Tide rip意思

"Tide rip" is a term used in coastal geography and marine navigation to describe a strong current that forms at the mouth of a river or an inlet where the tide is flowing in or out. These currents can be particularly strong and hazardous to boats and swimmers due to the opposing forces of the tide and the river or inlet waters.

When the tide is flowing in, a tide rip can form as the incoming tide meets the outflow of a river or stream, creating a line of breaking waves. These waves can be dangerous for small boats, as they can capsize them or push them into shallower areas where they may run aground.

When the tide is flowing out, a tide rip can occur as the tide pulls the water from the river or inlet back out to sea, creating a strong outgoing current. This can be dangerous for swimmers and boats, as it can quickly carry them away from shore or into areas of stronger currents.

Tide rips are often visible on the surface of the water as lines of foam or turbulence, and they can be detected using tide charts and local knowledge of tidal patterns. Mariners and swimmers are advised to stay clear of tide rips and to be aware of the potential for strong currents when navigating or swimming in coastal areas.
