Summary: The South Pacific region is vulnerable to extreme total water levels due to the lack of wide continental shelves that can dissipate waves. This study examined the waves and storm surge induced by severe TC Harold in 2020 on Tongatapu using advanced hydrodynamic and wave models. The contributions of winds, atmospheric pressure, waves, and wave-radiation-stress-induced setup to extreme total water levels were analysed. The suite of models used in this study can support the Tonga Meteorological Service Tropical Cyclone Early Warning System.

Summary: Dynamically-coupled SWAN and ADCIRC models have been used to improve the prediction of extreme waves and storm surges in the Gulf of Mexico caused by hurricanes and sea level rise. The performance of the models was evaluated using Hurricane Michael as a case study, and the results showed that the dynamically-coupled models significantly increased the accuracy of the simulations compared to the stand-alone SWAN model.

Summary: This study used a coupled model to analyze the dynamic processes during typhoons and extratropical storms near the Shandong Peninsula. The results showed that the interaction between water level change and waves mainly occurred in the nearshore zone, while wave-current interaction mainly occurred in the offshore zone. The modulations of water level and wave height were strongly dependent on storm characteristics and coastal features.

Summary: This study evaluates the contribution of waves to storm surges predicted in Hurricane Irma hindcast, using ADCIRC+SWAN and ADCIRC models. Waves were found to have the largest contribution to total water levels on the south and northeast coasts, while the continental shelf on Florida's west coast plays a critical role in decreasing significant wave heights and sheltering coastal areas from large wave effects.

Summary: Storm surge is a significant natural hazard in coastal regions, and accurate models are needed for predicting its impact. Traditional ocean circulation models are computationally expensive, leading to the development of data-driven surrogate models. This study presents a novel surrogate model for predicting peak storm surge, which shows comparable accuracy to traditional models but with much faster computational speed. The model is tested in Texas and Alaska, yielding promising results.

Summary: Coastal flooding models are used to predict inundation during storms, and the need for faster flooding predictions that also represent flow pathways and barriers can be addressed through subgrid corrections. Recent studies have shown a significant decrease in run time by implementing subgrid corrections in a finite-element-based shallow water model, improving accuracy and efficiency of inundation predictions by increasing model speed by 10 to 50 times.

Summary: Hurricane Irma in 2017 posed challenges to the evacuation process in South Florida due to its unpredictability. This study developed a methodology integrating evacuation and storm surge modeling, showing that approximately three days are needed to safely evacuate the population in the study area. Integrated simulations before the hurricane hit the state could provide crucial information for decision-making on evacuation in hurricane-prone areas.

Summary: This study simulated the potential impact of sea level rise on the Chesapeake Bay regions in the United States, showing that increased flooding and property damages could be significant. The reduction of wetlands in the future scenarios could exacerbate these impacts.

Summary: The vulnerability to coastal disasters resulting from storm surges and wave overtopping is increasing due to rising sea levels. This study used a unified modeling system to simulate the vulnerability to wave overtopping in the Northwest Pacific Ocean. The results showed that vulnerability to wave overtopping intensifies with rising sea levels. The integrated model can be used for long-term coastal protection design and short-term storm surge early warning systems.

Summary: This study examines the potential impact of deepening the Corpus Christi Ship Channel on hurricane storm surge in the region of Corpus Christi and Port Aransas, Texas. Using numerical mathematical models, the study compares the effects of current and proposed future channels on storm surge magnitude. The results indicate that the changes to maximum storm surge are minimal, with some localized areas showing a potential increase of up to 30 centimeters in a synthetic extreme storm scenario.

Summary: Tide-surge interaction (TSI) is a critical factor in assessing flooding in shallow coastal systems, particularly in estuaries and harbours. The occurrence and impact of TSI on water levels in New Zealand have not been extensively studied. TSI was found to occur at most sites in New Zealand and primarily affects the timing of surges relative to high tide. The strongest TSI occurred in inner estuarine locations and was correlated with the intertidal area. Co-occurrence rates of extreme water levels in estuaries varied with TSI modulating the rate by affecting tidal amplification. Further investment in the tide gauge network is needed to provide more accurate observations and incorporate TSI in flooding hazard projections.

Summary: Storm-surge models are used to assess the impacts of hurricanes and coastal storms in coastal areas, and including sea level rise is necessary for realistic flood risk assessment. Linear superposition of sea level rise may lead to inaccuracies, while developing a nonlinear model is time-consuming. By comparing the linear and nonlinear approaches, it is found that the linear approach is generally conservative in predicting flood elevations compared to the nonlinear approach.

Summary: A numerical modeling study was conducted to simulate storm surge during Hurricane Michael in 2018, using the ADCIRC hydrodynamic model with high-resolution mesh. Two parametric wind models, Holland 1980 and Holland 2010, were evaluated for their accuracy in predicting storm surge, with results showing errors between 1% and 3.7% for maximum water levels in Mexico Beach. The study suggests that the Holland 1980 wind model with a 64-knot wind speed radius for parameter estimation produced the lowest error of 1%.
