The Biggest River In The World. The river has a length of 6650 km which makes it the longest river in the world. Besides being one of the LONGEST rivers in the world it also happens to be the WIDEST. While its estimated length of 4000 miles 6400 kilometers puts it under the Nile River that statistic. The biggest river in the world measured by the amount of water that flows down it is the Amazon.
Here is the list of 10 largest rivers in the world by discharge. In 2007 and 2008 some scientists claimed that the Amazon has a length of 6992 km and was longer than the Nile whose length was calculated as 6853 km. The main tributaries are White Nile and the Blue Nile which considered being the primary stream. The headwaters of Apurimac River on Nevado Mismi had been considered Amazonst most distant source until a study in 2014 found it to be the headwaters of Mantaro River in Peru. The 3449 miles long river has a discharge of 18040 m³ second with a drainage basin of nearly 2580000 square km. The largest river in the world is either the Amazon River or Nile River depending on how you measure it.
This is a list of rivers by their average discharge that is their water flow rateHere only those rivers are shown whose discharge is more than 2000 cubic metres per second 530000 US gals.

Measuring 1476 miles in length it is also the 15th-longest river in the world. So lets begin our countdown. Amazon River is the largest river in the world by discharge this is the volume of water moving down a stream per unit of time and the second longest river by length. This African wonder travels through eleven countries which include Ethiopia Eretria Sudan Uganda Tanzania Kenya Rwanda Burundi Egypt Congo and South Sudan.
