My goal is to create lists of rivers sorted by different characteristics of the rivers. As example, I am using the lists of countries, also sorted by different characteristics. I also want to add tables with these data to all rivers, containing information of ranking as well as the data themselves. Unresolved issue: should tribituaries be included?

The Nile article states that it in fact is the longest, I think it would be better if this list actually reflected the respective articles. Phoenix2 03:08, 20 Jun 2005 (UTC)
The article contradicts itself-- the body says that there is general agreement that the Amazon is the longest, but the caption for the Nile picture says that the Nile is the longest. Spikebrennan ( talk) 18:29, 22 February 2008 (UTC)
In response to Cburnett's edit summary, "Revert: *exactly* what looks off-center?", the central table listing the color key for the continents (which was the entire point of the exercise). Placing that table and the two images into a larger table, per your edit, creates three cells, and the central cell is centered. The problem, though, is that the continent table is still left-aligned within its cell; at high resolution, this becomes quite jarring. Compare its placement to the centered text immediately above it. The proper solution is to add centering to the continent table's style. -- Cryptic (talk) 00:30, 22 Jun 2005 (UTC)
This section should be a separate page, since the issues apply to rivers of any length, not just the longest. It's also just a list of questions with no answers beyond "it's hard/impossible". If it's hard, what's the solution? If it's impossible, what are the workarounds? Does the National Geographic or the like have a list and, if so, what methodology did they use?
According to the 1983 Edition of the Guinness Book of Records, the Nile-Amazon controversy does not refer to the vague general points in the section, but specifically to whether to include the Tocantins River estuary south of Marajó as part of the length of the Amazon. Most geographers say no, because the water flows from the Tocantins into the Amazon and not vice-versa. The "Some believe a fair statement is that the Nile is the longest in the world, while the Amazon is the strongest." comment suggests the dispute is motivated by chauvinism more than science.

"The Amazon basin formerly drained westwards into the Pacific Ocean, until the Andes rose and reversed the drainage." Is this so? I thought that the basin had drained into the (proto-)Carribean before the rising northernmost portion of the Andes blocked that route... I'm not 100% sure of that though.

According to the Louisanna University, the length is 5,564 km in length. According to The British Museum, it is approximately 5,560 km in length. Another physics paper titled "Simulation of irrigation effect on water cycle in Yellow River catchment" also cited the length to be about 5,464 km. The sources seems to concur that the length is about more than 5,000 km in length. -- Taken from Yellow River article discussion Horng Yih, Wong 01:05 11 July 2007 (UTC)
There are two versions of the length of yellow river, 4350 km and 5500 km. Majority of the sources I can find (including Encyclopaedia Britannica) put length of Yellow River to be 5464 km, which means 6th longest river. Shall we change the number to 5464 or at least put this different aspect under the Notes. Wang ty87916 00:31, 24 August 2006 (UTC)
I don't understand the section about "longest rivers that probably existed in the past." The title alone is a clue that there might be something wrong here. I am tempted to just remove it. Thoughts? -- Dmz5 04:11, 9 December 2006 (UTC)
Does a river literally evaporate in the dictionary sense of the word? I don't understand this reference. I understand the concept that the river does not reach a body of water, but what actually happens to said river?-- Dmz5 05:30, 9 December 2006 (UTC)
The lengths for the world's longest rivers differ considerbly in different Wikipedia articles. The longest rivers list in the River entry also differs from the List of rivers by length entry. AreDaval 02:58, 4 January 2007 (UTC)
According to the Britannica article, which is cited by Yangtze River, the Yangtze River is 6,300 km. This would place it ahead of Mississippi and tributaries. -- Voidvector 15:31, 17 June 2007 (UTC)
For the Niger, Parana, and Danube ( and others ), what are the percentages shown supposed to represent ? % of river length in the country ? Percentage of the drainage basin which each country covers ? Percentage of each country included in the drainage basin ? The numbers shown don't look correct for any of those. Does the Niger River go to Algeria ? Eregli bob ( talk) 18:12, 4 June 2008 (UTC)
I suggest that List of rivers by average discharge be merged into this article per WP:CFORK. Thoughts? -- Millbrooky ( talk) 22:07, 26 June 2008 (UTC)
Shouldn't Irtysh, as the world's longest tributary river, derserve a separate entry? 80.144.223.63 ( talk) 10:57, 28 August 2008 (UTC)
I think, it must be here. —Preceding unsigned comment added by 62.140.253.8 ( talk) 10:15, 10 September 2008 (UTC)
I'm going to remove the Synthesis tag - I don't see anything in the table that it applies to. I'll grant that the lack of attribution is a problem, but it all could be attributed if someone put in the effort to do so. Kmusser ( talk) 12:22, 23 May 2009 (UTC)

