Many people like to swim in the sea and feel as good as possible. But many do not know how easy it is to drown if you enjoy the beach. Most of us assume that alcohol is the culprit when such tragedies occur. However, most often without any other cause – strong currents.
In this article, we will tell you why this phenomenon is so dangerous, as well as the fate of those who do not know it before it is too late to avoid.
A riptide is one of the most dangerous natural phenomena that can be found in the sea. These currents kill regular and professional swimmers. This is often the result of a person simply does not know what to do when they find them.
You can try to carry the current, but it will not work. And when you know that this is the case, it is a panic – and will not help.
Rip currents are particularly dangerous when they occur in shallow water, where there is a gentle slope, low-lying coast, surrounded by sandbars or islets (for example, the Gulf of Mexico or the Sea of Azov ). In such cases, the body of the water are not able to return to the sea at low tide because of these natural barriers. The pressure which is placed at the point where the water flow is connected to the sea, is growing strongly. Rapids are formed by water that returns to the direction of the sea at about 2.5 to 3 meters per second, and forms a kind of river.
So it seems. The following diagram shows the reverse flow of moving water perpendicular to the coast in the direction of the sea:
These water corridors can occur everywhere along the beach. Waves roll each in the series, bringing the water more and more and go at different speeds to the sea, forming a reverse flow – namely the similar phenomenon area mentioned above:
In the next picture, you can clearly see the reverse flow of water, and some unhappy people who are caught in it:
In general, return currents are narrow – only 2-3 meters, and move at a speed of about 4-5 km per hour. These are not particularly dangerous. However, they can be up to 50 meters wide and 200-400 meters long and reaches a speed of 15 kilometers per hour.
As you can see and avoid getting caught in these currents? Look for the following signs:
- A rapidly flowing water channel, the right angle moves to the coast.
- The water in the area around the beach or the coast is of a different color (there is a white area surrounded by green or light blue).
- A range of moss, marine vegetation and constantly blowing flows into the open sea.
- 5-10 meters long empty in a range of other compact that flows into the waves.
If you see things described above, you are in luck, because that means that he recognized the Rip-flow before they have a chance to catch up in it. Do not go swimming there. But if you’ve seen one of these four characters? The bad news, since 80% of the dangerous surf currents can not be identified by sight.
Remember, diet currents can occur everywhere along the coast. If you are standing in water only the size, and certainly if you are in the chest, a riptide can take and will take to the sea. Of course, people who do not know how to swim, do exactly exactly – who simply love , Stay in one place. So in no case should you go into the sea away from other people, and of course always placed on the red flags and warning signs along the beach.
What to do if you get caught in a rip current
- Don’t panic!
If we are in a state of panic, our actions are determined by our self-preservation, and is much more difficult to make rational decisions. If you really know what to do if taken in a riptide, it has every chance of survival.
- Save your strength!
Not fight, back to the swim against the current when trying to shore. Unfortunately, so nothing to use all its energy is achieved. Rather than swimming to the shore, swim parallel. If the rip current is small (up to 5 meters), you can escape very quickly.
- If the rip current is wide (20 metres or more), what should I do?
It will not be easy to escape in this case, even if the rules are respected and swim parallel to the coast. But again, if you realize they do not leave, do not panic! Relax, because the flow of water will not last long; Stop in about 5 minutes once you stop, you can swim around 50-100 meters parallel to the coast and then go. If you try to go immediately, there is always the possibility that the flow will start again, and you are stuck again.
Important things to remember
- A rip current will never drag you under
The hangovers are not the same as the whirlpools. Drawing on the surface of the water, not on the seabed.
- The width of a rip current is always limited
Usually they are never more than 50 meters wide. More often than not, no more than 10-20 meters. Once you have swam only 20-30 meters from the shore, then you should be able to feel that you are safe in it.
- The length of a rip current is always limited
The flow of water is always weakening fairly quickly and ends at the point where the waves reach their apogee and begin to fall. Surfers call this area “Line Up”; Usually, no more than 100 yards from the coast.
Tell your friends about everything. So I could not only save his own life, but also to someone else.
