MSc in Parameter estimation using Bayesian techniques to reduce uncertainty in process-based modelling of permafrost soil carbon

This project seeks to understand the strength and thaw consolidation characteristics of permafrost sediments through a comprehensive laboratory program. Starting with existing laboratory data, both published and from industry where available, we will build a geotechnical permafrost soils database in collaboration with the other projects in the network. The specific data gaps, the quality and reliability of the data will inform the direction of the experimental pro- gram, adding to previous databases that have compiled mostly geotechnical index properties.

PhD in geomechanical properties of thawing permafrost

This program will investigate a number of interrelated conditions that govern overall settlement of de-grading permafrost such as strength, consolidation behaviour and excess pore pressure dissipation. We aim to develop simple constitutive relations that describe the major geomechanical properties based on measurable and available parameters including soil type and ice content. Using the experimental data from the network, a synthesized model, which predicts frozen strength and thaw consolidation for soil type, temperature and ice content will be developed.

PhD in risk management of linear infrastructure in remote permafrost terrain

The Churchill Railway, which has experienced damage and failures due to flooding and permafrost thaw events, will provide the basis for a strategic case study. The PhD candidate will collect, synthesize and integrate a range of datasets (e.g. topographic, meteorological, hydrological, geotechnical, geophysical), which may be acquired through desktop studies, field investigations (e.g. electrical resistivity tomography field survey, boreholes) and remote sensing (e.g. satellite, drone) observations. Empirical and screening level computational tools will be advanced to generate risk estimates along the Infrastructure right of way. This improved knowledge base and tools will help to identify regions of interest where more detailed and localized investigations or assessments are required to refine the risk estimate. This will support owners in more effective decision making under uncertainty, within an evidence based risk framework, for the asset management of linear infrastructure in permafrost environments.

PhD in quantifying the ice and water content of permafrost with dielectric methods

This project will improve methods for measuring and monitoring ground-ice content and permafrost thaw directly. This is important because changing soil characteristics govern the impacts of permafrost thaw on the natural and built environment, but permafrost temperature alone reveals these changes only incompletely. This project will advance (a) the understanding of soil thaw close to 0ºC, (b) in situ measurement of liquid water content in permafrost for tracking thaw, and (c) the geophysical detection of ground ice.
