Hydrogeological Structure and Salinity Risk of the Ivanhoe Block

A geological study analyzes the Ivanhoe Block, a concealed basement ridge complex affecting groundwater flow in the New South Wales Riverine Plain. The Australian Ocean Data Network published this research, which was last updated in April 2026. It details the block's role as a regional groundwater divide and its impact on salinity distribution.

Use Cases

• Model groundwater flow deflection in deeper aquifers using data on parallel basement ridge structures.
• Assess salinity risk categories for zones like Balranald-Hatfield and Moulamein-Mossgiel based on chloride concentration change rates.
• Analyze the barrier effect of the Geera Clay aquitard and Renmark Group subdivisions on lateral groundwater throughflow.
• Map the historical extent of refluxed salt propagation in the Tertiary aquifers of the Western Riverine Plain.

Strengths

• Provides a detailed structural and hydrogeological model of a key geological feature in the Murray Basin.
• Identifies specific at-risk zones for land salinization, such as the Balranald Hatfield discharge zone.

Limitations

• Data is presented as a research paper in HTML/PDF format, not as a structured, machine-readable dataset.
• Specific quantitative data points, row counts, and column definitions are unavailable for direct computational analysis.
