Ivanhoe Block Hydrogeology and Salinisation Risk in the NSW Riverine Plain

A 2026 paper from the Australian Ocean Data Network describes the Ivanhoe Block, a concealed basement ridge complex affecting groundwater flow in the New South Wales part of the Western Riverine Plain. The document analyzes the structure's role as a regional groundwater divide and its impact on salinity distribution, partitioning the plain into discharge and buffer zones. It assesses the risk of land salinisation for different zones, identifying the Balranald-Hatfield area as most at risk.

Use Cases

• Model regional groundwater flow paths based on described deflection by basement ridges.
• Assess salinisation risk for land management based on the described discharge and buffer zones.
• Interpret electric log data for aquifer subdivision based on the described strata-bound salinity.
• Study the impact of geological structures on aquifer connectivity based on the described role of the Geera Clay aquitard.

Strengths

• Analysis is grounded in a specific, described geological structure (the Ivanhoe Block).
• Provides a clear spatial framework, partitioning the Western Riverine Plain into distinct hydrogeological zones.
• Addresses a contemporary environmental concern (land salinisation) with identified risk categories.

Limitations

• Data is presented in PDF/HTML formats; column-level documentation and sample data are unavailable.
• Row count and dataset scale are unknown, which may limit suitability assessment.
• The description focuses on geological interpretation; the availability of underlying raw numerical data is unclear.
