Maximum Depth to Groundwater Contours for Gnangara Jandakot 2019

2019 maximum depth to groundwater values for the Gnangara and Jandakot areas of the Swan Coastal Plain in Western Australia. Data is discretised into 10x10 meter cells with contours displayed at 1-meter intervals, provided by the Department of Water and Environmental Regulation.

Use Cases

• Model groundwater resource availability using the maximum depth to groundwater (DTGW) values from 2019.
• Analyze spatial patterns of water table elevation (WTE) across the 10x10 meter cell grid for the Swan Coastal Plain.
• Generate contour maps for hydrological studies using the 1-meter interval depth to groundwater data.
• Assess regional aquifer characteristics by integrating the Gnangara and Jandakot area DTGW contours.

Strengths

• Data is discretised into a consistent 10x10 meter cell grid across the study area.
• Contours are provided at a precise 1-meter interval for detailed hydrological analysis.
• Dataset is maintained by the authoritative Department of Water and Environmental Regulation.

Limitations

• Data is limited to a single temporal snapshot from 2019, lacking time-series information.
• Spatial coverage is restricted to the Gnangara and Jandakot areas, not the entire Swan Coastal Plain.