Since the last century, the lengths of the Nile and Amazon have been contesting for the title of the world’s longest river. From the lengths recorded in encyclopedias, textbooks, magazines and atlases with various languages, one could not recognise the longest river in the world. The Nile in Africa is reported to be anywhere from 5499 km to 6695 km with a maximum difference of 1196 km. And the Amazon in South America from 6275 km to 7025 km with a maximum difference of 750 km. These significant inconsistencies could be found in other great rivers, e.g. the Yangtze from 5550 km to 6397 km, the Mississippi from 5970 km to 6415 km, etc. (Hanks et al. 1979, Arthur et al. 1980, Rand McNally Encyclopaedia of World Rivers 1980, The Encyclopaedia of American (International Edition) 1980, McWillam 1995, National Geographic Society 2000, National Geographic World Atlas for Young Explorers 1998, O’Neill and Yamashita 1993, Osborne, Peissel 1997, Ondaatje 1998), The New Encyclopaedia Britannica (15th Edition) 1980, William and Levey (eds) 1975, Winchester 2000). It is impossible to distinguish which is correct (or more accurate) in a series of controversial lengths for each river. Therefore, recalculation of the lengths with high accuracy using modern technologies is highly desirable.

The following partial data for basin area (in 104 km2) and channel length (in km) is mainly from the article about TRIP. [2] TRIP is an automated estimator, so its figures are explicitly not reliable; but the paper lists other figures for comparison, which purport to be reliable but disagree with each other. The last column is from IJDE09, [1] which purports to derive more accurate figures from modern GIS data. Both these papers give a bit of info on "how river lengths are calculated".

If one compares the article with the version from May [1], two things are noticeable:
I understand that it's a lot of work to prettify a list like this, but I don't think it should be a reason to remove information. I would suggest to add the old information back in the old format even if it's ugly, and then gradually adapt it to the pretty format.
Missing rivers: the current list, which goes down to 2000 km, is missing several rivers that are over 2000 km and were in the old version, e.g. the Lower Tunguska or the Red River (Mississippi watershed). I am not sure what happened here.

Missing river: I believe the Australian River, Cooper Creek/Barcoo River with the tributaries Alice and Thompson Rivers should be added to the list of rivers greater than 1000 km in length. The overall length is approximately 1400 km. The Barcoo rises in Central Queensland, and flows to Lake Eyre. When it joins the Thompson River, it becomes Cooper Creek.

Missing river: I believe the Pitt/Sacramento River in California/Oregon should be added to the list of rivers greater than 1000km in length. There is an issue with what to do with delta/bay length, but ignoring that still leaves the length greater than 1100 km.

In List of rivers by length#Notes, the new information starting "New evidence" is queryable. The Daily Telegraph Monday 18 June 2007, page 18 says that
New evidence, (dated Saturday 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, and not from a place in the north of Peru as was thought before: this adds about 284 km = 176 miles to the length of the Amazon. |
But page 120 of my copy (published 1985) of the Times Atlas shows several tributaries of the Amazon draining all or nearly all of Apurímac Region, and the Apurimac river extending upstream even further to the south and originating on the Cordillera de Chilca in Arequipa Region. So it seems that the BBC or their sources got things wrong and this extended length is already in the older known length of the Amazon. Anthony Appleyard 06:33, 19 June 2007 (UTC)
Does anyone know how to contact the BBC correspondent who wrote the recent article, with a view to discovering exactly what data is being used? User:PeterGHughes 09:01 Wednesday 20 June 2007 (UTC)
The Nile river may not necessarily be considered the longest river in the world, provided with the new findings from the National Geographical Institute of Peru and the Brazilian Institute of Geography and Statistics. Through satellite imaging and measurements from various geographers, scientists have concluded that the origin of the Amazon River is directly situated at a peak called Nevado Mismi, in the snow covered Andes of Peru. The length of the Amazon is now recalculated at approximately 6,800 kilometers, which places it at the number 1 spot of being the worlds longest and largest river, in relations to the Nile which is at an estimated 6,695 kilometers in length.

