Barambah Creek Dam Sites: Seismic Refraction Survey Data from 1960

Seismic refraction surveys at three dam sites on Barambah Creek, near Murgon in Queensland, conducted in 1960. The work was performed at the request of the Irrigation and Water Supply Commission of Queensland, with results interpreted by Geoscience Australia. The data includes cross-sections showing depth and velocity of subsurface layers, with special attention to rocks with seismic velocities around 8000 ft/sec.

Use Cases

• Assessing foundation rock suitability based on interpreted seismic velocities of around 8000 ft/sec.
• Identifying potential fault or shear zones at dam sites as suggested by the seismic work.
• Planning dam design by analyzing cross-sectional data showing depth and velocity of subsurface layers.
• Conducting geological interpretation of seismic velocity data for a specific site.

Strengths

• Data is specific to three distinct dam sites (977M, 1173M, 1250M) on Barambah Creek.
• Includes interpreted cross-sections showing depth and velocity of subsurface layers.
• Provides specific seismic velocity thresholds (about 8000 ft/sec) for identifying moderately weathered bedrock.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a single survey year (1960); geological conditions may have changed.
