Abstract

This paper presents a comprehensive investigation of the storm damage at a commercial port located in the Southwestern Black Sea Region that occurred on January 18–19, 2018. One week after the event, a field survey was conducted at the port focusing on significantly damaged mound breakwaters and protection structures that failed at several sections. A numerical wave modeling study is carried out to estimate the wave characteristics at deep sea, nearshore, and inside the port to assess the observed damage during the field survey. Widely used numerical models WAVEWATCH III, SWAN, and SWASH are utilized using nested computational domains and calibrated based on satellite measurements. As a result, the significant wave height of the storm is estimated as 7.8 m with a peak period of 12.4 s near the port area, approaching mainly from the northwest direction. The damage mechanisms of the mound structures are discussed based on the field observations and the wave modeling studies. The insufficient seaside armor unit sizes and the orientation of the breakwaters are found to be the main reasons for the damage.

黑海西南部港口的风暴损害评估

本文介绍了对 2018 年 1 月 18-19 日发生在黑海西南部地区一个商业港口的风暴破坏的全面调查。事件发生一周后，对该港口进行了实地调查，重点是受损严重的土墩防波堤和多个部分失效的保护结构。为估算深海、近岸和港口内部的波浪特性，对实地勘测期间观察到的损坏情况进行了数值波浪建模研究。广泛使用的数值模型 WAVEWATCH III、SWAN 和 SWASH 采用嵌套计算域，并根据卫星测量结果进行校准。结果，风暴的显著波高估计为 7.8 米，在港口区附近的峰值周期为 12.4 秒，主要从西北方向接近。根据现场观测和波浪模型研究，讨论了土墩结构的破坏机制。发现海边装甲单元尺寸不足和防波堤的朝向是造成破坏的主要原因。

期刊介绍： Coastal Engineering is an international medium for coastal engineers and scientists. Combining practical applications with modern technological and scientific approaches, such as mathematical and numerical modelling, laboratory and field observations and experiments, it publishes fundamental studies as well as case studies on the following aspects of coastal, harbour and offshore engineering: waves, currents and sediment transport; coastal, estuarine and offshore morphology; technical and functional design of coastal and harbour structures; morphological and environmental impact of coastal, harbour and offshore structures.
