Groundwater Resource Unit Boundaries in Murray-Darling Basin

80 groundwater SDL resource units define water extraction boundaries in the Murray-Darling Basin. The dataset includes 11 deep groundwater units and accounts for overlapping aquifers, differentiated by fields like GWSDLName and GWSDLType. It was published by the Murray-Darling Basin Authority and updated in March 2026.

Use Cases

• Map and analyze the spatial boundaries of the 80 groundwater SDL resource units for regional water planning.
• Differentiate overlapping aquifers using the GWSDLName field and its suffix identifiers (a, b, c).
• Identify and separate surface groundwater from deep groundwater resource units using the GWSDLType field.
• Assess areas of overlap between groundwater and deep groundwater SDL units for integrated resource management.

Strengths

• Defines 80 distinct groundwater SDL resource units for regulatory clarity.
• Includes 11 specific deep groundwater units, providing subsurface hydrological detail.
• Explicitly documents overlapping units and provides fields (GWSDLName, GWSDLType) for differentiation.
• Published and maintained by the authoritative Murray-Darling Basin Authority.

Limitations

• No row or column count provided, limiting understanding of dataset scale and structure.
• Sample data unavailable, preventing preview of attribute values and schema.
• Relies on descriptive documentation; the absence of tabular column details may complicate quantitative analysis.
