Research topic

This new PhD scholarship will develop advanced pore pressure analysis for groundwater systems with engineering applications in civil construction, mining operations and water supply systems. Groundwater levels, or pore pressures, go up and down in response to factors such as pumping or injection of groundwater, loads on the surface including soil moisture, and responses to small stresses in the earth from frequent earth tide and atmospheric tides.

The patterns of pore water pressure responses can reveal how aquifers and aquitards operate, how much water is stored and if there is hydraulic separation or connectivity. This requires pore pressure data logged accurately at least 8 times a day in bores at different depths, and associated gee-information. Advanced analysis of this pore pressure data can then enable real-time indicators of changing ground conditions, value adding to common groundwater monitoring:

  • Monitoring changes in soil moisture storage - important for agriculture
  • Evaluating changes in hydraulic loading - important for construction, dams and excavations

There are opportunities to better utilise groundwater data that is commonly collected to benefit engineering projects and sustainable water resource management. This research will develop advanced analytical tools to process water data in both time series and frequency domain.

The research outcomes would be new data analytical tools that are user friendly. These tools are to be user-friendly, and developed in collaboration with a group of researchers at UNSW Australia and internationally including Karlsruhe Institute of Technology (KIT) in Germany. Such tools will enable new opportunities to determine in situ properties of the ground for geomechanical and hydrogeological applications. In situ and strata specific estimates on hydraulic and para-elastic properties of the ground will be used to predict and manage loading and soil moisture.

Research project sites in regional Victoria and beyond will include one or more of the following types: groundwater supply systems for town water and agriculture, underground and open pit mine sites, civil construction and tunnelling projects, underground injection sites for recycled water/carbon sequestration, shallow geothermal energy sites.

The PhD scholar will benefit from international research collaborations and local industry partnerships, for example with government, and engineering companies.

Project aim

The research outcomes will include improved data analytics tools that are user friendly, and a paradigm shift in determining in situ properties of the ground for various engineering applications that require multi-disciplinary approaches. The PhD project will aim to:

  • Develop improved data analytical tools for pore pressure and related hydro­ geomechanical data and apply to a priority groundwater engineering project site. These tools are to be user-friendly, and developed in collaboration with a group of researchers at UNSW Australia and internationally including Karlsruhe Institute of Technology (KIT) in Germany.
  • Use these tools to measure hydraulic and para-elastic properties of the ground at selected project sites (i.e. in situ and strata specific), and to measure changes in these properties over time.
  • Develop decision support for the effectiveness of monitoring bores at detecting these properties at various scales, depending on bore depth and construction and local geology for example.
  • Analyse the sensitivity of groundwater and geomechanical models to spatial and temporal variations in hydraulic and para-elastic properties of the ground.
  • Evaluate the implications for modelled scenarios of pore pressure changes, watertable drawdown and ground movement at selected sites, in the context of sustainable water and engineering projects.
