Hai! ♥️ guys today we can see about world's main purpose water which was come from river,✨♥️ All of us love rivers so today we can know how rivers come.  
Rivers can form from springs, lakes, melting glaciers, runoff from rainwater, or any number of other ways.  Usually rivers are joined by other rivers.  Such rivers are called tributaries or tributaries.  Amount of water carried in a river.  A river is a combination of surface water and invisible underground water.  In rivers flowing through large valleys this component of invisible current may be much greater than the volume of visible water above.

Rivers that flow from their source to their basin usually flow into oceans or bodies of water such as large lakes.  In arid areas, river water reaches these levels through evaporation and dries up earlier.  Some rivers are absorbed into the ground through soil or through permeable rocks.  It remains as ground water.  Heavy abstraction of water for industrial and irrigation purposes can also see the river drying up before reaching its natural termination point.  The area that supplies water to a river or the land drained by a river is called a watershed or catchment area.Water in a river usually flows through its channel.  It is made up of a river bed between two banks.  Large rivers have flood plains outside this drainage area.  It is formed when river water flows out of the drainage area during floods.  Flood plains can be as large as river channels.

Mostly rivers flow in one way.  But some rivers are connected by many channels and form braided rivers.  Such large rivers are found only in some parts of the world, such as the South Island of New Zealand.  Braided rivers are located in erosion plains and some river estuaries.

A flowing river is a source of energy.  As a result, this current affects the channel of the river and changes its shape.  According to Brahm`s law, the mass of an object carried by a river is proportional to the sixth power of the velocity of the river.  Thus, when the velocity of the river is doubled, it has the power to carry 64 times more material.  In hilly hard rock zones, due to this, erosion channels are formed through hard rocks, and large rocks break down to form sand and small stones.  In the intervening parts of a river's course, when it flows on plains, bank erosion causes
