Coastal areas are threatened by extreme meteorological phenomena, such as wave storms. Therefore, the analysis of such events, such as providing information for their potential hazards assessment, is a key element in coastal management. In this study, a preliminary assessment of flood vulnerability due to storms was performed in Rhodes Island, Greece. Firstly, storm events were defined in terms of significant wave height, peak period, and duration, and they were grouped by means of cluster analysis into five classes (from weak to extreme) reflecting the intensity of each event. Subsequently, flood hazard was assessed by using an empirical formula for wave run-up calculations on cross-shore profiles and storm surge data at the region. Finally, a Flood Vulnerability Index (FVI) was used for assessing vulnerability according to a scale from very low to very high. The most intense storms were found to occur in the eastern, southeastern, and southern part of the island. More than 60% of storms were classified as weak, while extreme events were found to occur with a frequency of less than 2.5%. Regarding flood hazard and vulnerability, the maximum values of wave run-up were calculated in the southeastern region, but the most vulnerable part was found to be the northwestern region, as the FVI was assessed as very high for weak and extreme events.

希腊罗德岛波浪风暴诱发洪水脆弱性评估

沿海地区受到极端气象现象的威胁，例如海浪风暴。因此，对此类事件的分析，例如为其潜在危害评估提供信息，是沿海管理的关键要素。在这项研究中，对希腊罗得岛因风暴造成的洪水脆弱性进行了初步评估。首先，根据显着波高、高峰期和持续时间定义风暴事件，并通过聚类分析将它们分为五个等级（从弱到极端），反映每个事件的强度。随后，通过使用经验公式对跨海岸剖面和该地区的风暴潮数据进行波浪爬高计算，对洪水危害进行了评估。最后，洪水脆弱性指数 (FVI) 用于根据从非常低到非常高的等级评估脆弱性。最强烈的风暴发生在该岛的东部、东南部和南部。超过 60% 的风暴被归类为弱风暴，而极端事件的发生频率低于 2.5%。在洪水灾害和脆弱性方面，计算了东南地区波浪爬高的最大值，但发现最脆弱的部分是西北地区，因为弱和极端事件的 FVI 被评估为非常高。
