Summary: Coastal lagoons can attenuate extreme water levels compared to the open sea, but their protective property is expected to decrease due to sea-level rise. This study investigates the non-linear interactions between tides, storm surges, freshwater fluxes, and sea-level rise in idealized lagoons. The results show that maximum water levels inside lagoons can rise faster than sea-level rise due to non-linear attenuation changes, while for strongly choked lagoons, the maximum water levels rise slower than sea-level rise.

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: A numerical model is developed to simulate the compound flood scenarios of storm surge and sea level rise in Macao Peninsula. The results show that the flooding area caused by storm surges is mainly distributed in the west and northwest of the peninsula. In the worst-case scenario of 200-year-return-period storm surge and 1-meter sea level rise, the flooding area accounts for 41.1% of the land area, and the population at risk reaches 68.4% of the total population.

Summary: When local extreme water levels surpass defences, the consequences can be devastating. We assess the importance of sea-level rise and future weather pattern changes on UK coastal flood impacts. The study found that sea-level rise dominates future coastal risk and is highly linked to the future emission scenarios.

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: The study assesses the dependence between extreme skew-surge and extreme rainfall, as well as extreme skew-surge and extreme river-flow in New Zealand. The results show a significant but not strong correlation between these variables. Weather types play a crucial role in driving regional patterns of dependence.

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: As computational techniques advance, digital twins (DTs) are expanding their scope to include entire cities, oceans, or even the Earth. Digital twins of oceans provide comprehensive insights and predictions, enabling better-informed decision-making in ocean-related activities and management. In this study, a numerical model of the Seto Inland Sea (SIS) in Japan was built to establish a digital twin of the SIS. This model accurately simulated coastal and oceanic processes under extreme conditions, validated by observational datasets and successfully reproducing extreme storm surge events. By adding additional modules, this model will serve as the basis for constructing a digital twin of the SIS.

Summary: The study demonstrated a significant increasing trend in the Mangrove forests (MFs) of the Red River Delta over the past 30 years, with some areas being converted into aquaculture ponds. However, the mangroves continued to expand seaward to the northeast and southwest despite a drastic decline in fluvial sediment supply, as wave action and tidal dynamics played a role in sediment distribution behind barriers and along tidal channels. The conversion of MFs into aquaculture ponds by human activities led to substantial losses of MFs, but conservation policies implemented in later years helped alleviate these impacts.

Summary: Storm surges caused by tropical cyclones are a costly threat to coastal communities in southern China, and numerical surge models remain computationally challenging for probabilistic hazard assessments at regional scale. This study demonstrates the applicability of a simple 1D steady-state storm surge representation for regional hazard assessment without the need for additional empirical coefficients derived from observed data.

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: Storm surges pose a significant threat to coastal areas, especially developed deltas. Assessing the risk of storm surge on coastal infrastructures is crucial for economic development and disaster mitigation. This study calculated storm surge floods in the Yellow River Delta using various methods and found that the overall risk is relatively low, but coastal oilfields are at an increasing risk level. Wind directions can affect the extent of flooding, and storm events may cause erosion and decrease in inundation depths. Adaptation measures should be implemented based on local conditions, with a focus on constructing and maintaining seawalls on high-risk shorelines.

Summary: The study investigates the coupled effect of flood discharge and storm surge on extreme flood stages in the Pearl River Delta, showing that flood discharges dominate in the middle and upper delta while storm surges have the most impact near the river mouth. The results highlight the significant increase in storm surges and flood stages after 2002, emphasizing the threats posed by sea level rise and intensified storm surges in the lower Pearl River Delta. The findings are crucial for urban planning and flood control management in the region.
