Australian Coastal Aquifer Typology for Seawater Intrusion Vulnerability

Twenty-eight case study areas form the basis of a national typological framework for assessing seawater intrusion into Australian coastal aquifers. This technical report from the National Seawater Intrusion Project tabulates key hydrogeological parameters and develops conceptual models for each area. The dataset supports a vulnerability assessment by categorizing aquifers based on their climatic and hydrogeological settings.

Use Cases

• Vulnerability mapping based on tabulated aquifer parameters for 28 case study areas.
• Developing conceptual hydrogeological models using the provided cross-sectional frameworks.
• Prioritizing coastal management zones based on the aquifer typology and climatic settings.
• Calibrating regional groundwater models with the analyzed hydrogeological characteristics.

Strengths

• Provides a structured national-scale typology for 28 distinct coastal aquifer case study areas.
• Synthesizes both public and confidential information to develop conceptual models.
• Cross-platform presence on data.gov.au indicates official importance and accessibility.

Limitations

• Core dataset details like column names, row counts, and specific license are not provided in the available metadata.
• The 'last updated' dates conflict between 2026-04-04 and 2026-04 16, suggesting potential metadata inconsistency.
• The primary data format appears to be a report (PDF/DOCX/HTML), which may require extraction for quantitative analysis.
