The integration of oscillating water columns (OWCs) with piles to create a dual-function OWC-pile breakwater presents an innovative approach for harbor construction and coastline protection while enabling wave energy utilization. Local scour significantly impacts foundation safety and is crucial for structural design. This study examines wave-induced local scour at a dual-function OWC-pile breakwater through experimental methods. A high-resolution laser scanner tracked the development of 3D local scour profiles at various time intervals under regular wave conditions. The analysis focused on ke...
