Summary: This study finds that the response of barrier-marsh-lagoon environments to sea-level rise is affected by human activities. The evolution of Long Beach Island in the past 182 years was significantly influenced by anthropogenic effects, especially during the 1920s-1950s.

Summary: The passage discusses the significance of overwash and washover deposits in sediment budgets for coastal barrier systems, and proposes a method for inferring volume from planform measurements using scaling relationships. It also highlights the importance of gaining three-dimensional insight into washover deposits from two-dimensional information.

Summary: Research shows that the characteristics of sediment deposits from geohazard events in built environments exhibit systematic similarities and differences compared to those in unbuilt environments. The built fabric in the environment exerts a fundamental control on the form of large deposits. Considering the influence of built fabric on the morphodynamics of flow-driven geohazards is a feasible step towards improving forecasts of hazard impacts and reducing disaster risks.

Summary: As sea levels rise, pressures on coastlines increase, leading to more retreat landwards; historically, barrier beaches have rolled back in response to various events, but little is known about the speed and extent of roll-back once management stops. Studying barrier roll-back at Medmerry, it is found that the process is progressing in the downdrift direction due to a decrease in cross-sectional area from longshore transport.

Summary: This study investigates the effects of overland flow and sediment transport forced across a barrier in the opposite direction during hurricanes. The findings show that sediment shifting seaward across the barrier is significant and has important implications for post-storm barrier recovery and evolution.

Summary: Hurricanes have serious impacts on human lives and infrastructure. A study on the geologic record of intense hurricanes in Southwest Florida reveals that at least three storms made significant impact on the region between 1920 and 1960. Despite a lack of significant storm surge in the past 60 years, it is important for the public to recognize that several hurricanes occurring between 1920 and 1960 produced storm surges greater than 10 feet.

Summary: As salt marshes migrate upland due to rising sea levels, they face challenges in the form of hazardous and contaminated sites (HCSs) that can release toxins if compromised. This study in Rhode Island, USA, inventoried HCSs and found that they are extensive along marsh migration corridors, especially in urban areas. This inventory provides important information for prioritizing and managing salt marshes in the face of accelerated sea level rise.

Summary: The study shows that discontinuous barrier retreat is prevalent when the storm return period and characteristic time scale of dune growth are of similar magnitudes. Under conditions of greater storm intensity, discontinuous retreat becomes the dominant behavior. Alternatively, higher rates of sea-level rise decrease the overall likelihood of discontinuous retreat in favor of continuous transgression.

Summary: A laboratory experiment using high-speed video image analysis was conducted to continuously measure the time and space evolution of overwash and beach profile under different wave conditions. The presence of an inflection point in dune geometry indicates a shifting turn in dune crest movement during overwash, with the overwash water volume reaching its maximum at this point. The study also found a linear relationship between overwash water volume and deposited sediment volume, and dune erosion volume proportional to wave energy flux. Secondary dunes were found to significantly alleviate coast erosion and reduce shoreline retreat, regardless of their height.

Summary: Dune height is a crucial factor in predicting storm impact, but dune width must also be considered. Low aspect ratio dunes lose less volume during storms compared to high aspect ratio dunes, and beach width significantly influences dune erosion. Wide beaches offer the best protection from erosion, while the width of the dune determines its longevity under persistent erosion.

Summary: This study used a 2D XBeach model to investigate the impact of extreme storms on undeveloped barrier islands, obtaining beachface water levels during the storm and pre- and post-storm elevation data. The research found that wave spectra and sediment grain size were crucial in simulating the extent of overwash.

Summary: This study successfully distinguished between marine and terrestrial sediment sources using XRF analysis and cluster analysis. The precision of clustering analysis provided a more accurate evaluation of sediment contributions from different sources. The technique shows promise for application in other coastal environments.

Summary: The use of UAVs in environmental applications, particularly in monitoring coastal areas with rapid morphological changes and high rates of sediment transport, has been proven to be cost-effective and easy to use. This paper presents three case studies showcasing the advantages of using UAVs for high resolution and accurate survey and monitoring, which include assessing coastal landforms and associated processes. The results demonstrate that the combination of quality drone-sensed data and precise topographic control enables quantitative estimates useful in assessing the impacts of natural processes involving both human and natural assets.

Summary: Salt marsh habitat loss and conversion in the marine-coastal district of New York are causing salt marshes to fall behind in keeping up with sea level rise. A study conducted in Long Island, NY found that vertical elevation growth within the rootzone is insufficient, leading to the need for optimizing conditions for native salt marsh plants and organic matter preservation. Understanding the full suite of processes contributing to elevation changes is crucial for managing this valuable resource for the future.
