Western Australia Coastal Tertiary Compartments For Coastal Management

Western Australia coastal compartments provide a geological and landform-based framework for coastal planning. The dataset structures the coastline into primary, secondary, and tertiary compartments based on rock type, shoreline orientation, and landform associations. It was commissioned by the Department of Planning and compiled by Damara Pty Ltd and the Geological Society of WA, with a supporting report published in August 2011.

Use Cases

• Map and analyze coastal change and drift patterns using the compartment boundaries for shoreline management.
• Plan marine development and ecosystem protection by integrating compartment data with landform associations.
• Model sand transport and dune blowout risks within defined tertiary compartments for coastal protection strategies.

Strengths

• Based on a commissioned study and compiled by professional geological consultants.
• Integrated into a nationwide compartment dataset developed by Geoscience Australia.
• Includes tags for key coastal features like Beachface, Littoral, Dune, and Ecosystem.

Limitations

• Attribution for the dataset is described as incomplete and ongoing.
• Some superficial changes have been made since the original 2011 report, potentially creating version discrepancies.
• Available only via WMS and ArcGIS Server map service, limiting direct tabular analysis.
