外文摘要：As an essential coastal ecological protection system, mangroves are capable of wave dissipation, shore protection and biodiversity conservation. To explore how spatial arrangements regulate the attenuation of regular waves by mangroves, this study employs the open-source code DualSPHysics. Mangrove plants are simplified as rigid cylinders, and a three-dimensional numerical wave flume is established. Wave attenuation characteristics are systematically investigated for four typical layouts: uniform arrangement, staggered arrangement, clustered arrangement (uniform cluster, non-uniform cluster and staggered cluster), and row-column angle arrangement. Validated by physical model tests, the setting of Rdp = 10 balances simulation accuracy and computational efficiency, and satisfies the requirements of engineering simulation. The results demonstrate that layout patterns exert a remarkable influence on wave attenuation performance under fixed plant density and bandwidth. The rectangular arrangement achieves the optimal wave dissipation effect yet presents poor ecological compatibility. The staggered layout boasts superior ecological performance and enhances the structural resilience. The staggered cluster arrangement combines high wave reduction efficiency with favorable ecological characteristics. For uniform clustered layouts, an inter-cluster spacing of 0.4 m realizes coordinated protection with strong energy dissipation and weak wave reflection. Regarding layouts with varying row-column angles, the configuration at 70 degrees delivers excellent wave attenuation and wave surface stability, showing the best practical applicability. This study clarifies the wave dissipation mechanisms and applicable scenarios of different arrangements, and establishes fitting correlations for key coefficients and parameters. The findings can provide a theoretical reference for layout optimization of mangrove ecological revetment projects.
