Groundwater Occurrence and Aquifer Performance in the Alice Springs Town Basin

A 1957-1961 study of groundwater in the Alice Springs Town Basin, a small alluvial basin of approximately three square miles. The dataset, provided by Geoscience Australia Data, includes contour maps of the piezometric surface and discusses aquifer performance tests on specific bores. Analysis indicates a fall in the water table of between three and ten feet within the studied period.

Use Cases

• Model groundwater flow based on described aquifer constants (T = 20,000 gallons per day per foot, S = 0.05).
• Analyze water table decline using the piezometric surface maps for October 1957 and October 1961.
• Correlate groundwater occurrence with sediment lithology and depositional environments (alluvial fan, flood plains, etc.).
• Assess aquifer heterogeneity by examining inconsistent test results from bore 59/11.

Strengths

• Includes specific aquifer constants (Transmissivity T=20,000 gpd/ft, Storativity S=0.05) derived from performance tests.
• Provides temporal comparison with piezometric surface maps for two distinct years (1957 and 1961).
• Describes the geological context in detail, including basin size (three square miles) and sediment thickness (seventy-five feet).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal bias inherent to its 1957-1961 collection period.
