Landslide Susceptibility Mapping for Railway Slopes Using Comparative Models and InSAR-Based Validation

Abstract We evaluated landslide susceptibility along the Carajás Railway in Brazil using five approaches: Random Forest, Extreme Gradient Boosting, Multilayer Perceptron, Support Vector Machine, and Weight of Evidence. The models integrated an inventory of 148 landslide events wi...

Long-Term Seepage and Stability of Tropical Railway Cut Slopes Using Satellite Hydroclimatic Data

Abstract Rainfall-induced landslides threaten tropical railway infrastructure, where sparse monitoring limits the characterization of rainfall–instability relationships. This study investigated the long-term hydraulic response and stability of railway cut slopes in residual soils...
