Members of the EcoC2S project participated in the 42nd International School of Hydraulics, held on 20-23 May 2025 in Radocza, Poland. Dr. Michael Nones from the Institute of Geophysics, Polish Academy of Science, gave a brief presentation of EcoC2S project aims and current activities. The presentation highlighted the project’s focus on adaptation strategies to reduce flood risk through improved ecosystem services assessments. During the event, EcoC2S team members also engaged with researchers and practitioners from across Europe, discussing potential collaborations and knowledge exchange opportunities related to EcoC2S project topics.
Prof. Miguel Ortega and Dr. María Bermúdez from University of Granada participated in the official kick-off meeting for projects funded under the 2023 Joint Transnational Call, held in Montpellier, France, on 9-10 April 2025.
Dr. María Bermúdez, coordinator of the EcoC2S project, presented the project’s aims, methodologies, and expected impacts. Together with Jing Li (Lund University), Prof. Miguel Ortega, as scientific coordinators, led the Knowledge Hub session on Aquatic Ecosystem Services, facilitating discussions on knowledge sharing and alignment among participating projects.
The meeting provided a valuable opportunity to connect with other projects, explore synergies, and receive guidance from the Water4All follow-up team to maximize project impacts.
Members of the EcoC2S team at the University of Granada (UGR), together with researchers of the Universitat Politècnica de Catalunya (UPC), have developed a method to detect and classify areas at high risk of compound flooding—flooding caused by the combined effects of heavy rainfall, river overflow, and coastal events such as storms and waves.
While the EU Floods Directive provides a common framework for flood risk management, current assessments often focus on single-source events, overlooking the combined risks of compound flooding. The new method efficiently identifies Areas of Potential Significant Flood Risk (APSFR) by considering the intensity, likelihood, and interactions of multiple hazards. Analyzing 1,600 km of the Spanish Mediterranean coastline, the study identified three particularly vulnerable regions: central Valencia, northern Catalonia, and western Andalusia. Of the 214 APSFRs assessed, 11% fall into the highest risk category.

This method stands out for its technical precision and practical applicability. Its scalable design makes it ideal for integration into the third cycle of the EU Floods Directive planning, supporting authorities in making informed decisions and improving protection against increasingly complex natural disasters.
