The 3rd International Workshop on swash-zone processes

The 3rd International Workshop on Swash-Zone Processes, held in Rome, Italy in September 2024, brought together researchers to discuss the current challenges in swash-zone research. Through review presentations and a structured method, participants identified knowledge gaps and proposed ideas to address those gaps. Areas discussed included: hydrodynamics, runup, sediment transport, morphodynamics, infiltration, and the application of remote sensing and numerical modeling for swash-zone research. The workshop emphasized the need for better integration of spatially extensive data (e.g., from drones and lidar) with traditional methods, and highlighted the importance of collaboration and standardized data sharing. Additionally, discussions focused on improving numerical models of sediment dynamics and understanding of 3D hydrodynamic/morphodynamic processes. This editorial outlines the key knowledge gaps identified and the strategies proposed to address them, offering suggestions for future swash-zone processes research. • 3rd Intl Workshop (Rome, Sept 2024) united experts on swash-zone challenges. • Workshop used review presentations & structured discussions to pinpoint solutions. • Identified gaps in hydrodynamics, sediment transport, infiltration & modeling. • Recs: Develop new in situ sensors; expand remote sensing; boost model validation. • Recs: Standardize data protocols & foster collaboration among teams.
