Otway Basin Hydrogeological Inventory with 11 Thematic Groups

The Otway Basin hydrogeological inventory is a dataset from the Australian Ocean Data Network, last updated in April 2026. It contains descriptive attribute information for spatial groundwater features, grouped into 11 themes including location, geology, hydrogeology, and land use. The dataset covers the Otway Basin, an elongated sedimentary basin of approximately 150,000 square kilometres on Australia's south-east continental margin.

Use Cases

• Analyze groundwater management and use patterns based on the administrative and industry themes.
• Study the relationship between complex structural geology and groundwater flow based on the geology and hydrogeology themes.
• Model sedimentary aquifer systems based on descriptions of late Cretaceous and Cenozoic rock formations.
• Assess environmental and land use impacts on groundwater resources based on the environment and land use themes.

Strengths

• Covers a large geographic area of approximately 150,000 square kilometres.
• Organizes information into 11 distinct thematic groups for structured analysis.
• Describes a basin with a complex geological history shaped by rifting, subsidence, and volcanic activity.

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.
