국문 초록

Artificial reefs are widely deployed to enhance coastal ecosystems, yet quantifying their hydraulic behaviour and the ecological opportunities they create remains challenging. Gukdo Island, set in a rias-type archipelago on the southeastern coast of Korea, combines persistent tidal currents with high fish biodiversity, providing an ideal pilot area for testing a science-based pre-installation workflow. A regional ocean tidal model (EFDC) reconstructs multi-directional flows around the island and supplies boundary conditions to CFD simulations (FLOW-3D). Three scalar descriptors—velocity-change ratio, axis-specific vorticity, and turbulent kinetic energy—are mapped three-dimensionally and expressed as dimensionless volumes corresponding to potential feeding and refuge habitats. The results indicate that cubic block-type reef modules positioned in the modelled acceleration, deceleration, and vortex zones can create nutrient-rich upwelling sites while preserving low-energy shelters for juvenile fish, thereby maximising habitat heterogeneity. Building on these findings, a sequential screening framework is outlined: it starts with collating target-species ecological data, continues with regional hydrodynamic site selection and CFD-assisted layout optimisation, and ends with adaptive field monitoring and modular retrofit. Although demonstrated under steady tidal forcing, the workflow offers a transferable template for aligning reef design with species-specific hydraulic preferences and establishing evidence-based installation standards.
