ارزیابی مقایسه‌ای روش‌های احتمالاتی وزن واقعه و نسبت فراوانی در پهنه بندی خطر زمین لغزش (مطالعه موردی: حوزه آبخیز ونک، اصفهان)
In this study, Vanak catchment because of high sensitivity to landslide was selected. Then with geological, topographic maps and field survey, Landslide hazard map was prepared using GPS as dependent variables. A total of 110 landslides were mapped in GIS out of which 77 (70%) locations were chosen for the modeling purpose and the remaining 33 (30%) points were used for the model validation. Th...
متن کاملValidation of Spatial Prediction Models for Landslide Susceptibility Maps
A wide range of numerical models and tools have been developed over the last decades to support the decision making process in environmental applications, ranging from physical models to a variety of statistically-based methods. In this study, a landslide susceptibility map of a part of Bailongjiang River, in northwest China was produced, employing binary logistic regression analyses. The avail...
