Geoscience Australia's Exploring for the Future Program presents the second iteration of 3D geological and hydrogeological surfaces across eastern Australian basins. The work updates surface extents and thicknesses for 18 region-wide hydrogeological units, incorporating new borehole data and extending coverage from the Gulf of Carpentaria to the Bight, Otway, and Gippsland basins. It aims to provide a consistent hydrogeological framework for sustainable groundwater resource management.
Use Cases
- Model groundwater flow and storage based on updated 3D hydrogeological surfaces.
- Assess regional aquifer thickness and extent for resource planning.
- Integrate geological data across basin borders for national-scale assessments.
- Reconcile legacy and contemporary stratigraphic studies under a common framework.
Strengths
- Updates 18 region-wide hydrogeological units.
- Incorporates new borehole data including petroleum, CSG, stratigraphic, mineral, and water boreholes.
- Study area extends across multiple basins from the Gulf of Carpentaria to southern offshore basins.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
