| 摘 要： | 裂流发生迅速,发生位置隐秘,发生范围相对较小,发生时海浪大、流速快,这些特点给裂流观测带来困难。本文以威海国际海水浴场为研究对象,通过水深地形测量、海浪海流观测及高空摄影等多种观测方式相结合,尝试采用可行且易于实现的方法对裂流易发区域进行定位,在此基础上对该海域裂流类型和产生原因进行分析,并进一步进行威海国际海水浴场裂流区划。研究表明:威海国际海水浴场水下地形较为复杂,离岸200 m范围内存在5个沙丘-沟槽结构,沟槽和东侧栈桥前沿是裂流危险区,分属海滩型裂流和边界型裂流,裂流流速在0.5~1 m/s之间,观测期间裂流平均风险等级为中等。本研究可为裂流观测和海水浴场管理提供一定的参考。

| Abstract: | It is difficult to observe the rip current because of its rapid occurrence,hidden location,small scale,large wave and fast velocity.Taking Weihai International Bathing Beach as the research object,we try to find one feasible and easy method to locate the areas of rip current by combing topographic survey,wave observation,current observation and aerial photography.On this basis,we analyze the types and causes of rip current,and further carry out the division of rip current in Weihai International Bathing Beach.It concludes that there are five sand dune-trench structures within 200 m offshore and the front edges of the trenches belong to beach type rip current.The east trestle is a dangerous area of rip current,which belongs to boundary type rip current.The rip current velocity is between 0.5~1 m·s-1,and the risk level is medium during the observation period.This study can provide some reference for the observation of rip current and the management of the bathing beach. |
