Summary: This study investigates the relationship between extreme water levels and astronomical tides and storm surges using water level data from the Xiamen tide gauge station. The results show that the astronomical tide component contributes significantly to the total water level during typhoon events. Additionally, it is found that typhoons Herb (1996) and Dujuan (2015) cause higher extreme tide levels compared to other typhoons and correspond to longer return periods. The study also estimates the impact of typhoon surges on water levels and highlights the importance of sea level rise in determining the water level return period.

Summary: This study used a coupled tide-surge-wave model to hindcast historical Typhoon Nepartak (2016) and analyze tide-surge and wave interactions. The model results showed that onshore wind enhanced surge height, atmospheric pressure had a positive contribution to surge height, and the path of typhoons at different time frames significantly affected the spatial distributions of surge height and wave height around the coast of Taiwan.

Summary: This study investigated tide-surge interactions induced by Typhoon Mangkhut in the Pearl River Estuary using a numerical model. The results showed that the typhoon caused nonlinear oscillations in the bay, with peak values not coinciding with the highest stage of the surge. Further analysis revealed that the nonlinear oscillations were influenced by tides, with stronger oscillations occurring under larger tidal ranges. Additionally, nonlinear bottom friction was identified as the major factor contributing to the significant nonlinear oscillations.

Summary: This study proposes a methodology for quantitative risk assessment of storm surge in coastal cities using GIS techniques and open data. By simulating typhoon scenarios with different return periods, analyzing building footprint data, identifying exposed elements, and combining them with depth-damage functions, the study provides the basis for developing risk mitigation strategies and urban plans. The quantitative risk assessment and zonation maps can help prioritize sub-zones likely to be affected by storm surge and inform decision-making for local authorities.

Summary: In this study, the impact of wind drag coefficient on storm surge level forecast was investigated in the Bohai Sea, Yellow Sea, and East China Sea for Typhoons 7203 and 7303. The results showed that non-zero initial values of the wind drag coefficient outperformed zero initial values, with Wu's method exhibiting the best performance. Data assimilation-based coefficients showed better performance compared to ordinary coefficient formulas, and a linear formula for wind drag coefficient performed slightly better than a constant formula when using data assimilation method. The storm surge model with a combination of four constituents and the wind drag coefficient inverted by data assimilation method with linear C-d demonstrated the best performance.

Summary: The study found that the forecast errors of storm surges are mainly attributed to the typhoon track forecast, and the parametric typhoon model tends to overestimate the surge height. The parametric Holland typhoon model using WRF output performs well in forecasting the surge height near the typhoon and its peak occurrence time.

Summary: Mangroves play a significant role in providing coastal protection, as demonstrated in a study conducted in Shanwei, Guangdong Province, China, where a planted mangrove forest was found to reduce wave height by 77% during a typhoon. The study concludes that a six-year-old mangrove forest with a width of around 100 meters can effectively withstand the impact of a super typhoon and offer substantial protection for fish ponds and embankments. No major damage was observed, although some defoliation occurred in certain areas within the mangrove forest.

Summary: This study utilized remote sensing measurements to examine storm surges and sea surface cooling caused by typhoons in Chinese coastal waters. Altimetric data from satellite altimeters were used to determine the characteristics of storm surges, while the remote sensing sea surface temperature product was used to analyze sea surface cooling. The results were consistent with theoretical models and tide gauge data, showing the propagation of storm surges as continental shelf waves along the southeastern coast of China. The study highlights the benefits of incorporating remotely sensed measurements in understanding oceanic responses to typhoons, complementing traditional tide gauge network and buoy data.

Summary: This study developed an integrally-coupled tide-surge wave model to simulate storm tides and waves in the coastal area of Qingdao. The results showed that sea level rise and typhoon intensification had significant impacts on tides within Jiaozhou Bay, with a greater effect during the flood and ebb period. The study also revealed that the effects of sea level rise and typhoon intensification on storm tides and waves varied and were different in Jiaozhou Bay and along the open coast. Therefore, using a coupled model is crucial for estimating the potential maximum risk of storm surges and waves in the coastal area of Qingdao.

Summary: The study found that the support vector regression (SVR) model performed well in rainfall-runoff simulation, even with short-term or single typhoon event data, estimating the rainfall-runoff relationship effectively. In contrast, the physically based hydrologic model (HEC-HMS) required more parameter optimization to achieve the performance level of the SVR model.

Summary: Coastal erosion is a major natural hazard along the northeastern shoreline (i.e., Yilan County) of Taiwan, with erosion and accretion occurring at different parts due to jetty and groin construction. Topographic and bathymetric surveys conducted in 2006, 2012, 2013, and 2019 reveal that erosion is significant in the northern Jhuan River estuary while accretion is inevitable in the northern Lanyang River estuary. The bathymetric surveys also suggest that the shoreline of Yilan County tends to accrete in summer but erode in winter, with approximately 2 km of coastline impacted by estuarine sediment transport along the Lanyang River estuary.

Summary: In September 2016, three consecutive typhoons, Meranti, Malakas, and Megi, caused extreme waves in eastern Taiwanese waters. This study investigated the impact of model grid resolution and wave-wave interaction on simulating typhoon-driven waves using the WAVEWATCH III (WW3) model. The results showed that the WW3 model with a grid resolution of 0.10 deg and the Climate Forecast System version 2 (CFSv2) winds yielded the most accurate simulations of typhoon waves. Excluding nonlinear wave-wave interactions led to significant underestimations of typhoon waves, particularly at higher grid resolutions. Additionally, the WW3 model outperformed the Wind Wave Model III (WWM-III) in accurately simulating extreme waves during the studied typhoon events.

Summary: In this study, the interaction between a solitary wave and a bottom-mounted, submerged elastic plate was numerically investigated. The effects of plate height, plate thickness, and the Young's modulus of plate material on the hydrodynamics were studied using a fluid structure interaction solver, a turbulence closure model, and a volume of fluid approach. The plate displacement was calculated using the Euler-Bernoulli beam theory. The wave nonlinearity and plate material properties were found to have significant effects on wave reflection, transmission, and dissipation.

Summary: This study aimed to verify the feasibility of amide proton transfer (APT) imaging in risk stratification of abdominal neuroblastoma (NB) in children, and compare it with the serum neuron-specific enolase (NSE). The results showed that APT values were significantly higher in high-risk NB than in the non-high-risk group, while there was no significant difference in NSE levels between the two groups. APT imaging has promising potential for distinguishing high-risk NB from non-high-risk NB in routine clinical applications.
