Pond - what is this?

Very often, all over the world can meet many different bodies of water.Typically, they are formed in the depressions surface.So the question arises: "Reservoirs - what is this?What is the cause of their origin? "In order to answer them, it is necessary to get acquainted with this science as hydrology.It examines all the possible interaction of water with the environment, as well as the phenomena occurring in it.Some results hydrologists, used in navigation and combat operations on water flows.

Reservoir - a place where the liquid accumulates with minimal or no runoff.Often this place are the artificial and the natural basin.If we take into account the broad sense, the ponds are also called seas and oceans.


reservoirs Reservoirs are divided into several types according to various factors.In their lifetime they are divided into permanent and temporary.The latter arise only in certain seasons to a certain period of time.For example, pools and oxbow lakes, which appear as a result of spring floods of large rivers.As a method of forming ponds are man-made and natural.To include artificial pools, ponds, reservoirs, dams.

Waters - is water, differing from each other in their chemical composition, the content of trace elements and other biological substances.Also one of the important indicators is the accumulation of salts.It is on this factor determines the kinds of ponds.They are divided into fresh and salty.Each of them corresponds to a specific flora and fauna.


lake created by nature is an accumulation of water in the deepening of the land.It has no mouth, and the source, and is not any part of the world's oceans.The water is mostly stagnant, with no clearly defined flow.Power is mainly due to groundwater, less rain and snow.Lake - a particular body of water.This is due to the fact that sometimes it is it gives new life to the rivers, not letting them dry out.For its size and characteristics of the lake occupies a middle position between the pond and the sea.On the planet there are more than 5 million these reservoirs, which generally cover 1.8% of the land.

the largest lake in the world is the Caspian Sea.It does not flow, is located on the border of Asia and Europe.Water differs high content of salts, which ranges from 0.05% to 13% depending on the areas.


This accumulation of water - unstable phenomenon.As a rule, it formed during spring floods.Bayou located in the floodplain.She is constantly exposed to flooding.River, changing the direction of the bed, leaving a deep depression.Subsequently, they are the birthplace of the older women.Bayou is a full reservoir.It can be argued on its characteristics and the absence of flow.Often it is shaped like a sickle or a loop.Due to the fact that the waters of the river no longer flow into the oxbow lake, it is still some time there as a lake.Subsequently it is constantly logged sand and silt, and after a certain period of time, it turns into a damp meadow, marsh or completely dry.


often met pond - a pond.He created man in order to store water reserves, which will eventually be used to irrigate the land, sports, health needs, breeding of different species of fish, birds.They can often be found ciliates or copepods.It is most often breed carps, trout, carp and sturgeon.As a rule, the ponds are called reservoirs area exceeding 1 million m3.Earlier, near each village, which poorly equipped with water, there was a pond, often created by the people themselves.Power is due to rain, dirt, rarely river waters.Sometimes used to cleanse ponds near rivers ranging from various types of pollution.

in waters biological, physical and chemical processes are carried out in different ways.This is due to the characteristics of the respective types.
Unfortunately, the opinion that the river - a body of water, is erroneous.She - the water flow.The main difference lies in the fact that in all the watercourses there for, which, in turn, affects the formation of flora and fauna.
