Logan River Tidal Barrage Seismic Refraction Survey Report, Queensland 1959

Queensland's Logan River tidal barrage sites near Beenleigh were surveyed in 1959 using seismic refraction methods. The report describes the results for the 2.3M and 13.5M sites, including estimated maximum bedrock depths of 130 feet and 80 feet respectively. The data originates from a Geoscience Australia report, last updated in May 2026.

Use Cases

• Estimate bedrock depth for foundation design based on seismic refraction survey results.
• Compare subsurface conditions between potential construction sites based on the two surveyed locations.
• Validate seismic survey methodologies with follow-up test drilling as recommended in the report.

Strengths

• Provides specific bedrock depth estimates (130 ft and 80 ft) for two distinct sites.
• Includes a recommendation for test drilling to verify the seismic results, suggesting a practical validation step.
• Report is from Geoscience Australia, a government geological authority.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The primary data format is PDF/HTML, which may require extraction for computational analysis.
