12The Nile is usually said to be the longest river in the world, with a length of about 6,650km,[1] and the Amazon the second longest, with a length of at least 6,400km.[2] In recent decades debate has intensified over the true source and the placement of the mouth, and therefore the length, of the Amazon River.[3][4] Brazilian and Peruvian Studies in 2007 and 2008 added the waterway from the Amazon's southern outlet through tidal canals and the Pará estuary of the Tocantins and then concluded that the Amazon has a length of 6,992km and was longer than the Nile, whose length was calculated as 6,853km. The dispute is: "Is the channel south of Isla de Marajó to be treated as part of the Amazon, or as part of the Rio Tocantins?"[5]
A peer-reviewed article, published in 2009, states a length of 7,088km for the Nile and 6,575km for the Amazon, measured by using a combination of satellite image analysis and field investigations to the source regions.[6]
Therefore, as of 2018 the length of both rivers remains open to interpretation and continued debate.[2][7] Note that the disputed values have been put in parentheses.
