This is a list of the longest rivers on Earth. There are many factors, such as the source  , the identification or the definition of the mouth, and the scale of measurement  of the river length between source and mouth, that determine the precise meaning of "river length". As a result, the length measurements of many rivers are only approximations see also coastline paradox. In particular, there exists disagreement as to whether the Nile  or the Amazon  is the world's longest river. Even when detailed maps are available, the length measurement is not always clear.
Determining the world's longest river is not an easy task. Although The World's Longest Rivers By Length. 1. Nile River – 6, km. Although.

Determining the world's longest river is not an easy task. Although for most of us, the answer would be the Nile River , there is a section of scholars who regard the Amazon River as the true winner of this title. The difficulty in declaring a unanimous winner lies in the fact that the determination of the headwaters or the origin of a river is often quite challenging. Large rivers like the Nile and Amazon have numerous sources and many large and small tributaries. The need to find the furthest source of a river is there if the true length of the river has to be calculated. Often, such sources are located in remote and inaccessible locations, rendering the discovery of such sources an arduous task. However, with the discovery of newer sources of such rivers, the ranks might vary in the future.
The process is far more complicated than finding the source and the mouth then measuring the distance between them. Rivers often join together in river systems making it very difficult to pinpoint where an individual river begins and where it ends. Today, most hydrologists agree that the most accepted method is to measure the longest possible along-thalweg continuous distance from the headwaters of the 1st order stream to the mouth of a river. A 1st order stream is a stream without any tributaries entering. In other words, to find the longest river, you have to measure the length of the longest continuous river channel in a given river system. For instance, for most rivers, the mouth is easy to determine and measure, but for very large rivers like the Amazon, which flows into the ocean, placing the mouth can be less concrete — and can make all the difference in terms of river length.
There are many long rivers in the world, but which ones are the longest? Naturally, there is a disagreement over the answer to this question. While The Nile has traditionally been considered to be longest in the world, the Amazon has some pretty fierce defenders as well. The debate arises over the difficulty in determining the full extent of a river, and also because measurements differ according to who measured them. Another source of disagreement is the role played by tributaries, with some scientists arguing for their inclusion while others leave them out. Luckily, when determining length, several major rivers stand out from the crowd. Here are a few, and the reasons for why they made the list:.

Jump to navigation. Rivers have always been the place where the greatest civilizations flourished. They are the source of all what is needed from the mother nature. Amazon River of South America is the second longest river in the world with a length of 6, km. But it is by far the largest river by water flow with an average discharge greater than the next seven largest rivers combined. Flowing in China, Yangtze River is not only the third longest river in the world but also the longest river in Asia.
The Nile is credited as the longest river in the world. Its main source is Lake Victoria in east central Africa. From its farthest stream in Burundi, it extends 6, km 4, miles in length. The two longest rivers in the world are the Nile, flowing into the Mediterranean, and the Amazon, flowing into the South Atlantic. Which is the longer is more a matter of definition than simple measurement. The Amazon begins with snowbound lakes and brooks-the actual source has been named Laguna McIntyre-which converge to form the Apurimac. This joins other streams to become the Ene, the Tambo and then the Ucayali.
