Callide Creek Dam Site Seismic Refraction Survey, Queensland 1959

Queensland, Australia, hosts a 1959 seismic refraction survey for the Callide Creek 49.8-mile dam site near Biloela. The survey, conducted for the Queensland Irrigation and Water Supply Commission, determined depths to bedrock and estimated Young's modulus. After correcting a systematic 18% low bias, depth determinations were accurate to within 10 feet.

Use Cases

• Calibrating seismic velocity interpretations for bedrock depth based on comparison with drilling results mentioned in the description
• Estimating material properties like Young's modulus for unweathered bedrock based on seismic method results described
• Analyzing historical geotechnical survey accuracy and systematic error correction for dam site investigations
• Creating cross-sectional models of subsurface geology based on seismic velocities and general geological information referenced

Strengths

• Includes a quantified systematic error correction, with depth estimates noted to be about 18% too low before adjustment
• Provides a specific accuracy range after correction, stating depth determinations are accurate to within 10 feet
• Reports a calculated material property, estimating Young's modulus for bedrock at about 7 to 9 x 10,000,000 lb/in²

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Data may reflect geographic/temporal bias inherent to a single 1959 survey from data_gov_au
