Logan River Tidal Barrage Seismic Refraction Survey Results, 1959

Queensland seismic refraction surveys at two Logan River tidal barrage sites near Beenleigh, conducted in 1959. The report describes maximum bedrock depths of 130 feet at the 2.3M site and 80 feet at the 13.5M site. It was published by the Australian Ocean Data Network and recommends test drilling to verify the seismic results.

Use Cases

• Estimate bedrock depth for foundation design based on seismic refraction survey results.
• Plan site investigation strategies based on the recommendation for test drilling.
• Compare subsurface conditions between two potential tidal barrage locations.
• Analyze historical geotechnical survey methods and reporting from the 1950s.

Strengths

• Provides specific bedrock depth estimates (130 ft and 80 ft) for two sites.
• Includes a clear recommendation for follow-up verification via test drilling.
• Report is hosted by an authoritative organization, the Australian Ocean Data Network.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data freshness should be verified; the last update date is 2026-06-04, but the survey is from 1959.
• Row count is unknown, which may limit suitability assessment.
