Summary: Based on an analysis of global coastal segments, it is estimated that about 3% of the coastline requires protection to prevent coastal migration and large-scale land loss. For the remaining 97% of coastlines, an estimated land loss of 60,000 to 415,000 square kilometers and coastal migration of 17 to 72 million people is projected.

Summary: A global concern for coastal ecosystems is the predicted rise in sea-level for which salt marshes must keep pace. Variables that control this elevation change need to be identified to predict the adaptability of marshes to future sea-level rise. Grazing by livestock can significantly reduce the annual rates of elevation gain and affect the future adaptability of salt marshes to grow vertically for rising sea levels. Trampling by grazing cattle, along with other factors like precipitation deficit and extreme drought, can lead to biocompaction and reduce the total elevation change.

Summary: In this study, a numerical model was used to investigate the impact of sea-level rise on biogeochemical processes in the York River Estuary. The results showed that sea-level rise amplified tidal range and increased flooding duration, leading to enhanced porewater exchanges and phytoplankton production in the shallow-water regions. However, there were relatively minimal changes in dissolved nitrogen under sea-level rise.

Summary: In response to sea level rise and escalating extreme events, coastal populations are developing diverse adaptation strategies to address local situations. These strategies include two main paradigms and different governance modalities associated with four archetypes. The study suggests the need for hybrid approaches, considering local conditions, and actively involving stakeholders to facilitate the development of social values and behaviors.

Summary: This study used the SLAMM model to assess the erosion, flood risk, and greenhouse gas sequestration resulting from sea-level rise in the coastal zone of Benin. The findings indicate an expansion of estuarine open water and open ocean, while inland open water, ocean beaches, and swamps are projected to decrease significantly. These changes have important implications for the ecological and economic well-being of the coastal area.

Summary: We provide the first global estimates of annual average exceedances of various flood levels under sea-level rise (SLR). Minor flooding will occur most days worldwide with a global SLR of 0.7 m, while moderate flooding occurs with the same frequency under 1.0 m SLR. The differences in flood thresholds, tidal ranges, and non-tidal variability among regions lead to variations in the SLR required for chronic flooding to occur. Our findings have implications for coastal flood hazard assessments and we have developed a framework called RAFFFTS to identify potential future tidal flooding hotspots using only 1-year observational records.

Summary: This study presents the first global estimates of annual average exceedances of minor, moderate, and major flood levels under sea-level rise. The findings demonstrate that chronic flooding can occur with less sea-level rise in areas with lower flood thresholds and smaller tidal ranges. The study also introduces a new assessment framework, RAFFFTS, which can identify potential future tidal flooding hotspots using only 1-year observational records.

Summary: The Earth's changing climate is causing ice sheets and glaciers to melt, leading to rising coastal hazards and sea levels. Coastal areas with a total population of over 300 million people, including 20 megacities, are among the most vulnerable to climate change impacts. Sea-level rise, combined with other factors, could lead to the displacement of hundreds of millions of people, with significant global impacts.

Summary: The sea level rise in the subtropical oceans between 35 degrees and 20 degrees S in the Southern Hemisphere is faster than the global average, mainly due to the persistent upward trend of the southern annular mode. Climate models have failed to reproduce this feature accurately, highlighting the need to reduce model biases for reliable regional sea level projections.

Summary: This study used the Tidal Marsh Model (TMM) and SCHISM to simulate changes in marsh systems in a subestuary of Chesapeake Bay under two scenarios of sea-level rise (SLR) over the next 50 years. The results showed that the sustainability of marshes is influenced by geomorphic settings and anthropogenic factors, with different rates of marsh decline observed under varying SLR scenarios.

Summary: This study aimed to measure the efficacy of removing Bacillus atrophaeus spores from a parking lot using spray-based washing methods and wash aids. The results showed that pressure washing was more effective than using a garden hose, with the first pass removing more spores than subsequent passes. Instant Ocean and Tween 20 wash aids were found to significantly increase spore removal when using a pressure washer, but the overall increase was only 1%-2% compared to tap water alone.

Summary: The asymmetry of wave climates affects delta avulsion behaviors and shape evolution. Increasing wave-climate asymmetry reduces the curvature of updrift delta flanks and increases the possibility of downdrift locations. However, under certain conditions, wave climates may inhibit downdrift avulsions.

Summary: Coastal flooding prevention measures, such as storm-surge barriers, are widely adopted globally due to rising sea levels. However, their effects on shallow tidal embayment morphodynamics are poorly understood. Field data and modeling results from the microtidal Venice Lagoon reveal that artificial reduction of water levels leads to increased sediment resuspension and decreased salt marsh accretion.

Summary: Tight interplays between physical and biotic processes in tidal salt marshes lead to self-organization of halophytic vegetation into recurrent zonation patterns developed across elevation gradients. Despite its importance for marsh ecomorphodynamics, the response of vegetation zonation to changing environmental forcings remains difficult to predict, mostly because of lacking long-term field observations of vegetation evolution in the face of changing rates of sea level rise and marsh vertical accretion.

Summary: Salt marshes are complex coastal systems where terrestrial groundwater, terrestrial surface water, and seawater mix. However, our understanding of water fluxes in these environments is limited due to the interactions between land and marine forcings. To improve our understanding, we used geochemical tracers and analytical models to investigate the water sources, flow directions, and velocities in salt marsh porewater. Our findings revealed seasonal recharge patterns and daily tidal cycles driving water dynamics in both deep and shallow subsurface environments. This understanding is crucial for studying biogeochemical cycles in salt marshes.

Summary: High-resolution convection-permitting models (CPMs) are crucial for estimating future short-duration extreme precipitation in mountainous regions. However, recent observational studies indicate that extreme hourly precipitation tends to decrease with elevation, which may be related to subgrid processes not fully simulated by CPMs. To evaluate the reliability of CPM projections, it is important to understand their ability to capture this reverse orographic effect.

Summary: Accurate estimation of the probability of extreme sea levels is crucial for assessing risk and designing coastal defense structures. This study compares different statistical approaches for estimating high quantiles and investigates the uncertainty associated with different calibration sample sizes. The results show that the metastatistical extreme-value distribution framework provides robust quantile estimates, especially with longer sample sizes. However, the optimal solution independent of the return period of interest remains elusive.
