Minimum Depth to Groundwater Raster for Gnangara and Jandakot 2019

10x10m raster cells contain minimum depth to groundwater values for 2019 across the Gnangara and Jandakot areas of Western Australia's Swan Coastal Plain. The dataset, created by the Department of Water and Environmental Regulation, displays contours at 1-meter intervals.

Use Cases

• Model groundwater resource availability using the 10x10m cell discretization of depth to groundwater values.
• Analyze spatial patterns of minimum water table elevation across the Swan Coastal Plain study area.
• Integrate depth to groundwater contours displayed at 1m intervals with other hydrological datasets for regional water management.

Strengths

• Data is discretized into a fine 10x10 meter grid resolution for detailed spatial analysis.
• Contours are provided at precise 1-meter intervals for clear interpretation of groundwater depth gradients.
• Dataset is authored by the authoritative Department of Water and Environmental Regulation for Western Australia.

Limitations

• Data is limited to a single year (2019), providing only a snapshot and not a temporal trend.
• The dataset covers only two specific areas (Gnangara and Jandakot) within the broader Swan Coastal Plain region.
