“…Coastal flooding is mainly due to the joint action of waves, tides, surges, riverine, and rain processes. Many studies highlight the importance of considering the interaction between those properties [4,6,13,15,51,52]. Hence, coupling the present spatial and temporal analysis of extreme waves with extreme surge events and tides would provide a more holistic approach to deal with flooding issues.…”

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.

“…Hence, the question arises as to whether the North Sea fauna and flora is currently in a gene flow -genetic drift -selection -mutation equilibrium. In a contemporary perspective, sand gobies live in a very dynamic environment with strong tidal currents and experience heavy wave action due to the shallow water depth (Otto et al, 1990;Ozer et al, 2000). However, their preferred mating habitat seems to focus on two regions in the Southern Bight.…”

Evidence for fine-scale genetic structure and estuarine colonisation in a potential high gene flow marine goby (Pomatoschistus minutus)

Marine fish seem to experience evolutionary processes that are expected to produce genetically homogeneous populations. We have assessed genetic diversity and differentiation in 15 samples of the sand goby Pomatoschistus minutus (Pallas, 1770) (Gobiidae, Teleostei) from four major habitats within the Southern Bight of the North Sea, using seven microsatellite and 13 allozyme loci. Despite its high dispersal potential, microsatellite loci revealed a moderate level of differentiation (overall F ST ¼ 0.026; overall R ST ¼ 0.058). Both hierarchical analysis of molecular variance and multivariate analysis revealed significant differentiation (Po0.01) between estuarine, coastal and marine samples with microsatellites, but not with allozymes. Comparison among the different estimators of differentiation (F ST and R ST ) pointed to possible historical events and contemporary habitat fragmentation. Samples were assigned to two breeding units in the estuary and coastal region. Despite this classification, there were indications of a complex and dynamic spatiotemporal structure, which is, most likely, determined by historical events and local oceanic currents.

“…In the presence of currents it is the wave action which is conserved rather than wave energy. All these processes are described in more detail in Wolf et al (1988), Osuna and Wolf (2005) and Ozer et al (2000).…”

Although some interaction processes have been shown to produce a significant effect, a clear demonstration that coupled models give consistently better results than tuned separate models is required to persuade operational agencies to adopt them (Ozer et al, 2000). In the EU PROMISE project, Monbaliu et al (1999Monbaliu et al ( , 2000 developed a version of WAM (here termed ProWAM) more suited to shallow water and high resolution.…”

Wind waves and elevated water levels together can cause flooding in low-lying coastal areas, where the water level may be a combination of mean sea level, tides and surges generated by storm events. In areas with a wide continental shelf a travelling external surge may combine with the locally generated surge and waves and there can be significant interaction between the propagation of the tide and surge. Wave height at the coast is controlled largely by water depth so the effect of tides and surges on waves must be also be considered, while waves contribute to the total water level by means of wave setup through radiation stress. These processes are well understood and accurately predicted by models, assuming good bathymetry and wind forcing is available. Other interactions between surges and waves include the processes of surface wind-stress and bottom friction as well as depth and current refraction of waves by surge water levels and currents, and some of the details of these processes are still not well understood. The recent coastal flooding in Myanmar (May 2008) in the Irrawaddy River Delta is an example of the severity of such events, with a surge of over 3m exacerbated by heavy precipitation. Here we review the existing capability for combined modelling of tides, surges and waves, their interactions and the development of coupled models.Keywords: tides, storm surges, wind waves, coastal flooding, wave-current interaction, numerical modelling 1 Coastal Flooding -Impacts of coupled wave-surge-tide models Judith Wolf AbstractWind waves and elevated water levels together can cause flooding in low-lying coastal areas, where the water level may be a combination of mean sea level, tides and surges with storm surges and waves often being generated by the same storm event.
