Abstract
A fully explicit coupled wave-vegetation interaction model has been developed to efficiently solve the coupled wave dynamics and flexible vegetation motion with large deflections. The flow model is formulated using the continuity equation and linearized momentum equations of an incompressible flow, with additional terms within the canopy region accounting for the presence of vegetation. A second-order unconditionally stable explicit scheme is developed to solve the linearized flow model. A truss-spring model is proposed to capture the vegetation motion with substantial deflections, allowing for explicit time integration with large time steps when dealing with highly compliant vegetation. The coupled model is first validated against experiments on the reconfiguration of an elastic blade in oscillatory flow and then employed to investigate wave propagation over a floating seaweed farm, demonstrating its efficiency and robustness in addressing wave-vegetation interaction problems.
