Rip currents form on beaches worldwide and pose a potential safety hazard for beach visitors. Therefore, effectively identifying rip from scenes providing real-time alerts to managers beachgoers is crucial. In this study, the YOLO-Rip model was proposed detect current targets based popular deep learning techniques. First, characteristics of large target size in images, neck region YOLOv5s streamlined. The 80 × feature map branches suitable detecting small were removed reduce number...
Among many coastal hazards, rip currents have gradually become one of the most noticeable hazards. Studies demonstrated that drowning accidents at beaches around world are related to currents. In this study, online and field questionnaires were combined for first time reveal beachgoers’ awareness in China from four aspects: demographic characteristics, swimming ability, information about visiting beaches, knowledge One educational strategy was introduced survey. The results suggest (i)...
The study of post-storm beach recovery is important for economic development and the protection life in coastal areas. In this study, field observations were conducted 21 days surf zone Dongdao Beach, Hailing Island, China, after tropical storm “Cempaka”. Data on depth, wave, Eulerian velocity, sediment, three-dimensional topography beach, high-frequency variations bed-level elevation collected. results showed that experienced medium- to low- medium-energy waves during covered two complete...
Abstract Coastal Trapped Waves (CTWs) have the potential to transmit significant energy from atmospheric wind systems, causing dramatic coastal changes over vast areas, even far systems. This study investigated impacts of CTWs generated by Typhoon In‐fa (2021) on northern South China Sea (NSCS) hydrodynamics using tide gauge observations, reanalysis data, and numerical model outputs. The analysis results indicate that induced exhibit distinct characteristics in different phases wave crest...
The DBSCAN algorithm can discover clusters of arbitrary shapes, but it has difficulty in predicting the appropriate clustering parameters. In this study, data field is introduced into number space, and relative mass (RM) calculation method proposed, first N points with larger dataset are calculated as initial by RM algorithm. Then optimized influence factor sigma used to calculate force range radius achieve optimization parameter, so select addition, study improves efficiency computing large...
