Summary: This study utilized an unstructured-grid Finite Volume Community Ocean Model to simulate compound flooding in the Delaware Bay Estuary, investigating the impact of non-linear tide-surge-river interactions on water levels. The results indicated that tide-river interactions affect semidiurnal tides, while tide-surge interactions mainly influence diurnal tides. Increasing river flow rate shifts the transition zone of damping and enhancing effects downstream.

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: The study focuses on the adverse effects of climate change-induced storm surges and compound flood events on estuaries. Using the ADCIRC + SWAN coupled model, various scenario simulations based on Super Typhoon Hato were conducted to understand the nonlinear interactions between tide, surge, and river during extreme events. The results show that tide-surge phases, typhoon tracks and wind speeds, and upstream runoff all contribute to extreme water levels through different nonlinear interactions. The study emphasizes the dominant role of tide-surge phases and highlights the exacerbation of nonlinear effects with increasing typhoon wind speeds and upstream discharges.

Summary: Due to sea-level rise, the highest, lowest, and average water levels experienced by coastal communities in the United States no longer correspond to the official definitions of high tide, low tide, and mean sea level. Water levels now regularly exceed official high tide along certain parts of the Chesapeake Bay, Gulf Coast, and Puerto Rico, indicating a radical redefinition of the American shore caused by sea-level rise.

Summary: Many estuaries are damaged by material movements such as marine debris, suspended sediment, and pollutants. Understanding the estuarine circulation system is crucial for addressing these issues. This study applies a three-dimensional hydrodynamic model in the Yeomha Channel to investigate salt transport mechanisms. The model results are validated by comparing them with in-situ data, and the study identifies the dominant factors for salt transport patterns in different seasons. Long-term tidal constituents and tidal trapping effect are found to be unique characteristics contributing to material circulation in hypertidal estuaries.

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 examines the heatwave events in seven geographic subregions of China from 1979 to 2018 using the latest intensity-area-duration framework. The results show that heatwaves of all durations have increased in frequency and intensity, with shorter heatwaves increasing at a faster rate. Xinjiang and Southern China have the most frequent heatwave occurrence, while the Southwest and Southern China have the highest increase in heatwave frequency. In terms of spatial trends, Southern China, Xinjiang, and the Southwest have the highest rates of intensity growth, influence area, and duration respectively. The findings provide insights for developing strategies to prepare for and mitigate the adverse effects of heatwave occurrences.

Summary: Compound hot-dry events have the potential to overwhelm natural and human systems, leading to significant damages and socioeconomic tipping points. Climate change amplifies the impacts of these events, and their future risk and role are poorly understood. By the end of the 21st century, an additional 0.7-1.7 billion people will be exposed to compound events globally, with cropland exposure increasing by 2-5.7 million km(2). Countries with weak governance will experience a larger increase in risk compared to those with good governance, highlighting the importance of effective governance in managing and mitigating compound events.

Summary: In this paper, we conduct simulations to explore the potential evolution of the Indian Sundarbans mangroves under various scenarios of sea-level rise and consider the impacts of inundation and shoreline erosion. The results show significant mangrove decline in all cases, with greater losses as sea level rises. It is estimated that by the end of the century, the Indian Sundarbans mangroves could lose between 42% and 80% of their current area if current management practices continue.

Summary: Understanding wave transformation in marsh vegetation canopies is crucial for assessing nature-based shoreline strategies. This study investigates the challenges of accurately modeling wave dissipation in coastal marshes and proposes a new dimensionless parameter to represent the canopy drag coefficient (C-D). The study finds that uncertainties in vegetation measurements lead to variations in C-D expressions, and suggests using the Cauchy number (Ca) as the more appropriate parameter for larger waves.

Summary: Sandy-muddy transitional beaches (SMT-Beaches) are a type of coastal formation consisting of upper sandy beach and lower mudflat. This study examined the morphological characteristics of SMT-Beaches and the mechanisms of the formation of sandmud transition (SMT) boundary. Field surveys were conducted on SMT-Beaches in South China Coasts and a new equilibrium profile function for SMT-Beaches was developed. The function demonstrated good performance and improved accuracy compared to traditional methods. It was also found that sediment characteristics differ on both sides of the SMT boundary, with clay-to-silt grains increasing seaward.
