Beach nourishment is generally seen as the preferred means of rectifying coastal erosion, due to its low environmental impact and natural evolution. The largest beach nourishment project ever carried out in Mexico took place on Cancun beach in 2006, as a response to the most intense hurricane season ever registered in Mexico, in 2005. After Hurricane Dean, in 2009, a second nourishment was conducted, which evidenced flaws in the design and execution of the first project. Previous investigations report that the need for beach re-fills directly correlates with wave energy. However, following a thorough revision of the extreme climatic events that occurred between 1978 and 2018, it has been found that the amount of erosion also depends on the frequency and duration of high energy events. The findings also show that the apparent success of the second nourishment is mainly associated with a decline in the number of extreme wave power events impacting the beach. In the conclusion to this paper, we share the knowledge gained, but not yet applied, in Mexico or elsewhere, regarding beach use, urbanization, and protection in beach planning.

坎昆的海滩营养如何有效?

由于海滩养分对环境的影响小和自然演化,通常被认为是纠正海岸侵蚀的首选手段。墨西哥有史以来规模最大的海滩营养项目是2006年在坎昆海滩进行的,这是对2005年墨西哥有史以来最强烈的飓风季节的回应。在2009年迪恩飓风之后,进行了第二次营养,这证明了在第一个项目的设计和执行中存在缺陷。先前的调查报告称,海滩重新填充的需求与波浪能直接相关。但是,在对1978年至2018年间发生的极端气候事件进行彻底修订后,发现侵蚀量还取决于高能事件的发生频率和持续时间。研究结果还表明,第二种营养的明显成功主要与影响海滩的极端波浪发电事件数量减少有关。在本文的结论中,我们分享了在墨西哥或其他地方获得但尚未应用的有关海滩使用,城市化和海滩规划保护的知识。
