Watertable Elevation Surface: 100m Resolution Model for Victoria, Australia

Victoria, Australia's groundwater elevation surface, modeled at a 100-meter resolution in meters above the Australian Height Datum (mAHD). The dataset was produced for the Secure Allocations Future Entitlements (SAFE) project, funded under the National Groundwater Action Plan. It integrates bore readings, a digital terrain model, and existing watertable geometry models.

Use Cases

• Model groundwater flow and recharge potential based on the statewide watertable elevation surface.
• Assess groundwater resource availability for environmental planning based on the integrated bore and terrain data.
• Validate or calibrate local hydrological models using the 100m resolution regional baseline.
• Inform policy and sustainable allocation decisions for groundwater management based on the SAFE project outputs.

Strengths

• Provides a specific 100-meter spatial resolution for detailed analysis.
• Integrates multiple data sources including bore readings and a digital terrain model.
• Model output is in a standardized vertical datum (mAHD) for consistency.
• Created for a defined government-funded project (SAFE) with a clear purpose.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for certain analyses.
• The temporal coverage of the source data and the resulting model is not specified.
