This natural phenomenon takes hundreds of lives a year. Severity rolls!
Sometimes in the news talk about cases where people drowned near the shore. Hearing this, most people only shake his head indulgently, thinking that this could happen to anyone who bathes in a state of intoxication. In part they are right, it really can happen to anyone. Only here the alcohol is not a factor, and the reason is quite different.
Most often, these accidents are due to the so-called rip current. This is a dangerous phenomenon, which is known to only a few. Sometimes the flow is called "basals" or "ripami." They were seen in all corners of our planet. Even if you are a first-class swimmer, but I never heard of such a phenomenon and do not know how to behave when there such a danger, then each of your vacation at sea - is the risk.
The first thing you need to know about rip current - is that they often occur near the shore, so they can tighten even one who stands up to his waist in water. Therefore, those who swim poorly, it is advisable to select only those beaches where there are lifeguards, and in any case not to swim alone.
Underlying these phenomena is normal physics. Sea or ocean currents, which are directed to the bank the right angle formed at a time when the tide is moving away from the shore back into the sea.
The most dangerous places are shallow seas with gently sloping beaches, which are surrounded by small islands, sandbanks and braids. In such places, the flow of water that is returned to the sea, prevent sand bars. At this point, the water pressure in the narrow strait is greatly increased. As a result, the stream is born, where the water flows very quickly.
Such corridors may occur at the coast in different places. This is especially true where there are regular tides. A man caught in the epicenter of the current, perplexed, because sailing all the time in one place. If the forces already on the wane, the flow drops it further away from the coast. Naturally, this situation is immediately causes panic, which can ruin a person's life.
The width of the flow is usually 2-3 meters, and the speed - 4-5 km / h. Such rips almost no danger to people.
But sometimes there are currents of up to 50 meters. Their length is from 200 to 400 meters. And the rate of flow of water up to 15 km / h! Once in such a flow, it is very difficult to get out.
In order not to fall into such a dangerous situation, it is necessary to pay attention to the phenomenon, in which you can find signs of rip current. The main feature - the visible part of the rips are always perpendicular to the shore. The difference in color can also help - usually such flows are lighter and a lot of seaweed and foam.
If a continuous strip of high tide there is a gap of 10 meters, be careful! Most likely, there is hidden rip current.
The biggest danger of these phenomena is that in most cases they do not manifest itself outwardly. Only professionals may identify such areas. In places where there are often rip current, put warning signs and red flags. These signals can not be ignored! If all the same you are not lucky enough to catch the wily rip you into a trap, do not panic. Act on the following algorithm:
1. Overcome panic. The man calmly assess the situation, has a much better chance to get out.
2. Take care of power. No need to spend it on something to row against the tide. Swim to the side, parallel to the beach. If the narrow rip you vyplyvesh from it very quickly.
3. assess the situation. Esly you swim away, but you can not get out of the flow, then it is widespread. Then you just need to calm down and stay on the water for 3-4 minutes. When the flow stops - Launch out into the 50 meters to the side and then back to the shore.
And remember, a rip can not drag you to the bottom! This trend brings with it tremendous speed only the top layer of water. Therefore, if you learned this information and not to get lost in an encounter with rip current, you can safely go on holiday.
This material is very useful to anyone who is going to rest on the sea. Share it with your friends.
