Australia's River Basins 1997: National Hydrological Boundaries

245 drainage basins, 77 water regions, and 12 drainage divisions across Australia, defined by the Australian Water Resources Management Committee. Australia's River Basins 1997 resulted from a joint State, Territory, and Commonwealth Government project to create a national spatial database of major hydrological basins. The metadata was prepared for the eAtlas and is not authoritative; the custodian should be contacted for an authoritative record.

Use Cases

• Map national water resource boundaries based on the hierarchical division of drainage divisions, regions, and basins.
• Analyze hydrological connectivity for environmental impact assessments based on the defined river basin boundaries.
• Support regional water policy and planning based on the standardized spatial database created by a government project.

Strengths

• Contains a defined hierarchy of 12 drainage divisions, 77 water regions, and 245 river basins.
• Created through a joint government project, suggesting a standardized national approach.

Limitations

• Metadata is explicitly noted as not authoritative; the custodian must be contacted for an authoritative record.
• Column-level documentation is absent; field semantics must be inferred after download.
