Coastal vegetation plays an important role in creating habitats, as a carbon sink and by dampening the waves as a natural form of coastal protection. This project aims to improve the understanding of wave dampening and related changes to boundary layers by vegetation through the use of novel simulation methods. Resolving many relatively small details like 100-1000s of plant stems in the same simulation framework as several wavelengths across the computational domain is still too computationally demanding using conventional computational fluid dynamics to geometry-resolving methods. ALFEA, a recently created tool based on Actuator Line Theory coupled with a Finite Element Structural Solver, shows promise in not only resolving the effect of large numbers of fixed stems, but also offers opportunities to investigate the effect of plant rigidity and deformation under fluid loading.This project will firstly assess the accuracy and suitability of ALFEA for such simulations by performing validation studies against published data for static and flexible stems.

沿海植被在创造生境方面发挥着重要作用，作为碳汇，并作为海岸保护的自然形式抑制海浪。该项目旨在通过使用新的模拟方法，提高对植被对波浪阻尼和边界层相关变化的理解。在相同的模拟框架中解析许多相对较小的细节，如100- 1000个植物茎，作为跨计算域的几个波长，使用传统的计算流体动力学到几何解析方法仍然在计算上要求太高。ALFEA是最近创建的一种基于致动器线理论与有限元结构求解器相结合的工具，不仅可以解决大量固定股骨柄的影响，该项目将首先通过对已发表的静态数据进行验证研究，评估ALFEA对此类模拟的准确性和适用性。和灵活的茎。
