It includes river systems over 1,000 kilometres ( 620 mi ). Contents 1 Definition of length 2 List of rivers longer than 1000 km 2.1 Notes 3 River systems that may have existed in the past 3.1 Amazon - Congo 3.2 West Siberian Glacial Lake drainage 3.3 Lobourg 4 See also 5 Notes and references 6 External links Definition of length 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 has long been disagreement as to whether the Nile or the Amazon is the world 's longest river. The Nile has traditionally been considered longer, but in recent years some Brazilian and Peruvian studies have suggested that the Amazon is longer by measuring the river plus the adjacent Pará estuary and the longest connecting tidal canal. Even when detailed maps are available, the length measurement is not always clear. A river may have multiple channels, or anabranches. The length may depend on whether the center or the edge of the river is measured. It may not be clear how to measure the length through a lake. Seasonal and annual changes may alter both rivers and lakes. Other factors that can change the length of a river include cycles of erosion and flooding, dams, levees, and channelization. In addition, the length of meanders can change significantly over time due to natural or artificial cutoffs, when a new channel cuts across a narrow strip of land, bypassing a large river bend. For example, due to 18 cutoffs created between 1766 and 1885 the length of the Mississippi River from Cairo, Illinois, to New Orleans, Louisiana, was reduced by 218 miles ( 351 km ). These points make it difficult, if not impossible, to get an accurate measurement of the length of a river. The varying accuracy and precision also makes it difficult to make length comparisons between different rivers without a degree of uncertainty.

( May 2017 ) This article or section possibly contains synthesis of material which does not verifiably mention or relate to the main topic. Relevant discussion may be found on the talk page. ( June 2009 ) One should take the aforementioned discussion into account when using the data in the following table. For most rivers, different sources provide conflicting information on the length of a river system. The information in different sources is between parentheses.

Flinders River 1,004 624 109,000 122 Gulf of Carpentaria Australia Notes When the length of a river is followed by an asterisk, it is an average of multiple information sources. If the difference in lengths between given information sources is significant, all lengths are listed. But if the lengths from secondary information sources are similar, they are averaged and that figure has an asterisk. Scientists debate whether the Amazon or the Nile is the longest river in the world. Traditionally, the Nile is considered longer, but recent information suggests that the Amazon may be longer. Differences in the recorded length of the Amazon mainly depend on whether or not it is valid to take a course south of the Ilha de Marajó at the Amazon 's mouth. New evidence, ( dated 16 June 2007 ) obtained from a high - altitude scientific venture in the Andes, claims that `` the Amazon is longer than the Nile by 100km, with its longest headwater being the Carhuasanta stream originating in the south of Peru on the Nevado Mismi mountain 's northern slopes and flowing into the Río Apurímac ''. However, the origin of the river at Nevado Mismi had already been known more than one decade earlier ( see Jacek Palkiewicz ), and satellite based measuring from this origin to the Amazon mouth has resulted in not more than 6,400 km. Generally, the most commonly used / anglicised name of the river is used. The name in a native language or alternate spelling may be shown. The Mississippi River just north of St. Louis. Saint Lawrence River along the New York - Quebec border. River systems that may have existed in the past Amazon - Congo The Amazon basin formerly drained westwards into the Pacific Ocean, until the Andes rose and reversed the drainage. The Congo basin is completely surrounded by high land, except for its long narrow exit valley past Kinshasa, including waterfalls around Manyanga. That gives the impression that most of the Congo basin was formerly on a much higher land level and that it was rejuvenated by much of its lower course being removed. Before Gondwanaland broke up due to continental drift, the Congo would likely have flowed into the Amazon. West siberian glacial lake drainage Main article : West Siberian Glacial Lake This river would have been about 10,000 km ( 6,200 mi ) long, in the last Ice Age. Its longest headwater was the Selenga river of Mongolia : it drained through ice - dammed lakes and the Aral Sea and the Caspian Sea to the Black Sea. Lobourg During the last glacial maximum, much of what is now the southern part of the North Sea was land, known to archaeologists as Doggerland. At this time, the Thames, the Meuse, the Scheldt, and the Rhine probably joined before flowing into the sea, in a system known by palaeogeographers as the Loubourg or Lobourg River System. There is some debate as to whether this river would have flowed southwest into what is now the English Channel, or flowed north, emerging into the North Sea close to modern Yorkshire. If the latter hypothesis is true, the Rhine would have attained a length of close to 1,650 kilometres ( 1,030 mi ). The former hypothesis would have produced a shorter river, some 1,400 kilometres ( 870 mi ) in length. Current scientific research favours the former opinion, with the Thames and Rhine meeting in a large lake, the outflow of which was close to the present - day Straits of Dover. See also Shortest river List of drainage basins by area List of rivers by discharge Notes and references Notes ^ Jump up to : The Nile is usually said to be the longest river in the world, with a length of about 6,650 km, and the Amazon the second longest, with a length of at least 6,400 km. In recent decades debate has intensified over the true source and therefore the length of the Amazon River. 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 6,992 km and was longer than the Nile, whose length was calculated as 6,853 km. However, as of 2010 the length of both rivers remains open to interpretation and continued debate.
