Abstract
Wave modeling has become increasingly important in coastal engineering, particularly for understanding sea wave behavior and assessing the performance of protective structures. Researchers often employ flume wave makers, which allow precise replication of wave characteristics to study wave dynamics in controlled conditions. Floating breakwaters present a cost-effective alternative to conventional fixed structures, especially in areas with relatively mild wave climates, and are frequently used to protect harbors, marinas, and shorelines from erosion. In this study, the performance of three floating breakwater designs was evaluated, with each constructed from recycled plastic bottles to assess the feasibility of incorporating post-consumer materials in coastal infrastructure. The prototypes varied in submersion levels which 0% submerged, 50% submerged and 70% submerged. These models were tested under different wave conditions in amplitude and frequency, to determine their effectiveness in reducing wave height and transmission. The objective was to identify the configuration that offered the greatest wave attenuation under conditions representative of real coastal environments, thereby providing insight into the optimal design for practical application in sustainable coastal engineering.
