Groundwater Occurrence and Aquifer Performance in the Alice Springs Town Basin, 1957-1961

Geoscience Australia Data provides a report on groundwater in the Alice Springs Town Basin, a small alluvial basin of approximately three square miles. The dataset includes contour maps of the piezometric surface for October 1957 and October 1961, showing a water level decline of between three and ten feet. Aquifer performance tests on specific bores provided values for transmissivity (T = 20,000 gallons per day per foot) and storativity (S = 0.05).

Use Cases

• Modeling groundwater flow based on described aquifer constants (T and S values).
• Analyzing historical water level decline based on piezometric surface maps from 1957 and 1961.
• Correlating groundwater occurrence with sediment lithology and depositional environments mentioned in the description.
• Assessing aquifer heterogeneity based on inconsistent test results from bore 59/11.

Strengths

• Includes specific aquifer performance constants: transmissivity (T) of 20,000 gallons per day per foot and storativity (S) of 0.05.
• Provides temporal comparison with piezometric surface maps for two specific years (October 1957 and October 1961).
• Describes a quantified water level decline of between three and ten feet over a four-year period.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is contained in PDF/HTML reports, which may require extraction for computational analysis.
