Victorian Aquifer Framework (VAF) Salinity Distribution - UTB_TDS

Victorian Aquifer Framework (VAF) Salinity Distribution dataset maps salinity for Aquifer Number 101, the Upper Tertiary/Quaternary Basalt Aquifer. The salinity distributions reflect beneficial use segments prescribed in the State Environment Protection Policy (Waters) (2018). The dataset is provided by the Department of Energy, Environment and Climate Action and was last updated on 2026-04 09.

Use Cases

• Model groundwater salinity contamination based on aquifer boundaries.
• Assess regulatory compliance for water beneficial use segments.
• Map spatial distribution of salinity within the Upper Tertiary/Quaternary Basalt Aquifer.
• Analyze hydrogeological characteristics of specific Victorian aquifers.

Strengths

• Data is tied to a specific regulatory framework (State Environment Protection Policy (Waters) 2018).
• Covers a defined aquifer unit (Aquifer Number 101).
• Available in multiple geospatial file formats (DWG, GDB, SHP, MIF, DXF, EXTENDED TAB, TAB).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, focusing solely on Victoria, Australia.
