裂流是一种发生在沿海地区的高速越岸流。它们是发生在沿着的最致命的自然灾害之一。在中国阳江海陵十里海滩，发生了多起溺水事故，其中大部分被调查与离岸流有关。为了调查该海滩的离岸流现象，于2021年8月7日至8月30日进行了为期24天的海滩观测。实地调查包括碎波带的波浪观测、水深测量、无人驾驶飞行器监测和沉积物取样。在调查过程中，海滩的状态依次从拦门沙转变为低潮阶地裂流和低潮沙坝/裂流，这是裂流发生概率较高的海滩类型。波高是控制海滩状态和离岸流发生的主要因素。X海滩模型的数值模拟结果与无人机拍摄的图像吻合较好，验证了该模型能够有效地表征不同海滩阶段的离岸流危害程度。研究结果可为十里海滩海滩开发管理和裂流预警提供参考。
Rip currents are a type of high-speed cross-shore current that occur in coastal areas. They are one of the deadliest natural hazard that occur along coasts. At Ten-Mile Beach on Hailing Island in Yangjiang, China, there have been a number of drowning accidents, most of which have been investigated to be related to rip currents. In order to investigate the rip current phenomenon at this beach, a 24-day beach observation was conducted from August 7 to August 30, 2021. This field investigation included wave observation in the surf zone, bathymetric measurements, unmanned aerial vehicle (UAV) monitoring, and sediment sampling. During the investigation, the beach state changed successively from barred to low tide terrace rip currents and low tide bar/rip, which are beach types with a high probability of rip current occurrence. Wave height was the main factor controlling the beach state and the occurrence of rip currents. The numerical simulation results of the XBeach model were in good agreement with images taken by UAV, confirming that the rip current hazard estimation model can effectively characterize the rip current hazard level for different beach stages. The results of the study provide a useful reference for beach development management and rip current warning at Ten-Mile Beach.
