“…The first event led to wave heights in excess of 6 m at the Aberporth Buoy and nearly the same value in the Bristol Channel Buoy. The second one caused wave heights >4 m at the WaveNet Buoy in Pool bay, with periods of about 20 s. Both events caused damages to coastal structures and flood warnings [36].…”

“…This event occurred on the 14th of February 2014 and the driving storm also led to the highest return period on record in site 16 and had a large spatial footprint, affecting five sites in the SW and SE regions. Waves were reported to have reached 7.5 m at the Channel Light Vessel and caused coastal flooding along the English Channel [36].…”

“…The event with the largest footprint led to a maximum return period of 15 years that was reached at site 18 on the 5th of February 2014 and is ranked 10th but was not the maximum return period recorded for any site. During this extreme event, very large swell waves were reported breaking against the coast of West Wales, Cornwall and also parts of Northern Ireland and Scotland due to the joint action of waves and the storm surge [36].…”

Densely populated coastal regions are vulnerable to extreme wave events, which can cause loss of life and considerable damage to coastal infrastructure and ecological assets. Here, an event-based analysis approach, across multiple sites, has been used to assess the spatial footprint and temporal clustering of extreme storm-wave events around the coast of the United Kingdom (UK). The correlated spatial and temporal characteristics of wave events are often ignored even though they amplify flood consequences. Waves that exceeded the 1 in 1-year return level were analysed from 18 different buoy records and declustered into distinct storm events. In total, 92 extreme wave events are identified for the period from 2002 (when buoys began to record) to mid-2016. The tracks of the storms of these events were also captured. Six main spatial footprints were identified in terms of extreme wave events occurrence along stretches of coastline. The majority of events were observed between November and March, with large inter-annual differences in the number of events per season associated with the West Europe Pressure Anomaly (WEPA). The 2013/14 storm season was an outlier regarding the number of wave events, their temporal clustering and return levels. The presented spatial and temporal analysis framework for extreme wave events can be applied to any coastal region with sufficient observational data and highlights the importance of developing statistical tools to accurately predict such processes.

“…While coasts of Northeast Asia facing the Northwestern Pacific Ocean have rarely experienced storm surges during winter season, there is a number of disaster reports on winter storm surges in coasts of Europe along the North Sea and the Northeastern Atlantic Ocean, e.g., [Lamb and Frydendahl, 1991;Bertin et al, 2012;Sibley et al, 2015]. Langenberg [Langenberg et al, 1999] found that there is an increasing tendency in extreme sea level events induced by winter storms in coasts in the North Sea and related it to changes in climate which may be enhanced by global warming.…”

From Tuesday, December 16, 2014, until Thursday, December 18, Hokkaido was battered by strong winds and high sea waves caused by a passing low pressure system intensified to typhoon levels. In the city of Nemuro, a rise in sea level influenced by the storm surge which exceeded quay height in port areas was observed from predawn Wednesday, December 17, 2014. Flooding was experienced in areas of central Nemuro, the Nemuro Port and estuaries of rivers. This technical note provides a comprehensive meteorological analysis and the results of a local flood survey carried out by the authors from December 19 to 21, 2014, and summarizes the characteristics of the 2014 Nemuro storm surge disaster

“…The low pressure system moved quickly across the Atlantic and deepened to the west of Ireland at 0000 3 January UTC. Further meteorological details, including pressure charts of Storm A, can be found in [15]. The movement and development of the storm enabled the creation of trapped fetch conditions, where long-period swell waves are created and travel at the same speed as the storm.…”

Abstract:The work presents a methodology to assess the coastal impacts during a storm event which caused significant damage along the promenade at Aberystwyth, Wales on the 3 January 2014. Overtopping was analysed in detail for a section of promenade by downscaling offshore wave conditions to force a surf zone hydrodynamic model, NEWRANS. Overtopping discharges are computed and were in qualitative agreement with published discharges for the level of damage observed along the promenade. Peak storm conditions were observed to arrive just before and during high tide at Aberystwyth, which in addition to a storm surge and wave-setup, contributed to the damage observed. A high frequency of overtopping occurs during peak high tide, with overtopping also occurring in the hour leading up to and following high tide. Finally, comparisons to design methods for the estimation of overtopping discharge were made. Current empirical formulae underestimated the peak overtopping event at high tide. The methodology applied is generic and applicable to any location.
