Shoreline Response to Clustered Storms in Southeast Australia Case Studies

Southeast Australia case studies from Adelaide and Old Bar beaches model shoreline erosion from clustered storm events. The framework integrates coastal geomorphology and engineering, using sediment compartment mapping and sub-surface data like boreholes and ground-penetrating radar. This work is a contribution to the Bushfire and Natural Hazard Cooperative Research Centre project on storm surge resilience.

Use Cases

• Modeling site-specific shoreline erosion based on sediment volume estimates in the upper beach to foredune.
• Analyzing coastal vulnerability to clustered storm events based on an observed and hindcast event time series.
• Informing coastal management strategies based on the coastal sediment compartment as a functional management unit.
• Assessing at-risk infrastructure based on the integrated geomorphological and engineering framework.

Strengths

• Focuses on two specific case study areas with management priority: Adelaide metropolitan coast and Old Bar beach.
• Integrates multiple data sources, including boreholes and ground-penetrating radar profiles for sub-surface information.
• Framework is designed to directly inform management agencies at a relevant spatial scale.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the two specific case study sites in southeast Australia.
