The river is a large stream of water. The river rises generally from a mountain or lake in a tableland. At first several very narrow streams of water join together and form one larger stream. This stream gradually widens in its course. On its way, it is joined by other smaller rivers. They are called its tributaries. At last the river falls into a sea, lake or another river. The mouth of the river becomes very wide. A river generally receives its water by the melting of snow on mountains. Sometimes it is fed by rain.The river is of great use to us. It helps us in many ways. It flows through many places. It makes them fertile. Prosperous cities are all situated on the banks of rivers. Ancient civilizations flourished in some river valleys. The river is of great help to farmers. In some countries, there are many rivers. Crops grow there in plenty. So famine is very rare there. Irrigation is possible easily where there is a river. Irrigation helps agriculture.It is true that rivers sometimes do us great harm. Still a river is a blessing to us. It helps us in many ways. So it is the duty of the Government to see that the rivers are not dried up. Our Government is now trying to control some rivers. We have read of many river valley projects which have been set up by our Government. Dams have been made there to store the water of these rivers. It prevents flood and helps agriculture and the generation of electricity. Sometimes these dams also cause flood when water is released from them in a huge quantity.
