Otway Basin Hydrogeological Features and Attributes

An inventory of hydrogeological features for the Otway Basin, a sedimentary basin covering approximately 150,000 square kilometres along Australia's south-east margin. The dataset groups descriptive attributes into themes including location, geology, hydrogeology, groundwater, and land use. It is provided by the Australian Ocean Data Network and was last updated in April 2026.

Use Cases

• Analyze relationships between geological features like fault systems and groundwater flow conduits using structural geology attributes.
• Map groundwater-bearing aquifers by correlating late Cretaceous and Cenozoic sedimentary rock data with hydrogeology themes.
• Assess land use and industry types in relation to groundwater management and use data for regional planning.
• Study the influence of surface water features and physical geography on groundwater resources within the basin's spatial boundaries.

Strengths

• Covers a large spatial area of approximately 150,000 square kilometres.
• Groups data into 11 distinct thematic categories for structured analysis.
• Includes information on complex geological evolution and structural features influencing groundwater.

Limitations

• Specific row counts, column details, and sample data are unavailable.
• The primary file format is PDF, which is not ideal for computational analysis.
• The dataset's focus is largely descriptive, with unknown quantitative measurement granularity.
