Abstract
The ability of coastal vegetation to attenuate waves has been well established (Moller et al., 2014). Salt marshes are vegetated coastal wetlands that can act as nature- based coastal defenses. They exhibit a range of plant species, which have been shown to differ in the amount of wave damping they provide (Mullarney & Henderson, 2018). Recent studies have shown that plant flexibility is a key parameter that controls wave energy dissipation (Paul et al., 2016). Yet, no model exists that includes plant flexibility in computationally efficient manner for large-scale coastal zones. Therefore, we have developed a new model for flexible vegetation based on the key mechanisms in the wave-vegetation interaction and applied it to an estuary with diverse salt marsh vegetation.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/AjnFx3aFSzs
Highlights
The ability of coastal vegetation to attenuate waves has been well established (Möller et al, 2014)
A new model which considers the two-way wave-vegetation interaction was developed for flexible vegetation, including the effect of wave forcing on plant motion and the feedback of plant motion on wave forces
The town of Laugharne relies on salt marshes for flood protection as no hard defenses are in place
Summary
The ability of coastal vegetation to attenuate waves has been well established (Möller et al, 2014). Attenuation, wave velocity fields and plant motion (Fig. 2) were measured simultaneously for the first time. The key physics in the wave-vegetation interface were identified based on this combined dataset.
