## Abstract
Integrating coastal protection functions and wave energy conversion makes the OWC breakwater an environmentally friendly and material-efficient innovation compared to conventional breakwaters. This research aims to determine the wave runup height on the Sloped side of the OWC breakwater model and its internal pressure. Utilizing theoretical approaches, a 1:20 scale laboratory model, dimensional analysis, and parameter relationships, the study investigates the effects of wave interaction, model geometry, and water depth. The analysis reveals a positive correlation between the combined parameter value (𝜓) and relative pressure (P/ρghs), highlighting the consistent influence of these parameters on pressure behavior. Results show that a lower slope angle increases pressure, while variations in inlet opening sizes (hs) significantly affect wave runup (Ru/Hi) and run-down (Rd/Hi). Larger inlet openings generally reduce the wave runup effect, though the magnitude of this impact depends on the slope angle. The optimal configuration for the OWC breakwater model is identified as an inlet opening size between 5 cm with a slope angle of 45° to 60°, providing relatively higher pressure while maintaining stability. This combination improves the system's efficiency in absorbing and using wave energy. Doi: 10.28991/CEJ-2025-011-04-02 Full Text: PDF
