Murray-Darling Basin Managed Floodplain Inundation Areas

2014-2021 data maps areas inundated by Commonwealth environmental water in Australia's Murray-Darling Basin. It extends the MDBA's managed floodplain dataset with polygons from the Flow-MER and LTIM monitoring programs. The dataset was created by the Commonwealth Environmental Water Holder's Flow-MER program and published in 2022.

Use Cases

• Analyze the spatial extent of actively managed areas receiving water via headwater storages or environmental works sites.
• Map passively managed areas inundated by flow rules in water resource plans or natural events using polygon data.
• Identify potential inundation areas for high flows if key constraints are overcome using the geospatial features.
• Evaluate the contribution of Commonwealth environmental water to Basin Plan objectives by comparing inundation polygons from 2014-2021.

Strengths

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

Limitations

• Specific row count and spatial resolution of polygons are unknown.
• Data is limited to areas influenced by Commonwealth environmental water, not all floodplain inundation.