I have just revised this entry for the second time to read Indian not Southern Ocean, for the simple reason that no authoritative source of geological or hydrological definitions supports the contention that any part of the Southern Ocean comes anywhere near the Australian coastline. At least 17 degrees of latitude at the nearest point separate them, and the mouth of the Murray is 24 degrees or some 2800kms from the northern limit of the Southern Ocean. All sources I have found agree that the Indian Ocean washes the shores of southern Australia at least as far east as the southern tip of Tasmania (some put it even further east). Colloquially in Australia however, all ocean to the south is referred to as The Southern Ocean (sometimes The Great Southern Ocean), but as this is only a local name which is at odds with international convention it seems inappropriate as a Wikipedia entry. I wish whoever keeps changing it back to Southern Ocean would do some research 80.101.60.126 ( talk) 14:07, 16 August 2009 (UTC). PeterHewlett 31 May 2008 —Preceding unsigned comment added by 144.139.63.161 ( talk) 12:39, 31 May 2008 (UTC)
There's no point in having a formal definition like that of the Indian Ocean if nobody uses it. The whole idea of classifying the oceans is to give a name to a general area of water. If that area winds and curls around various shapes, then it loses its usefulness. I don't think it's worth preserving this unused definition of Southern Australia being surrounded by the Indian Ocean. In all its uses that I've experienced (I'm not an oceanographer), the Indian Ocean is regarded to end at an imaginary line stretching South from Southern tip of Western Australia.
Can I suggest that the colour coding used to identify different continents in this list be reviewed? Colour coding per continent is a very good idea (I was specifically looking for European river lengths, for example), but the colours need to be much bolder. At present it is hard to differentiate between some of the shades, and for those with even mild red-green colourblindness (a not insignificant proportion of the population) the pale shades currently used are next to useless. -- Timothy Titus Talk To TT 16:39, 26 July 2008 (UTC)
I am trying to understand the explanation of how length is measured. It sounds like the article is saying that all the tributaries are added up. So, for example, if the river were Y-shaped we would add both branches and the trunk of the Y to get the length. Is that correct? This sounds like a very tricky and confusing way to do things. Is there a good essay or aticle on the topic? How can we identify and properly count every tributary and subtributary of a river? Can I find a list anywhere of rivers using the "longest tributary" method mentioned? Thank you very much! 67.247.4.200 ( talk) 01:47, 1 January 2010 (UTC)

Since I've seen editors swap the Nile and Amazon for 1st and 2nd rank a bunch of times recently--and there are fine sources for either case--I've taken the liberty of adding "note" footnotes for both, linked to a paragraph about the yet-unresolved debate over the lengths of both rivers and which is longer. I made sure to include at least four or five references to back up the statements made. Basically, the Nile has "traditionally" been said to be the longest, yet the Amazon's length was never very well known. In recent decades there's been a bunch of work on determining the "true source" of the Amazon--often resulting in the Amazon coming out as the longest in the world. The 2007-2008 study I linked actually determined the Nile was quite a bit longer than its normally said to be, but the Amazon was even longer. However it's clear that the issue is not resolved and there is no widespread general agreement about it (eg, one point someone mentioned was the use of the southern distributary of the Amazon at its mouth, increasing its length). I suspect the issue will become clearer in the years and decades ahead, and I personally suspect that the Amazon will turn out the longest. But while the matter is still debated and unresolved I figured our list ought to default to the traditional ranking of Nile first, then Amazon. I made sure to include the recently recalculated lengths for both in small numbers (per the text at the top of the table: "For most rivers, different sources provide conflicting information on the length of a river system. The information in different sources is between parentheses"). The "note" points out that the Nile's length is frequently given as "about 6,650 km" and the Amazon as "at least 6,400 km" (the Encyclopædia Britannica puts it this way). In short, the length of these two rivers has never been more than an estimate, as far as I can tell--especially the Amazon. For now the Nile seems longer, but as more evidence comes in that the Amazon is longer the Nile's long-held status as longest may fall. Time will tell. Hope this method of dealing with this works for people here. It's tiring to see the two rivers constantly being edited back and forth between #1 and #2. Pfly ( talk) 04:51, 5 August 2010 (UTC)
The Brazilian and Peruvian scientists claiming the Amazon being longer than the Nile made their conclusions possible by measuring the Amazon downstream to the beginning of the tidal estuary of Canal do Sul and then, after a sharp turn back, following tidal canals (furos) surrounding the isle of Marajó and finally including the marine Waters of the Río Pará bay in it's entire length. Studies about Sediments suggest that Río Pará is partly a remnant of a former Amazon distributary and partly a result of tectonic movements but not: a part of the recent Amazon. The measured route follows the waterway linking the Amazon with the port of Belém (only roughly, a big extra curve had to be added) leaving behind the common sense of what might be a river. Last and least, a little thing went wrong: their technique of measuring the Amazon makes the Mississippi the longest river, defining the Intracoastal Waterway to Houston as a part of it. -- WWasser ( talk) 23:07, 2 December 2010 (UTC)

