on lithologic units, land-cover units, topographic elevation and derived attributes (slope, aspect, etc.) and the distribution in space and in time of cle...
متن کاملApplication of a Data Mining Model for Landslide Hazard Mapping
This paper deals with landslide hazard and risk analysis using Geographic Information System (GIS) and remote sensing data for Cameron Highland, Malaysia. Landslide locations were identified in the study area from interpretation of aerial photographs and field surveys. Topographical/geological data and satellite images were collected and processed using GIS and image processing tools. There are...
