ACT Salinity Hazard Ratings for Hydrogeological Landscape Units

Hydrogeological Landscape (HGL) units differentiate areas with similar salt stores and pathways across the Australian Capital Territory. The dataset contains hazard ratings for land salinity, stream salt load, and stream EC, along with management strategies and hyperlinks to full descriptions. It was captured at a 1:25,000 scale by Rob Muller, Wayne Cook, Allan Nicholson, and Alie Cowood for paddock-scale land management assessment.

Use Cases

• Assess land salinity hazard ratings for specific Hydrogeological Landscape (HGL) units.
• Evaluate stream salt load and electrical conductivity (EC) hazards for water quality management.
• Identify appropriate salinity management strategies based on landscape function descriptions.
• Integrate causative factors like geology, soils, slope, and climate for regional salinity modeling.

Strengths

• Data is fit for purpose at a 1:25,000 scale for paddock-scale assessment.
• Includes hyperlinks to full management descriptions for each HGL unit.
• Integrates multiple information sources such as soil landscape maps, site characterisation, and hydrogeological data.

Limitations

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