Victorian Aquifer Framework: Salinity Distribution for the Upper Tertiary Aquifer

Victorian Aquifer Framework (VAF) Salinity Distribution dataset maps salinity for Aquifer Number 105, the Upper Tertiary Aquifer (Fluvial). The salinity distributions reflect beneficial use segments prescribed in the State Environment Protection Policy (Waters) from 2018. The dataset is provided by the Department of Energy, Environment and Climate Action and was last updated in April 2026.

Use Cases

• Model groundwater salinity distribution based on aquifer segmentation.
• Assess compliance with environmental water policy based on beneficial use segments.
• Map hydrogeological features for the Upper Tertiary Aquifer (Fluvial) based on spatial data.
• Analyze spatial relationships between aquifer properties and regulatory frameworks.

Strengths

• Data is explicitly linked to the 2018 State Environment Protection Policy (Waters), providing a regulatory context.
• Available in multiple geospatial file formats (DWG, GDB, SHP, MIF, DXF, EXTENDED TAB, TAB) for interoperability.
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
