进行了一项实验研究，以确定沿海森林对海啸抬头高度的影响。该海滩是以实验室规模的天然沙滩建造的。使用人工树(FM-I)和圆柱形木棍(FM-II)构建了沿海森林模型。人工林木按1：5的比例放置在三种不同的布局上：直线、交错和密集直线。结果表明，当树木呈密集直线排列并接近静水位时，爬升高度比没有树木的情况降低了约45%。在对实验结果进行评价后，确定了影响爬升高度的参数。利用白金汉的PI定理，这些参数被写成一个无量纲群。进行了广泛的回归分析，提出了回归方程。此外，所有实验都在斜率为1：3.5的情况下重复进行，以验证所提出的方程。将实验结果与所提出的方程结果进行了比较，结果表明两者吻合较好。
An experimental study was carried out to determine the effects of a coastal forest on tsunami run-up heights. The beach was built as a natural sandy beach at laboratory scale. The coastal forest model was constructed using artificial trees (FM–I) and cylindrical timber sticks (FM–II). Artificial trees were placed on a 1:5 slope in three different layouts: rectilinear, staggered, and dense rectilinear. It was shown that in the case when the trees were placed in the dense rectilinear pattern and close to the still water level (SWL), the run-up height was reduced by approximately 45% compared with the case without trees. After evaluation of the experimental results, the parameters that affect the run-up height were determined. These parameters were written as a dimensionless group using Buckingham's Pi theorem. An extensive regression analysis was carried out and equations proposed. Furthermore, all experiments were repeated with a slope of 1:3.5 to verify the proposed equations. The experimental results were compared with the results of the proposed equations, and it was shown a good agreement between the results.
