In response to growing climate-related threats, the Heraklion Port Authority (HPA), in collaboration with the European Investment Bank (EIB), launched a Climate Risk and Vulnerability Assessment (CRVA) to evaluate and address the port’s exposure to climate change. Conducted by ROGAN Associates and the University of Patras, the study applies advanced modeling tools and scenario-based analysis to inform strategic planning and long-term adaptation.
The project’s objective was to identify the most significant hazards – including sea level rise, extreme rainfall, sediment transport, and wave overtopping – and to assess their potential impact on critical port infrastructure and operations. Utilizing climate projections under RCP4.5 and RCP8.5 scenarios, the study anticipates sea level rise of up to 0.85 meters by 2100 and increased drainage system failure during extreme weather events. Key technical characteristics and achievements include:
- Integrated hydrodynamic modeling of waves and sediment flows;
- Flood risk mapping and critical asset exposure analysis;
- An actionable set of engineering and operational adaptation measures;
- Development of a monitoring and early warning plan;
- Alignment of adaptation pathways with SDGs and international port sustainability frameworks.
The CRVA report, released in February 2024, identifies sea level rise, extreme precipitation, and sediment transport as key risks, and proposes engineering and operational adaptation measures. The proposed adaptation measures include; upgrading quay wall elevations and reinforcing breakwaters, improving the port’s stormwater drainage infrastructure, installing real-time monitoring and alert systems, and incorporating climate adaptation in future infrastructure planning.
The CRVA aligns with IAPH evaluation criteria as follows:
- Innovation: Combines scientific rigor with practical infrastructure foresight;
- Leadership: Demonstrates proactive climate resilience planning for a medium-sized Mediterranean port;
- Impact and Transferability: Offers a robust methodology applicable to similar ports worldwide;
- Sustainability: Directly supports SDG 13 (Climate Action), SDG 9 (Resilient Infrastructure), and SDG 11 (Sustainable Communities).
This project establishes Heraklion Port as a forward-looking and climate-resilient gateway in the Eastern Mediterranean.
