About the research project

Heavy rainfall and a changing climate have a direct correlation with the frequency of large geohazard events. Heavy rain events are particularly challenging in the mountainous regions of the Tasmanian West Coast Wilderness. Two major categories of geohazards with the potential to cause catastrophic damage to the Tasmanian West Coast Wilderness Railway are rockfall and debris flow, posing a direct threat to human life and critical railway infrastructure.

The primary objective of this research is to reduce risk and mitigate rockfall and debris flow failure hazards. To assess a range of potential risk mitigation measures using large deformation geomechanical methods, advanced numerical methods such as the Smoothed Particle Hydrodynamics (SPH) and the Coupled Eulerian Lagrangian (CEL) method will be used to model geohazard behaviour, quantify the risks to railway infrastructure and develop innovative protective rockfall and debris flow barriers. The project aims to assess the performance of protective structures such as rockfall netting, rockfall shelters, check dams and debris flow barriers and develop sustainable engineering solutions. The proposed research project will focus on large deformation numerical simulation of soil-structure and fluid-structure interactions to address and mitigate rockfall and debris-flow risks. The project will improve the understanding of rockfall and debris flow behaviour, building on current geohazard risk assessment techniques to determine best-case measures for railway infrastructure protection.
