The Groundwater Systems Research (GSR) program provides:
- a focus for groundwater research
- multidisciplinary expertise and applications
- opportunities for joint studies and collaboration.
GSR was established to provide a focus for groundwater-related research both within QUT and externally via collaboration with government, industry and private sectors. Important outcomes of the program are multidisciplinary projects based on genuine integration.
GSR supports joint studies and collaboration between researchers in the geosciences, hydrology, hydrogeochemistry, IT and computing (high-performance computing), mathematical sciences and environmental engineering.

Australia is a dry country and has a population concentrated in coastal zones. This puts much of the nation's highly variable water supply at risk of becoming over-exploited or degraded.
Many of the water resources are already stressed due to excessive use, drought, climate impacts and the demands of supporting rapidly growing population centres. The recent drought from 1998 to 2009 resulted in very low dam levels, an awareness of the limitations on water resources, and a greater appreciation of groundwater, its finite nature, and the need to manage it. This was notably the case in South East Queensland.
Irrigated catchments in particular require groundwater system understanding to support effective management, which includes knowledge of processes such as recharge, stream flow, links to stream and geological formations. Monitoring of water levels and quality and measurement of use are highly important.
Approach to essential groundwater management
To help meet future water needs, QUT is investigating how these impacts are affecting the hydrological cycle, surface and groundwater resources, environmental flows and freshwater biodiversity.
The interaction of water resources, natural environmental systems and the geological framework must be well understood. Studies at a wide range of scales are needed, from the very local to regional basin-wide. Applications are directed to water resource supply, environmental conditions and coastal settings, as well as groundwater systems related to basin resources.
The link between groundwater and resources is of fundamental importance to sustainable utilisation of resources within sedimentary basins, such as coal seam gas (CSG), shale gas and coal deposits. The considerations are for both the surface environment and the condition of associated groundwater aquifers.
Groundwater basins of Queensland
The Surat Basin is a sub-basin of the Great Artesian Basin. One project has been to develop a regional basin model for Arrow Energy. This is an integrated geological/conceptual hydrogeological model in 3D incorporating solid geometry, all drillholes, plus groundwater piezometric surfaces. The model domain extends 450km NW-SE and 270km NE-SW, and includes much of the Condamine alluvium.
Walloon Coal Measures
This formation (WCM) is the main target for coal seam gas (CSG) in the Surat Basin. It consists of six recognised interbedded units of coal and sandstone. Units are of variable thickness and permeability, and all contain some groundwater, mostly poor quality. The total sequence can be 200-300m thick.
Galilee and Eromanga Basins
A project funded by Exoma Energy is developing a sub-regional basin model for the Galilee Basin and the overlying Eromanga Basin, which is part of the Great Artesian Basin (GAB) and contains important artesian aquifers. The model domain is centred around Longreach in Western Queensland and is 300 km W-E and 275 km N-S. The 3D visualisation model (GVS) will incorporate all available data as well as new company-generated information.
The Clarence-Moreton Basin (CMB) to the east is connected to the Surat Basin. Significant surface water catchments overlying the CMB include:
- Condamine Valley
- Lockyer Valley
- Bremer Valley
- Teviot Brook Catchment.
The CMB extends from South East Queensland into New South Wales, and underlies the Richmond and Clarence River catchments.
Hydrogeologically, the CMB hosts a variety of different aquifer types (alluvial, volcanic and sedimentary aquifers), which are connected to varying degrees.
Regional groundwater research on the CMB was part of a QUT Postdoctoral Fellowship by Dr Matthias Raiber, funded by National Centre for Groundwater Research and Training (NCGRT), and now continuing with CSIRO. The project developed a basin-wide 3D geological model, incorporating hydrogeological, hydrogeochemical and isotopic data.
Particular aspects of these projects include:
- development of 3D geological models (GoCAD)
- assessment of flood-related recharge to alluvial aquifers in the Lockyer Valley and Condamine Catchment using 3D visualisation and environmental tracers
- groundwater chemistry baseline study using multivariate statistical analysis of water chemistry data (from DNRM database)
- study of interactions between GAB, volcanic and alluvial aquifers using water chemistry, hydrogeological data and environmental tracers (stable isotopes, 87Sr/86Sr, 3H and radiocarbon)
- integration of all data to form a basin-wide 3D hydrogeological conceptual model.
The 3D approach is capable of integrating multiple types of information (topography, geological, hydraulic, water chemistry and spatial) into a single representation, which provides valuable insights into the major factors controlling aquifer processes.

Groundwater Visualisation System software
Groundwater Visualisation System (GVS) is a versatile software package that can produce 3D visualisation of geological and hydrological systems.
The 3D framework enables development of conceptual hydrogeological models. This format allows identification of temporal groundwater and surface water processes, and the time-space relationships. The ability to animate time-series data, interrogate and interact with the 3D model enables a greater understanding of the components, infrastructure and functions of groundwater systems.
GVS is a flexible and user-friendly groundwater management tool, developed by QUT and based on open-source software which can be readily redistributed.
GVS models are customised for specific project requirements. The models developed integrate a wide range of spatial and time-series data from both surface and subsurface settings.
QUT is currently collaborating with the University of Ballarat in Victoria to combine this 3D capability within their online system VVG (Visualising Victoria's Groundwater).
