Comparing 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 کاملAn easy-to-use MATLAB program (MamLand) for the assessment of landslide susceptibility using a Mamdani fuzzy algorithm
In this study, landslide susceptibility mapping using a completely expert opinion-based approach was applied for the Sinop (northern Turkey) region and its close vicinity. For this purpose, an easy-to-use program, ‘‘MamLand,’’ was developed for the construction of a Mamdani fuzzy inference system and employed in MATLAB. Using this newly developed program, it is possible to construct a landslide...
متن کاملLandslide Risk Assessment for Baba Heydar Watershed, Chaharmahal and Bakhtiari Province, Iran
Landslides are among the most damaging natural hazards in mountainous regions. In this study, landslide hazard zonation was conducted in the Baba Heydar Watershed using logistic statistical regression to determine landslide hazard areas. First, a landslide inventory map was prepared using aerial photograph interpretation and field surveys. Next, ten landslide conditioning factors including alti...
متن کاملPresentation of new ensemble method of Bayesian and logistic regression models in landslide susceptibility assessment in the Khalkhal Township
The aim of current research is to assess of landslide susceptibility in the Khalkhal Township, southern Ardabil using an ensemble and new method namely Bayesian and logistic regression (BT-LR) models. At first, landslide inventory map was prepared and then effective factors on landslide occurrence were identified. These factors are slope degree, plan curvature, slope aspect, elevation, landuse,...
متن کاملاولویتبندی عوامل موثر بر وقوع زمینلغزش و تهیه نقشه حساسیت آن با استفاده از الگوریتم نوین جنگل تصادفی (مطالعه موردی: بخشی از استان گلستان)
Landslide as a natural hazard is very dangerous especially in mountainous areas that result in loss of human life and property around the world. Iran is always exposed to landslide hazard especially in the north and west because of climatic and topographic conditions. The aim of this research is prioritization of landslide-conditioning factors and its landslide susceptibility mapping in the par...
