Port Phillip-Westernport Basin Hydrogeological Inventory with Geological Formations

Geoscience Australia Data provides a hydrogeological inventory for the Port Phillip and Westernport basins in south-central Victoria. The dataset groups descriptive attributes into themes including location, geology, hydrogeology, groundwater management, and land use. It was last updated on 2026-03-25.

Use Cases

• Model groundwater flow and aquifer properties based on described hydrogeological units.
• Analyze the relationship between geological structures like faults and basin stratigraphy.
• Study land use and industry impacts on groundwater resources in the basin.
• Correlate surface water features with subsurface geology and groundwater conditions.
• Reconstruct paleoenvironments and depositional history from described sedimentary and volcanic formations.

Strengths

• Descriptive attributes are grouped into 11 specific themes, including hydrogeology and groundwater management.
• Covers two distinct sedimentary basins with detailed stratigraphy including named formations like the Yaloak and Werribee.
• Includes information on geological structures such as the Selwyn, Rowsley, and Heath Hill Faults.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided in PDF format, which may hinder direct computational analysis.
