Port Fairy Coastal Hazard Lines for Seawall Failure Scenarios

Port Fairy, Victoria, Australia, is the geographic scope of this dataset. It provides hazard lines modeling shoreline setback due to coastal erosion if existing seawalls were to fail. The Department of Energy, Environment and Climate Action created this dataset, which includes projections for present day, 2050, 2080, and 2100 planning horizons.

Use Cases

• Model coastal setback for infrastructure planning based on the four hazard components (S1, S2, S3, S4)
• Visualize hazard extents for different planning horizons (present day, 2050, 2080, 2100) based on the described setback calculations
• Assess erosion risk for specific coastal features like dunes or revetments based on the use of +2m and +6m AHD contours mentioned

Strengths

• Includes specific sea level rise projections: 0.4 m for 2050, 0.8 m for 2080, and 1.2 m for 2100
• Provides hazard lines for four distinct planning horizons (present day, 2050, 2080, 2100)
• Offers data in multiple geospatial file formats (EXTENDED TAB, MIF, SHP, GDB, DXF, TAB, DWG)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Description metadata is limited; actual data quality requires manual inspection after download
