Murray-Darling Basin Floodplain Environmental Water Management Areas

Murray-Darling Basin Authority data delineates floodplain areas managed with environmental water. The dataset classifies zones as actively or passively managed for receiving 2750 gigalitres of environmental water. It includes areas potentially inundated if key constraints are overcome.

Use Cases

• Map actively managed areas receiving water via headwater storages or environmental works sites for infrastructure planning.
• Analyze passively managed areas influenced by flow rules in water resource plans for hydrological modeling.
• Identify potential inundation zones contingent on overcoming key constraints for flood risk assessment.
• Integrate floodplain classification with other spatial data using GEOJSON or SHP formats for basin-wide environmental studies.

Strengths

• Authoritative source from the Murray-Darling Basin Authority, the governing body for the basin.
• Includes classification of three distinct management types: active, passive, and constraint-dependent.
• Available in multiple spatial formats (GEOJSON, SHP, WMS, WFS) for interoperability.

Limitations

• No quantitative attributes (rows, columns, size) are provided to assess dataset scale.
• Spatial resolution and precision of the polygon boundaries are not described.
• Relies on descriptive management categories without accompanying time-series or volumetric data.
