Hydrological Zones for Dryland Salinity Reporting in Western Australia

Hydrological zones delineate areas of similar hydrology in Western Australia, derived from soil-landscape mapping Version 5.01. The zones are used by the Department of Primary Industries and Regional Development to report on dryland salinity and acidification of inland waterways.

Use Cases

• Analyze spatial patterns of dryland salinity risk across hydrological zone boundaries.
• Model acidification trends in inland waterways using the hydrological zone spatial framework.
• Integrate zone boundaries with soil-landscape attributes for regional environmental reporting.

Strengths

• Derived from authoritative soil-landscape mapping Version 5.01.
• Maintained by the Department of Primary Industries and Regional Development.
• Updated as recently as March 2026.

Limitations

• No quantitative data on salinity or acidification levels is provided within the dataset.
• Spatial coverage is limited to the agricultural areas of south-west Western Australia.
• Specific metadata on zone count, area, or attribute columns is unavailable.
