Murray-Darling Basin Floodplain Inundation From Environmental Water

2014-2021 data maps areas of Australia's Murray-Darling Basin inundated by Commonwealth environmental water. It combines the Murray-Darling Basin Authority's managed floodplain spatial dataset with polygons identified through the Long Term Intervention Monitoring and Flow-MER programs. The dataset was created by the Flow-MER program for the Commonwealth Environmental Water Holder.

Use Cases

• Analyze spatial overlap between actively_managed_areas and polygons of Commonwealth environmental water inundation.
• Map the extent of passively_managed_areas that receive water via flow rules or natural events.
• Assess potential inundation areas if key_constraints are overcome using the geospatial polygon data.
• Track changes in floodplain watering from environmental water between 2014 and 2021.

Strengths

• Covers a 7-year time range from 2014 to 2021.
• Integrates data from two major monitoring programs: LTIM (2014-2019) and Flow-MER.

Limitations

• Specific row counts and dataset size are unknown.
• Data is limited to areas influenced by Commonwealth environmental water, not all floodplain inundation.
