ACT Hydrogeological Landscapes with Salinity Hazard Ratings

A dataset from the ACT Government Geospatial Data Catalogue provides digital spatial data for land management in the Australian Capital Territory. It contains hazard ratings for land salinity, stream salt load, and stream EC, along with landscape function information and management strategies for each Hydrogeological Landscape unit. The data was captured at a 1:25,000 scale and was last updated in April 2026.

Use Cases

• Assessing paddock-scale salinity hazard based on hazard ratings for land salinity, stream salt load, and stream EC.
• Planning land management strategies using the listed landscape functions and appropriate salinity management strategies.
• Understanding regional salt stores and pathways by analyzing the delineated Hydrogeological Landscape units.
• Integrating causative factors like geology, soils, slope, regolith thickness, and climate for salinity modeling.

Strengths

• Contains hazard ratings for land salinity, stream salt load, and stream EC for each Hydrogeological Landscape unit.
• Data was captured at a 1:25,000 scale, suitable for paddock-scale assessment.
• Includes hyperlinks to full management descriptions for each HGL unit.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The ACT Government disclaimer states the map may not be free from error.
