Summary: Wetlands, such as tidal marshes and mangroves, provide valuable buffering capacity for reducing storm-induced flood and structural loss in coastal communities. However, sea-level rise, storms, and marsh loss may compromise the effectiveness of wetlands in the future. This study highlights the importance of coastal resiliency planning and marsh restoration in adapting to a changing climate.

Summary: The scientific community has made significant efforts in simulating flooding conditions, but the current models still lack accuracy and reliability. It is suggested to adopt an approach that considers various factors and enhance understanding of flood generating mechanisms. Developing innovative earth system modeling frameworks and conducting rigorous studies can provide opportunities to improve flood prediction and mapping.

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: There is a growing demand for coastal and marine restoration in the Caribbean to reduce flood risks. By using risk-industry methods, researchers find that restoring coral reefs and mangroves can generate a strong return on investment, even with high restoration costs. These findings provide valuable insights for identifying funding sources for these restoration projects.

Summary: Predicting mangrove wave attenuation is crucial for coastal flood protection, this study investigated the mechanical properties of five common mangrove species in the Pearl River Delta. Larger branch diameters result in higher mechanical strength, while larger leaf size leads to larger peak pulling forces. Species lower in the intertidal zone show stronger branches but more easily detachable leaves, potentially as a damage-avoiding strategy, with no clear effect of salinity on mangrove mechanical properties observed.

Summary: The study utilized flood risk vulnerability models to monitor storm impacts, assess flood risk due to hurricane storm surges and extra-tropical storms, model opportunities for mangrove restoration, and predict the benefits of mangrove restoration on vulnerable coastal communities. Results showed that mangroves were negatively impacted by hurricanes in 2017, but small-scale restoration initiatives can help reduce flood risk up to 475m inland. This work provides rationale for mangrove restoration in the Virgin Islands and can be used to inform coastal restoration and resilience-building activities in the wider Caribbean region.

Summary: The spatial variability in vegetation density controls sediment transport at sub-meter scales within a wave-exposed mangrove forest. Infragravity waves are likely drivers of sediment transport within the mangrove forest. Near-bed turbulent kinetic energy is correlated with bed level changes in both the mangrove forest and the unvegetated mudflat.

Summary: Shorelines respond to various drivers on different time-scales, with changes at longer time-scales often superimposed on shorter ones. A new approach using Complete Ensemble Empirical Mode Decomposition successfully predicted shoreline evolution from storm events to decadal timescales. By linking model drivers with shoreline position on multiple time-scales, the approach outperformed common shoreline models when using SLP and wave information. Prediction of shoreline changes over months, years, or decades remains a challenging task due to the complex interplay of different factors influencing beach dynamics.

Summary: The study reveals that wind plays a significant role in influencing velocity asymmetry in shallow tidal basins, with higher wind speeds leading to more extreme asymmetry patterns. Wind primarily affects mean and peak flow velocities in the basins, with limited impact on tidal harmonics. The depth-dependent velocity asymmetry patterns are most pronounced for wind speeds of 6 m/s and greater, and for wind directions parallel to the main axes of the basins' tidal channels.

Summary: Mangroves are increasingly recognized as a sustainable and cost-effective alternative for reducing coastal flood risk due to their functionality and persistence. However, the complex implementation of mangroves in flood risk reduction requires improving insights, advancing tools, and adopting an adaptive management approach to enhance their functionality and persistence. Further research efforts on quantifying the variability and uncertainty of mangrove functionality and persistence are necessary for successful integration into coastal flood risk management.

Summary: This study investigates the impact of mangrove extent on the Waikaraka Estuary in Tauranga Harbor, New Zealand, using in-situ observations and numerical modeling. The results show that fine sediment is unlikely to be flushed out of the estuary after mangrove removal and the hydrodynamics are mainly controlled by tidal interactions with bathymetry rather than the presence of mangrove vegetation.

Summary: This study aims to assess event-based and seasonal bed level dynamics for vegetation presence in natural and semi-natural salt marshes and to provide generic thresholds for vegetation presence. The study found that short-term bed level dynamics have a significant impact on vegetation presence, while seasonal dynamics do not have a clear threshold for vegetation presence. These findings are important for the management and restoration of salt marsh ecosystems.

Summary: The maximum seasonal depth of thaw in permafrost soils, known as the active layer depth, is influenced by various soil and atmospheric variables. Monitoring data from soil climate stations in the McMurdo Dry Valleys between 1999 and 2012 revealed significant variations in active layer depth and temperature at the top of the permafrost. However, there were no clear trends of increase or decrease during the period from 2000 to 2018. Wavelet analysis showed correlations between global and regional climate systems and de-seasonalized permafrost temperatures. Although the dataset is currently too short to draw conclusions about long-term changes, it serves as a valuable baseline for future assessments.

Summary: Tidal wetlands are popular for mitigating coastal storm impacts, but their effectiveness varies depending on the conditions and types of hazards. While they can attenuate short-period storm-induced waves effectively, they are less effective in mitigating long-period storm surges. Storm damage to vegetation, especially mangrove trees, can be significant and recovery may take years. Combined with other stressors, wetland persistence can be compromised, emphasizing the need for adaptive management strategies in nature-based coastal defense projects.

Summary: This research demonstrates how the effect of exposure to air on intertidal flat profile development in cohesive coastal environments can be incorporated into applied numerical modelling. The findings show that the stabilizing effect of exposure leads to a more flat-topped shape of intertidal mudflats, and higher air temperatures have a greater impact on bed level change.

Summary: The extent of flood protection provided by mangrove forests varies due to differences in tree growth characteristics and local geomorphology. A model experiment in Tauranga, New Zealand, showed that the distribution and channelization of vegetation have a greater impact on flood attenuation than vegetation density. Additionally, a forest with sloping topography reduces the rate at which long wave attenuation occurs.

Summary: This study examines the integration of salt marshes with traditional coastal protection structures as nature-based solutions (NbS) in the face of climate change and analyzes the combined impact of sea level rise and marsh-supporting management measures on vegetation establishment. The research identifies thresholds for vegetation establishment in terms of monthly inundation percentages and bed level changes and shows that the implementation of a brushwood dam can facilitate the establishment of vegetation further seaward. However, predicted sea level rise may cause vegetation retreat, which can be delayed by the presence and positioning of a protective structure.
