Newcastle City Council required a comprehensive understanding of the wave climate and coastal processes affecting the historic ocean baths to ensure the redevelopment design would perform under both current and future coastal conditions.

The Newcastle Ocean Baths Revitalisation project involved the redevelopment of the historic Newcastle Ocean Baths complex. To support the design process, Tonkin + Taylor delivered specialist coastal engineering advice through detailed wave process investigations and numerical modelling. The work provided a robust technical basis for understanding wave conditions affecting the site, informing engineering design and identifying measures to improve the resilience and performance of the revitalised facility.

A key differentiator was the collection of project-specific data during a significant inundation event, allowing the numerical model to be calibrated against real-world conditions and providing increased confidence in the design recommendations.

The study delivered:
• Reliable design wave loads to inform engineering design.
• Improved understanding of current and future wave conditions.
• Evidence-based assessment of mitigation measures to enhance the resilience of the revitalised ocean baths.

Services

  • Review of historical metocean data.
  • Collection of project-specific field data during a significant inundation event to support model calibration.
  • Numerical modelling of wave processes and future scenarios.
  • Assessment of design wave loads for engineering design.
  • Investigation and evaluation of potential mitigation measures.

High value outcomes

Tonkin + Taylor combined historical metocean analysis with targeted field data collection during a major inundation event to develop a well-calibrated wave model. This enabled greater confidence in predicting site-specific wave conditions and assessing future performance of the redevelopment.

Community + environmental impacts

The redevelopment supports the preservation and continued use of one of Newcastle’s iconic public ocean baths, helping ensure the long-term resilience of a valued community recreational asset.
