The Effects of a Triangular Floating Platform and Dual Surface-piercing Thin Barriers over a Sloped Bottom on Wave Reflection
Main Article Content
Abstract
This study analytically investigates the wave reflection from a triangular floating platform in conbination with dual surface-piercing thin barriers over a sloped bottom using the eigenfunction matching method (EMM). The problem is formulated with linear water wave theory; eigenfunction expansions describe wave interactions across regions with varying bathymetry and boundaries. By imposing continuity of velocity potential and pressure at interfaces, a numerically solvable system is established. Reflection coefficients are analyzed with varying platform, barrier, and seabed parameters. Results show that barrier configuration and seabed slope significantly affect the reflected wave. The findings inform the design of structures for wave energy dissipation, platform protection, and nearshore barriers.
