About the research project
Heavy rainfall and a changing climate have a direct correlation with the frequency of large geohazard events. Rainfall is a crucial factor in developing debris flow risk mitigation strategies in a Tasmanian context. Current methods to assess the magnitude of catastrophic debris flows and landslides often account for a variety of possible precipitation events, incorporating inherent variability, uncertainty and spatial variability for rainfall and run-off. Although uncertainty, heterogeneity and spatial dependencies are commonplace in assessing rainfall for debris flow risk, large-scale probabilistic methods have yet to incorporate the variability of geotechnical and hydrological factors.
Numerical simulations have shown that the destructive potential debris flows are particularly sensitive to initial conditions, including debris flow orientation and position, channel geometry, surface roughness and sedimentary concentrations. This research aims to quantify the effects of debris flow uncertainties on the performance protective structures such as check dams, rigid barriers and flexible nets. The project will develop probabilistic methods for Monte Carlo simulation of debris flow run-out behaviour, as well as debris flow barrier performance, incorporating probabilistic assessment tools as part of random field theory, coupled with large deformation numerical simulation. The creation of innovative probabilistic models will drive sustainable engineering solutions for risk mitigation, accommodating for debris flow uncertainty, heterogeneity and spatial variability.
Applicants will be considered for a Research Training Program (RTP) scholarship or Tasmania Graduate Research Scholarship (TGRS) which, if successful, provides:
- a living allowance stipend of $28,597 per annum (2021 rate, indexed annually) for 3.5 years
- a relocation allowance of up to $2,000
- a tuition fees offset covering the cost of tuition fees for up to four years (domestic applicants only)
If successful, international applicants will receive a University of Tasmania Fees Offset for up to four years.
As part of the application process you may indicate if you do not wish to be considered for scholarship funding.
The project is open to domestic (Australian and New Zealand) and international applicants who are already in Australia (onshore) at the time of submitting their application.
Due to current Australian COVID-19 travel restrictions the University cannot accept applications from international applicants who are currently overseas.
