Murray-Darling Basin Valley Boundaries For Environmental Water Monitoring

Valley boundaries for the Murray-Darling Basin support the Commonwealth Environmental Water Holder's monitoring and research. The dataset is modified from the Sustainable Rivers Audit valleys to align with water accounting and the Long Term Intervention Monitoring project. It was published by the Flow-MER program in 2023.

Use Cases

• Delineate water accounting units for the Basin Plan 2012 using the provided valley boundary polygons.
• Partition Selected Areas for the Long Term Intervention Monitoring project based on the modified Sustainable Rivers Audit valley data.
• Analyze the contribution of Commonwealth environmental water to ecological objectives by linking these boundaries with hydrological and ecological monitoring data.
• Support spatial analysis for the Flow-MER program's reporting on environmental outcomes from managed water flows.

Strengths

• Spatial dataset provided in multiple standard GIS formats including GEOJSON and SHP.
• Data is officially sourced from the Commonwealth Environmental Water Holder, an authoritative government agency.
• Includes formal citation and acknowledgment protocols for reproducible use.

Limitations

• No metadata on the spatial resolution, precision, or scale of the boundary polygons is provided.
• Dataset size and row/feature counts are unspecified, complicating project planning.
• The underlying data modification process from the Sustainable Rivers Audit is not detailed.
