Hydrogeological Inventory for Port Phillip and Westernport Basins

Two sedimentary basins in south-central Victoria contain attribute data grouped into 11 themes including location, geology, and groundwater management. The Australian Ocean Data Network compiled this inventory, with a last recorded update in April 2026. Data describes formations like the Yaloak and Werribee formations, representing millions of years of geological history.

Use Cases

• Map groundwater management zones using administrative and location attribute themes.
• Analyze relationships between surface water features and aquifer characteristics from the surface water and hydrogeology themes.
• Model stratigraphic sequences using data on formations like the Yaloak Formation, Werribee Formation, and Baxter Sandstone.
• Assess environmental impacts by correlating land use and industry data with groundwater quality metrics.
• Study basin evolution by examining fault-bounded structures like the Selwyn Fault and depositional phases described in the geology theme.

Strengths

• Data is structured into 11 distinct thematic groups for focused analysis.
• Covers two geologically significant basins with detailed stratigraphic descriptions.
• Includes information on major structural features like the Selwyn and Heath Hill Faults.

Limitations

• Specific row counts, column counts, and dataset size are unknown.
• Primary data format is PDF, which may hinder direct computational analysis.
• Temporal coverage for the observational data within the inventory is not specified.
