Callide Creek Dam Site Seismic Refraction Survey, Queensland 1959

A 1959 seismic refraction survey determined depths to bedrock at the Callide Creek dam site in Queensland. The survey, conducted for the Queensland Irrigation and Water Supply Commission, includes cross-sections showing rock layers identified by seismic velocity. After correcting a systematic 18% underestimation, depth determinations were accurate to within 10 feet.

Use Cases

• Calibrate seismic velocity models for bedrock depth based on the described systematic error correction.
• Estimate Young's modulus for unweathered bedrock using the provided seismic method results.
• Validate modern geophysical survey methods by comparing results with this historical dataset.
• Assess subsurface geology for dam foundation stability based on the cross-sectional data.

Strengths

• Depth determinations were accurate to within 10 feet after correcting a systematic error.
• Young's modulus for unweathered bedrock is estimated at about 7 to 9 x 10,000,000 lb/in2.
• Results were compared with drilling data to validate the seismic method.

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.
• Row count is unknown, which may limit suitability assessment.
