Determining the link between permafrost and displacement rates of large unstable rock-slopes (LURSs) is fundamental for understanding future hazard scenarios establishing appropriate management strategies. From an inventory >500 LURSs in Norway, we investigate controls those with available information on their (299 LURSs), presenting first statistical evidence as main driver LURSs. The probabil...

This study employs a diverse set of variables to explain slope stabilization on stable versus failure-prone revegetated cut-slopes in Korea. A field survey was conducted at potential unstable sites and stable sites using 23 variables. Through a non-parametric test of the field survey results, 15 variables were identified as primary determinants of slope failure. Of these variables, one describe...

Monitoring unstable slopes with terrestrial laser scanning (TLS) has been proven effective. However, end users still struggle immensely with the efficient processing, analysis, and interpretation of the massive and complex TLS datasets. Two recent advances described in this paper now improve the ability to work with TLS data acquired on steep slopes. The first is the improved processing of TLS ...

Several tests have been proposed in the past for evaluating snow stability. However, their performance is presently unclear since few comparative studies have been done. During winter 20072008 we have collected a dataset of 146 snow profiles, consisting of snow stratigraphy, a rutschblock test (RB), one to two extended column tests (ECT) and in most of the cases also one to two compression test...

In this paper, Feature Engineering (FE) was applied to Landslide Susceptibility Mapping (LSM), while the most suitable conditioning feature dataset and analysis method were tested analyzed. Tianshui city taken as study area, three types of geohazard (collapse, landslide, unstable slopes) used, a total twenty-three features generated; two dimensionless methods (normalization standardization) aft...
