most deepest point of the river bed, or other body of water, swirl or drilled passage, popularly called the whirlpool.What is a recess in the bottom relief represent?
Types whirlpool
The rotating water column can be seen in a wide variety of water bodies - on small rivers and in the open ocean.It is formed by the sudden expansion of the bed, in a collision for varying the temperature and velocity.Water, revolving in a small space, rushes to the outer edge of the circulation forming in the center of the notch.On the sea eddies occur in the collision counter-currents, tidal and tidal waves.The water in them can move with great speed.In the open ocean the size of the crater formed can reach several kilometers.
on the rotational speed of the river water is usually equal to the rate of its main stream.Vodoverti are typical for mountain rivers.They can form deep pits, which are called suvodi.Here, the rotation of the water in one direction for the breakwater, cape or other projection.Feed usually moves upward along the axis of rotation of the vortex.Usually, below the dam at the concave coasts steep bends occurs maelstrom.What is a natural phenomenon?This kind of whirlpool, where the water along the axis of a whirlwind for being sent down.
maelstrom
nature of their education due to the fact that the rate of flow throughout the river flow is rarely constant.It is accelerating, slowing down, sometimes almost disappears.Meet and backflow.On the part of the river called the rapids, it becomes very rough and fast.The reason for this phenomenon are increasingly narrowing shores, steep slopes.The rapid flow is accompanied by a kind of "boiling" water in the rapids.Such eddies washed out a hole in the bottom, forming a whirlpool.What is a dangerous place - everyone knows.No wonder the word "slough" is associated primarily with the words, tayaschimi in danger, "bottomless", "deep", "dark".
Quiet water so deep whirlpools
man caught in a difficult situation or a disaster, is often compared to a person who got into the maelstrom.What is a recess in the bottom of the reservoir topography better get round, even our ancestors knew.They believed such vodokrut often crushes everything in its path, tightening in your shed small vessels and ships.The old adage about whirlpools always used as a warning about the possible troubles.These are the places where and should be driven every evil.From these whirlpools stayed away, because you can not always predict where the water is a funnel capable of tightening at the bottom.It sank into the pool a lot of people, as mentioned earlier - dragged to the bottom of hell.
Eddies might not be of great danger, but they can not be underestimated.The calm water of the pit formed by them can be quite profound.In the shallows and oxbow frequent Still Waters.In the shallows, where the small, for the rapid and fast, and it is usually on a slow whirlpool.The saying and says "quiet water, whirlpools so deeply."
