Abstract

This paper presents a coupled wave-vegetation interaction model suitable for very flexible vegetation with large deflections. The wave hydrodynamics is modeled by a Navier-Stokes flow solver along with a Volume of Fluid surface capturing method. The governing equation for flexible vegetation motion is solved by a Finite Element Method using a semi-implicit time differencing scheme. The coupling between wave hydrodynamics and vegetation motion is achieved using an immersed boundary method. The model is validated with experimental measurements for a single-stem vegetation and a large-scale vegetation patch in a wave flume.
