在劳拉飓风（2020 年）期间和之后收集的现场观测结果的指导下，XBeach 模型用于模拟美国路易斯安那州西南部洛克菲勒野生动物保护区有或没有低顶防波堤时飓风对形态动力学的影响，包括海岸侵蚀和过度冲刷。现场数据显示了研究地点的自然和基于自然的基础设施提供的地表流量和风暴潮以及波浪衰减（防洪）的时空变化。模型结果显示了正确模拟湿地植被影响的重要性。植被生物力学特性需要纳入数值模型中，以准确模拟飓风对自然和混合基础设施的影响。这些结果通过平衡灰色（硬）方法、自然和基于自然的基础设施（NNBI）和混合解决方案，对沿海保护的成本管理产生影响。
Guided by field observations collected during and after Hurricane Laura (2020), the XBeach model is used to simulate the hurricane impact on morphodynamics, including shore erosion and overwash, with and without the low-crested breakwater at the Rockefeller Wildlife Refuge in southwestern Louisiana, USA. The field data demonstrates the spatiotemporal variation in overland flow and storm surge and wave attenuation (flood protection) provided by the natural and nature-based infrastructure at the study site. The model result shows the importance of modeling wetland vegetation effects properly. Vegetation biomechanical properties need to be incorporated into the numerical models to accurately simulate the impact of hurricanes on natural and hybrid infrastructure. These results have implications for cost management in coastal protection via the balancing of gray (hard) approaches, natural and nature-based infrastructure (NNBI) and hybrid solutions.
