PROJECT
Effect of faults and barriers on groundwater flow and solute transport
Understanding the nature and role of hydraulic barriers in groundwater systems
This project will address the role of faults and dykes on groundwater flow and solute transport. Faults and dykes can act as barriers to groundwater flow, yet faults can also be conduits for flow through otherwise impermeable layers. Understanding their role is critical to assessing the impacts of mining, unconventional gas and water resource developments.
This project expects to develop new methods to quantify groundwater flow through and along faults and dykes by combining geological, hydraulic and geochemical approaches with detailed 3D numerical models. The expected outcome will be an improved understanding of the role of faults and barriers in subsurface hydrology, and an improved ability to model complex groundwater systems.
For more background information, see the suggested readings below.
As part of this project the successful PhD applicant will:
- Interpret hydraulic response data and results of geophysical investigations to identify potential fault structures in the Perth metropolitan area.
- Hypothetical and real-world groundwater flow and reactive transport modelling to identify fault characteristics that are consistent with observed data. Data worth techniques will also be used to reduce uncertainty in these characteristics through new sampling campaigns.
- Conduct fieldwork in the Perth metropolitan area to obtain environmental tracer and other water chemistry data relevant to along fault flow.

Research team leader: Dr Adam Siade
I am a Hydrogeologist with broad research interests including, groundwater hydrology, contaminant transport, uncertainty assessment, data worth and design, and environmental decision support. I’m particularly interested in developing techniques to improve our understanding of natural systems such that the risks of adverse anthropogenic impacts on these systems are minimised.
