Summary: Coastal erosion is a growing problem along coastlines worldwide. This research focuses on two beaches in Benidorm, Spain - Poniente Beach and Levante Beach. Through the analysis of aerial images, studies on waves and storms, and sedimentological analysis, it was found that Poniente Beach's eastern zone experienced higher rates of erosion compared to the western zone. However, a change in wave regime caused this erosion trend to disappear in the last observed period. In contrast, Levante Beach had lower erosion rates due to reduced wave intensity. Furthermore, significant differences were observed in sediment grain sizes and wear behavior between the two beaches. This knowledge provides valuable insights for future beach management.

Summary: Understanding the time scales of beach response to extreme storms is crucial for coastal land management and risk assessment. This study investigates the disruption of beach stability and the subsequent recovery process. The results suggest that beach disruption is caused by complete beach inundation and strong wave reflection, leading to major erosion. The recovery time scale depends on the fate of sediment during the storm event.

Summary: This paper presents a method for quantifying the benefits of beaches in reducing storm and long-term coastal flood risk. The method is important for cost-effective decision-making on climate change adaptation in coastal areas. It considers the dynamic interaction of storm erosion, long-term shoreline evolution, and flooding to quantify the flood protection benefits of beaches. The results show that considering erosion is crucial for accurate flood damage estimation and that maintaining present-day beach width can significantly reduce flood damage.

Summary: This study analyzed the seasonal variation of sedimentary reservoirs in sandy beaches at the insular margin of a tidal inlet in Brazil. By measuring sedimentary budgets and identifying coastal processes, it was found that the internal sector showed accretion while the intermediate and external sectors experienced erosion. Regional standards of ocean surface waves and wind were evaluated, showing a predominance of southeast winds and wave power with average peaks during the dry and rainy seasons. Sedimentary gain was observed between April and July 2018, with increased loss from September to December 2018.

Summary: Since the 1970s, sand has been dredged and deposited onto the beaches of La Magdalena in the Bay of Santander in order to increase their width. A recent project to prevent sand losses involved the construction of breakwaters, but the results showed that the solution has not stabilized the beach as predicted. Topographic data and field surveys were used to understand the evolution of the beach and propose sustainable solutions.

Summary: This study analyzes the coastal changes of an 8 km-long beach in Haikou Bay, China, to understand the potential effects of a mega offshore artificial island (MOAI) with a diameter of 2.3 km. The results show that the presence of the MOAI leads to accretion on the leeside beach and retreat on the adjacent beaches due to altered sediment transport patterns. The study highlights the differences in coastal change between MOAIs and small-scale offshore obstacles (SCOOs) and provides insights for coastal sediment management strategies.

Summary: The morphology of subduction margins near the coast is influenced by a combination of erosion from ocean waves and permanent tectonic deformation from plate convergence. The edge of continental shelves tends to be located above seismic coupling on the megathrust, with variable distances of coastlines farther inland. The interaction between wave erosion and permanent tectonic deformation plays a key role in determining the location of the shelf break and coastline position.

Summary: Laboratory wave flume experiments are often used in coastal engineering and physical oceanography to understand morphodynamic processes. This study compared beach profile evolution under erosive waves and increasing water levels in three different facilities, showing that distorted profiles can be suitable for comparison with a modified Dean number. The new scaling method showed good agreement between dimensionless profile shape, sediment transport, and morphodynamics parameters.

Summary: The study examined the application of dynamic cobble berm revetments in North Cove, WA, USA, finding that they exhibited dynamic stability and the ability to quickly reshape during a spring tidal cycle. Despite being effective in protecting sandy beaches and hinterlands, the revetments experienced volume reduction and localized cobble transport due to significant wave height and high water levels. Additionally, the behavior of cobble berm revetments was found to be influenced by variations in the cobble-sand matrix.

Summary: Ageing stock and extreme weather events pose a threat to the safety of infrastructure networks. Insufficient funding for infrastructure management hinders systematic inspections, potentially leading to unnoticed distress and catastrophic failures. Synthetic Aperture Radar Interferometry (InSAR) has been proven to accurately detect surface deformations of different assets, offering a cost-effective and near-real-time monitoring tool. However, the large amount of data provided by InSAR requires automated integration with infrastructure inventories. This paper presents a new methodology that automates the integration of InSAR measurements and Geographic Information System-infrastructure inventories to detect potential warnings in extensive transport networks.

Summary: Top-down surface mixers are effective in preventing stratification, controlling cyanobacteria, and limiting sediment release of soluble manganese in drinking water reservoirs. However, their limited range of influence leaves a majority of the reservoir exposed to potential issues such as stratification, anoxia, and internal loading of inorganic nutrients and metals.
