Australian Coastal Aquifer Typology For Seawater Intrusion Vulnerability

A typological framework categorizes 28 coastal aquifer case study areas across Australia to assess vulnerability to seawater intrusion. The Australian Ocean Data Network developed this assessment using public and confidential hydrogeological data. The technical report was last updated in April 2026.

Use Cases

• Classify aquifer vulnerability using the developed typological framework and tabulated hydrogeological parameters.
• Model seawater intrusion risks by applying conceptual cross-sectional models from the 28 case study areas.
• Analyze correlations between aquifer characteristics like hydrogeological settings and climatic conditions.
• Benchmark local aquifer data against the national-scale tabulated parameters for comparative assessment.

Strengths

• Analysis covers 28 distinct coastal case study areas across Australia.
• Integrates both public and confidential data sources for parameter tabulation.
• Provides a structured typological framework for systematic aquifer categorization.

Limitations

• Sample size is limited to 28 case studies, which may not represent all coastal aquifer types.
• Underlying confidential data may restrict full reproducibility or public verification.
• The primary data format is report-based (DOCX, HTML, PDF), requiring extraction for computational use.
