Seismic Refraction Survey Data for Three Barambah Creek Dam Sites, 1960

Seismic refraction surveys at three dam sites on Barambah Creek, near Murgon in Queensland, conducted at the request of the Irrigation and Water Supply Commission of Queensland. The results are plotted as cross-sections showing depth and velocity of subsurface layers, with interpretation of seismic velocities in geological terms. The data was published by Geoscience Australia and last updated in May 2026.

Use Cases

• Assessing foundation rock suitability based on interpreted seismic velocities of approximately 8000 ft/sec.
• Identifying potential fault or shear zones at dam sites based on seismic work results.
• Modeling subsurface geological layers using cross-section data showing depth and velocity.
• Planning dam design and construction based on interpreted geological conditions from the survey.

Strengths

• Data includes cross-sections showing depth and velocity for three distinct dam sites.
• Contains specific geological interpretation, identifying rocks with seismic velocities about 8000 ft/sec as moderately weathered bedrock.
• Results suggest the presence of fault or shear zones at all three surveyed sites.

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 and sample data are unknown, which may limit suitability assessment.
