Today we are discussing an important topic Rivers and its tributaries. This is a very important topic that is asked in defence exams as every year many questions are asked from this topic. We are also giving a PDF of the same for the sake of your convenience. 


The river is the biggest source of water. Rivers provide us water to drink, irrigation, electricity, cook, clean things and easy & cheap transportation.  It is also a source of fresh water that flows naturally towards an ocean, lake, sea or another river. Rivers flow in channels. The bottom of the channel is called the bed and sides of the channel are called the banks. Sometimes a river flows into the ground and becomes dry at the end of its course without reaching another body of water.

Rivers begin at their source in the higher ground such as mountains or hills, where rainwater or melting snow collects and forms tiny streams. When one stream meets another and they merge together, the smaller steam is known as a tributary. It takes many tributary streams to form a river.

As a river flows, it carries along material or debris, called its load. A river’s load includes rocks, stones, and other large particles, which are washed along the river bed.  Finer particles float in the water. A river grows larger as it collects water from more tributaries along its course. The river ends at a mouth. In larger rivers, there is often also a wider floodplain shaped by flood waters over-topping the channel. Floodplains may be very wide in relation to the size of the river channel.