REF: Length of the St-Lawrence river in the table.
Table says: 26. Saint Lawrence – Niagara – Detroit – Saint Clair – Saint Marys – Saint Louis 3,058 1,900 1,030,000 10,100 Gulf of Saint Lawrence Canada (52.1%), United States (47.9%)
A River starts at the Lake Ontario northern tip (Kingston / Wofe Island). Rivers connecting other great lakes are not the St-Lawrence river, ie: Niagara River.
B Canada (52.1%), United States (47.9%) - should read something more like: Canada (85%) US (15%) simply because the river is split between Canada and US from the Ontario Great Lake to Cornwall/Massena area, then is in Canada until it reaches the "Gulf of St Lawrence"
See wikipedia article: http://en.wikipedia.org/wiki/Saint_Lawrence_River "The St. Lawrence River originates at the outflow of Lake Ontario between Kingston, Ontario, on the north bank, Wolfe Island in mid-stream, and Cape Vincent, New York. From there, it passes Gananoque, Brockville, Morrisburg, Ogdensburg, Massena, Cornwall, Montreal, Trois-Rivières, and Quebec City before draining into the Gulf of St. Lawrence, one of the largest estuaries in the world. The estuary portion begins at the eastern tip of Île d'Orléans, just downstream from Quebec City.[2] The river becomes tidal in the vicinity of Quebec City.[4]"

It stands to reason that one should not be able to use the same stretch of river twice, for if we allow this then many of the first 90 rivers would be 1. amazon-ucayali-'little stream A' 2. amaxon-ucayali-little stream 'B' and so on for any little streams we can find amonngst the head-waters of the amazon.
I propose that the same watercourse (stretch of river) should not be used in two different entries. a glaring example of this is: 16.Tocantins–Araguaia and then 33. Araguaia where the Araguaia river has been used twice in two different entries. what stops us from finding small tributries of this and addding 34 .. 35 .. etc.

I would recommend removing the Amazon-Congo section of "River systems that may have existed in the past" until a citation has been provided. According to /info/en/?search=Congo_River#Natural_history the Congo formed 1.5m - 2m years ago. According to /info/en/?search=Gondwanaland Gondwana broke apart 180m years ago. If those dates are accurate, then the following sentence is untrue:
Before Gondwanaland broke up due to continental drift, the Congo would likely have flowed into the Amazon.
It's of course possible that the previous sentence merely needs a qualifier, ie something about the Congo basin, or whatever (I know nothing about river terminology). Either way, this fact needs a citation badly, and I recommend deleting it until it gets one. — Preceding unsigned comment added by Gweissman ( talk • contribs) 01:59, 21 April 2014 (UTC)

Please add "Wisła" after "Vistula". It is a river in Poland, and the Polish pronounce it as Wisła. 2600:387:0:80D:0:0:0:65 ( talk) 22:52, 17 February 2017 (UTC)

The Cauca River should be removed from the list since it is taking into account the lower reaches of the Magdalena River. This is redundant, as the Magdalena River is already measured through its lower reaches (and its total length is longer than the combined Magdalena-Cauca length). -- NoGhost ( talk) 18:41, 17 March 2017 (UTC)
The Nile? or rather as called on Wiki "the 2 Nile rivers", "the white Nile River Flows into the Blue Nile River", "The Nile leaves Lake Victoria"
So according to the Article Lake Victoria is part of ONE of the Nile Rivers? So they are 2 Rivers and not a single river! and should be measured separately! The lakes page says "Lakes can be contrasted with rivers or streams" So a lake is different than a River and not part of it! When you see a lake you dont call it a river! Thus making the 2 Nile Rivers even shorter.-- ArnoldHimmler ( talk) 23:50, 22 December 2017 (UTC)

