Minimum Water Table Elevation Contours for Gnangara Jandakot 2019

2019 minimum water table elevation values for the Gnangara and Jandakot areas of Western Australia's Swan Coastal Plain. The data is discretised into 10x10 meter cells, with contours displayed at 1-meter intervals. It is provided by the Department of Water and Environmental Regulation.

Use Cases

• Model groundwater flow and recharge using the 10x10 meter cell discretisation of water table elevation values.
• Analyze spatial patterns of minimum water table elevation across the Swan Coastal Plain using the 1-meter contour intervals.
• Integrate water table elevation contours with other hydrological datasets for the Gnangara and Jandakot study areas.
• Assess land use impact on groundwater levels by correlating elevation contours with surface feature maps.

Strengths

• Data is discretised at a high spatial resolution of 10x10 meter cells.
• Contours are provided at a precise 1-meter interval for detailed elevation analysis.
• Sourced from the authoritative Department of Water and Environmental Regulation.

Limitations

• Limited to a single temporal snapshot (2019 minimum values), lacking a time series.
• Spatial coverage is restricted to the Gnangara and Jandakot areas, not the entire Swan Coastal Plain.
