Geophysical Surveys of a Dam Site on Huon River, Tasmania 1959-60

Seismic refraction and resistivity surveys determined overburden thickness and bedrock nature for a proposed dam site on the Huon River. The overburden thickness ranges from 20 to 316 feet, with an average of 70 to 80 feet across most of the area. Geoscience Australia Data collected this information for the Hydro Electric Commission of Tasmania.

Use Cases

• Estimate foundation material strength based on seismic velocity data for weathered and recemented dolerite.
• Model overburden thickness distribution for construction planning based on the 20 to 316 ft range.
• Assess bedrock composition and depth for engineering design based on seismic and drilling data.

Strengths

• Overburden thickness is quantified with a specific range of 20 to 316 feet.
• The description provides a concrete estimate of depth calculation accuracy within 30 percent.
• Survey purpose and methodology (seismic refraction, resistivity traversing) are explicitly stated.

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 1959-60; freshness should be verified for modern applications.
