Abstract

Owing to the rare occurrence of tsunamis in the Arabian Sea, and the lack of reliable records on them, tsunami preparedness has not been prioritized in plans for the development of coastal cities in the Middle East. However, an increase in the number of earthquakes in the region in the recent past has highlighted the vulnerability of low-lying coastal areas to tsunamis. We investigate the potential of date palm forests to mitigate tsunamis in the Middle East. Experiments were conducted at a scale of 1:100 to assess the effectiveness of forests in reducing the intensity of tsunamis. The reflection at the front of the forest was negligibly small when the depth of flow was lower than the height of the canopy, and increased with the height of the tsunami wave when the depth of flow was higher than the height of the canopy. This shows that the structure of the canopy of date palm trees is key to reducing the energy of the tsunami. The reduction in the maximum depth of flow behind the forest increased with the height of the tsunami when the forest was longer than 120 m. The largest reductions obtained in the depth and velocity of flow behind the forest were 37% and 40%, respectively, when the forest was 180 m long and the tsunami wave was 7 m high. The results suggest that a date palm forest with a length of at least 150 m on flat ground can mitigate tsunamis in the Middle East.

利用椰枣林缓解中东海啸的实验调查

摘要由于阿拉伯海很少发生海啸，也缺乏有关海啸的可靠记录，在中东沿海城市的发展规划中，海啸防备没有被列为优先事项。然而，最近该地区地震次数的增加凸显了低洼沿海地区易受海啸影响的脆弱性。我们研究了椰枣林缓解中东海啸的潜力。我们以 1:100 的比例进行了实验，以评估森林在降低海啸强度方面的有效性。当水流深度低于树冠高度时，森林前端的反射很小，可以忽略不计；当水流深度高于树冠高度时，森林前端的反射随着海啸波高度的增加而增加。这表明，椰枣树冠的结构是降低海啸能量的关键。当森林长度超过 120 米时，林后最大水流深度的减少量随海啸高度的增加而增加。当森林长度为 180 米、海啸波高为 7 米时，林后水流深度和速度的最大减少量分别为 37% 和 40%。研究结果表明，在平地上种植长度至少为 150 米的椰枣林可以缓解中东地区的海啸。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
