摘要:

离岸流是垂直于海岸线、向外海方向快速移动的强劲海流。对于海边的人员来说非常危险,没有经验的游泳者一旦被离岸流带离浅滩,很难与之对抗游回岸边,往往因力竭而溺水。每年海滨区域都有大量的溺亡事件与此相关,但有关离岸流的知识在公众的视野里仍比较缺乏。本文从流体力学的角度对离岸流的危害、形成、特征以及分类进行了简要介绍,并在如何防范离岸流、保障自身安全等方面给出了一些建议。

Abstract:

The rip current is a strong current, perpendicular to the coastline and towards the open seas. It is very dangerous for people at the beach, and once carried away from the shoal by the rip current, inexperienced swimmers will find it difficult to swim back to the shore and will eventually be drowned due to the exhaustion. Most drowning accidents in the coastal area are associated with the rip current. The lack of public awareness about the rip current is one important cause. This paper reviews the damage, the development, the characteristics and the classification of the rip current from the perspective of hydrodynamics, and some suggestions are made of how to prevent the rip current and ensure the safety.

Key words: rip current, formation mechanism of rip current, beach safety, prevention strategy
