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

A 1960 seismic refraction survey conducted at three dam sites on Barambah Creek near Murgon, Queensland, for the Irrigation and Water Supply Commission. The data, provided by Geoscience Australia, includes interpreted seismic velocities and cross-sections showing depth and velocity of subsurface layers. The work suggests the presence of fault or shear zones at all three proposed dam locations.

Use Cases

• Assess foundation rock suitability based on interpreted seismic velocities of approximately 8000 ft/sec.
• Identify subsurface fault or shear zones for dam site safety evaluation.
• Model subsurface geological layers using the provided depth and velocity cross-sections.

Strengths

• Includes interpreted geological data for three specific dam sites.
• Provides cross-sections showing depth and velocity of subsurface layers.
• Identifies specific seismic velocities (about 8000 ft/sec) associated with 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 in 1960; geological conditions may have changed.
