A MaxEnt-TRIGRS hybrid model with dynamic safety factor mapping for enhanced debris flow susceptibility assessment in rainfall-triggered terrains [PDF]
Scientific ReportsTraditional statistical models for debris-flow susceptibility often overlook critical triggering mechanisms and geotechnical parameters. To address this, we propose an innovative framework that couples the Maximum Entropy (MaxEnt) statistical model with ...

Spatial transferability of the physically based model TRIGRS using parameter ensembles
Earth Surface Processes and LandformsCalibrations of the physically based slope stability model TRIGRS were derived and compared for two study areas in the Eastern Alps. The comparison shows high similarities in the calibrated values of the geotechnical parameters, but differences in the hydraulic parameters.

The importance of unsaturated soil properties in the development of slope susceptibility map for Old Alluvium in Singapore [PDF]
E3S Web of Conferences, 2023 Slope failures caused by rainfall are a regular occurrence in residual soils. As a result of climate change, increased precipitation is anticipated; preventing slope failures due to rain is therefore essential.

Improving predictive power of physically based rainfall-induced shallow landslide models: a probabilistic approach [PDF]
Geoscientific Model Development, 2014 Distributed models to forecast the spatial and temporal occurrence of rainfall-induced shallow landslides are based on deterministic laws. These models extend spatially the static stability models adopted in geotechnical engineering ...
