Murray Basin Geology and Salinity Analysis for Southeastern Australia

The Murray Basin covers over 300,000 km² of inland southeastern Australia. This document from the Australian Ocean Data Network summarizes the basin's geology, including its structural development over 60 million years and the stratigraphy of its Cainozoic sediments, to explain subsurface factors contributing to salinity problems. The document was last updated on 2026-04-10.

Use Cases

• Model groundwater flow based on described aquifer systems and confining layers.
• Assess salinity risk factors based on the described subsurface geology and stratigraphic framework.
• Plan agricultural water management based on the basin's closed groundwater system and recharge characteristics.

Strengths

• Describes a specific geographic area covering over 300,000 km².
• Provides a temporal context for basin development spanning 60 million years.
• Details sediment thickness up to 600 meters in central-western parts.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is presented in PDF/HTML formats, which may require extraction for analysis.
