ACT Potential Erosion Hazard Ratings for Hydrogeological Landscapes

Australian Capital Territory (ACT) spatial data for land management decision-making. It contains hazard ratings for land salinity, stream salt load, and stream EC, as well as overall salinity hazard for each Hydrogeological Landscape (HGL) unit. The dataset was captured at 1:25,000 scale by Rob Muller, Wayne Cook, Allan Nicholson, and Alie Cowood and last updated in April 2026.

Use Cases

• Assess land salinity hazard ratings for Hydrogeological Landscape units.
• Evaluate stream salt load and electrical conductivity (EC) hazard ratings.
• Identify appropriate salinity management strategies based on landscape functions.
• Map salinity hazard for land management decision-making at a 1:25,000 scale.

Strengths

• Contains hazard ratings for land salinity, stream salt load, and stream EC.
• Provides hyperlinks to full management descriptions for each Hydrogeological Landscape unit.
• Captured at a 1:25,000 scale, suitable for paddock-scale assessment.
• Integrates multiple information sources such as soil landscape maps, hydrogeological data, and salinity occurrence maps.

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 does not warrant that the map is free from error.
