Otway Basin Hydrogeological Inventory with Spatial Groundwater Features

150,000 square kilometres of the Otway Basin, an elongated sedimentary basin stretching 500 km from South Australia to Victoria and Tasmania, are described in this dataset. The Australian Ocean Data Network provides attribute information grouped into themes like location, geology, hydrogeology, and groundwater management. The dataset, last updated in 2026, focuses on the shallower onshore sedimentary units relevant for groundwater resources.

Use Cases

• Map groundwater management zones based on administrative boundaries and spatial groundwater features.
• Analyze the relationship between surface water features and groundwater aquifers described in the hydrogeology theme.
• Model groundwater flow influenced by the basin's intricate fault systems and structural geology.
• Assess land use and industry impacts on groundwater resources within the basin's boundaries.

Strengths

• Covers a large geographic area of approximately 150,000 square kilometres.
• Groups descriptive attributes into 11 specific thematic categories, including hydrogeology and groundwater management.
• Provides spatial context through association with a Hydrogeology Index map.

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.
