Summary: The analysis shows that beaches in large coastal cities are mainly the subject of sectorial studies, with little research on interactions between the city and the beach. There is a need to develop an integrated management model specific to beaches located in large cities.

Summary: Conventional views on saltwater intrusion are complicated by the existence of saltwater cells in the upper part of aquifers affected by tidal cycles. This study used time-lapse electrical resistivity imaging to evaluate the source of induced saltwater intrusion in a coastal sand aquifer. The results showed that dewatering occurred in the upper part of the aquifer near the pumping well, leading to the migration of saline water to the well. It suggests that future water resource development should focus on monitoring shallow pumping or pumping from deeper parts of the aquifer.

Summary: The Geostationary Littoral Imaging and Monitoring Radiometer (GLIMR) is a valuable tool for high temporal and spatial observation of coastal waters in the United States. Its unique geostationary viewpoint allows for improved quantification and reduction of uncertainty in tracking water quality events and oil spills. GLIMR's capabilities include the detection of harmful algal blooms and oil films, with different requirements for glint levels. The instrument also offers higher spatial resolution than existing satellites for oil spill surveillance, particularly in the Gulf of Mexico.

Summary: The coastal area at Riccione faces erosion processes exacerbated by climate change and is maintained through defense strategies, nourishment interventions, and experimental solutions. Ongoing monitoring efforts by the Arpae since 2000, as well as additional monitoring under the STIMARE research project from 2019-2021, aim to assess coastal behavior and the effectiveness of management actions. The study highlights the challenges in evaluating the effectiveness of interventions in combating erosion and the need for continued monitoring in this critical coastal setting.

Summary: Regular monitoring of coastal areas is crucial for mitigating erosive disasters. The erosion along Ghana's coastline, like other countries in the Gulf of Guinea, is a persistent issue. This study used multiple data collection methods, including drones, cameras, satellite images, and a dumpy level, to assess shoreline changes in Elmina Bay, Ghana. The results identified the causes and areas of erosion at a fine scale and highlighted the effectiveness of local video cameras and drones for monitoring shoreline changes. Satellite imagery, although a potential alternative, has limitations in temporal resolution for detecting daily or event-based beach changes.

Summary: Coastal urbanization and recovery of marine species have increased human interactions with marine wildlife, leading to conflicts such as the prolonged disagreement over beach use involving Pacific harbor seals at Children's Pool Beach in La Jolla, California. Factors influencing this conflict include personal values, differing perceptions of natural conditions at CPB, fear of change, and underlying inter-personal conflicts. Despite a decrease in overt conflict in recent years, disagreements over seal presence and legal issues persist, highlighting the importance of early and decisive conflict management by coastal managers.

Summary: This article proposes the implementation of an Index of Social and Morphological Vulnerability (ISMV) to show how the cost of services and morphological trends can affect the distribution of benefits, produce coastal narrowing, and consequently the resilience potential of coasts. The innovative indicator framework was carried out for the Mediterranean area of San Vincenzo in Italy, highlighting the importance of administrative actions in supporting or impoverishing the resilience potential.

Summary: This paper analyzes the development of the railway network in Sicily and its impacts on the coastal environment and tourism. The rails are mainly located in flat coastal areas, with minimal impacts on rocky and sandy coastal sectors. The study highlights the need for detailed research and monitoring programs to assess the railway network's impacts.

Summary: This study developed a methodology for sustainable beach management in response to the negative impacts of coastal tourism and climate change. It included SWOT analysis, BARE method for assessing beach quality, face-to-face interviews with beach visitors, and I-P analysis to identify key actions for improving beach management. The main issues that require management attention were found to be litter facilities, public facilities, and the use of renewable energy.

Summary: This paper reviews the behavior and status of Australian beach systems, predicting their response to future climate change impacts. While the 2021 IPCC AR6 report suggests a general recession of most Australian beaches by 2100, field data and satellite mapping indicate that 78% of Australia's beaches have been stable in the past few decades. The paper emphasizes the importance of studying and predicting beach behavior at a local level and suggests a sediment compartment approach for accurate predictions.

Summary: This study evaluates the use of PlanetScope cubesats for monitoring coastal change with high spatial and temporal resolution. A new toolkit called CoastSat.PlanetScope is introduced for shoreline mapping using PlanetScope imagery. The toolkit includes image coregistration, segmentation, thresholding, shoreline detection, and elevation correction. The study demonstrates an optimal shoreline accuracy of 3.5 meters for the tested coastline using specific indices and thresholding techniques. A generic elevation correction model considering tidal variability and wave setup is proposed. The study highlights the potential of using PlanetScope imagery for enhanced coastline mapping and its complementarity with existing approaches.

Summary: Floating pontoons play an important role in connecting land and sea, but there is limited data available to inform their design in terms of dynamic motion and the impact on public comfort and safety. This study conducted laboratory experiments on two types of piled floating pontoons, revealing that the motion response is dependent on the beam-to-wavelength ratio and the internal mass of the pontoon. The results showed that the interaction between the piles and the pontoon can lead to acceleration peaks more than six times the safe limit, as well as significant angles of rotation. These findings suggest that patrons standing on these pontoons may experience discomfort and instability.

Summary: Accurately mapping the changing underwater topography in wave-breaking areas is challenging but crucial for understanding sandy beach morphodynamics. Existing linear depth-inversion algorithms face theoretical and/or technical issues in the surf zone, limiting their accuracy. In this study, we propose a new depth-inversion approach based on Boussinesq theory, which quantifies nonlinear dispersion effects in nearshore waves. Experimental results show that this approach significantly improves accuracy in the surf zone, making it a promising method for practical applications using remote sensing technologies.

Summary: Analysis of satellite imagery covering over 8,300 km of sandy coastline reveals that the El Nino/Southern Oscillation drives coherent patterns of beach erosion and accretion around the Pacific Rim. Approximately one-third of all transects experience significant erosion during El Nino phases, while approximately one-quarter of all transects experience significant accretion during La Nina events.

Summary: Sandy beaches undergo constant reshaping by waves, tides, currents, and winds. The beach face, the area between land and ocean, is crucial for coastal processes such as wave energy dissipation and sediment exchange. However, datasets of beach-face slopes remain unavailable for most coastlines worldwide. This study introduces a new dataset for the Australian coastline, derived from remote sensing, which provides beach-face slope estimates and confidence measures. The dataset offers valuable information for predicting coastal hazards in Australia.
