Advanced numerical modelling

We have recently developed a new depth-averaged, GPU-based runout model named “ORIN-3D”. This model has dramatically improved the runtime and simulation resolution that can be obtained using equivalent fluid type runout models. We have applied this and similar models to understand the mechanisms governing rock avalanche runout, as well as to understand flowslide and debris avalanche behavior.

We have performed forensic back-analysis of a large number of case histories, both to better understand the mechanisms detailed above, and to provide guidance for forecasting runout potential. In line with this latter goal, we are actively working on developing probabilistic methods for evaluating landslide hazard and risk.  

We have developed a fully implicit particle finite element method (PFEM) framework that can capture the initiation, evolution and consequence of slope failures across multiple temporal scales. The model contains various components for realistically simulating landslides, such as strain-softening models, damage mechanics models, micromechanical model, fault zone models, etc. The PFEM can serve as a basis of the development of advanced geoscientific models for predicting the entire landslide process in practice.
