Implementation of Wave Dissipation by Vegetation in STWAVE
Abstract
The influence of vegetation on coastal hydrodynamics is a relatively new field, with a body of literature documenting the dissipation of wave energy by coastal vegetation developing within the last few decades (see Anderson et al. (2011) for a summary). Unfortunately, the effect of vegetation on coastal processes and hydrodynamics is not fully implemented in many numerical models. Standard practice in nearshore wave propagation models, including STWAVE and SWAN, is to account for energy losses due to vegetation using bottom friction source terms. The need to accurately predict coastal hydrodynamics in the presence of natural or nature-based features has led to an increasing demand for models that better capture wave interaction with vegetation. Compounded by a lack of technique and guidance, the beneficial effects of vegetation are often neglected in the analysis, design, and construction of coastal protection.