It may be curious to add in the notes to the river table that "length of Vistula is affected by etno-political considerations as much as geography. In terms of river length alone distance from (Western) Bug spring (in Ukrainian Carpathians) to Vistula mouth is 1213 km (Source: Polish Wikipedia on 'Bug'), i.e. over 100km more than that from Vistula spring, possibly advancing it to 132 position in the table. On one hand, when they merge, 30km downstream from Warsaw, Vistula carries more water than Bug, on average. On the other hand, the naming convention may be also affected by the fact that Vistula conects the core historical provinces of Poland while Bug flows closer to the ethnic border between West and East Slavs (and historical Greater Lituania), so there was nobody to claim its importance. Western Bug belonging to Baltic catching area should not be confused with a different river Eastern Bug/Boh in Black Sea catching area. Exact name spelling for both rivers depends on Slav language in use."
Clarification: I propose to add my text above between " " signs in the Notes section of the list of rivers by length, with some editing, perhaps. I do not suggest change in the main table (in the Angara-Yenisiey style) because unsure how you define river length: by main stream (than present table entry is correct), or by the longest branch in the river catching area (aka Amazon length-than Bug-Vistula is more correct).

According to Ogooué River, it is 1200 km, thus qualifying. S Philbrick (Talk) 22:52, 5 February 2018 (UTC)
This list doesn't agree with the article it links to.
/info/en/?search=White_River_(Arkansas%E2%80%93Missouri) says that the white river is 1162 km.
This one says it's 1102 km. It looks like a typo or transcription error.
http://www.encyclopediaofarkansas.net/encyclopedia/entry-detail.aspx?entryID=2310 suggests it's 722 miles, which is 1162km — Preceding unsigned comment added by 212.187.165.98 ( talk) 16:25, 22 August 2018 (UTC)
I don't understand. Nile's length is 6,853, Amazon's length is 6,992, but Nile is still the first. Should it be edited or not? Andrey Tsyganov ( talk) 02:38, 15 January 2016 (UTC)
I like that the "officially recognized" lengths for Amazon and Nile are listed. The lengths are in dispute. One problem is that the new source of the Amazon (that would make it the longer river) is dry five months of the year ... but due to HUMAN intervention (a dam). This dispute makes the choice of "longest river" difficult. Kirin-rex ( talk) 05:45, 8 December 2016 (UTC) [1]
Can the wiki and English simple wiki please be aligned? General consensus is that the Nile is longer than Amazon (after the Amazons contentious source was debunked). — Preceding unsigned comment added by 193.108.73.47 ( talk) 13:59, 6 October 2017 (UTC)

Tanakorn Srichaisuphakit: I measured the longest source length because it seems unfair to measure a river if it begins at a confluence between 2 rivers.

Please mark both Nile and Amazon occupying both 1st and 2nd place due to uncertainity. 95.49.145.212 ( talk) 13:41, 3 June 2020 (UTC)
The following comment was moved from the redirect page to preserve it:
It is impossible to conclusively determine the order of the longest rivers, mainly for two reasons. The first is because rivers have a fractal property, which means that the more precise the measurement, the longer the river will appear. That means that if you have two maps, one undetailed map of a distant river and another precise and finely detailed map of a river you know very well, probably the latter will seem bigger on your measures. See here for more details.

Brahmaputra–Yarlung Tsangpo has incorrect number in "Length (miles)" column. It should be 2,466 miles instead of 24,466. Ma3oxuct ( talk) 18:18, 9 August 2020 (UTC)
In #135 as "Vistula-Bug", and in #180 as "Vistula". Having a look at how other rivers are represented, I think "Vistula" should be deleted from the list and the "Vistula-Bug" entry changed to "Vistula-Narew-Bug". And I think the correct drainage area should be 193.960 Km2. -- Noventamilcientoveinticinco ( talk) 21:48, 5 October 2020 (UTC)

My goal is to create lists of rivers sorted by different characteristics of the rivers. As example, I am using the lists of countries, also sorted by different characteristics. I also want to add tables with these data to all rivers, containing information of ranking as well as the data themselves. Unresolved issue: should tribituaries be included? Gerritholl 08:45, 23 Aug 2004 (UTC)
The Nile article states that it in fact is the longest, I think it would be better if this list actually reflected the respective articles. Phoenix2 03:08, 20 Jun 2005 (UTC)
The article contradicts itself-- the body says that there is general agreement that the Amazon is the longest, but the caption for the Nile picture says that the Nile is the longest. Spikebrennan ( talk) 18:29, 22 February 2008 (UTC)
In response to Cburnett's edit summary, "Revert: *exactly* what looks off-center?", the central table listing the color key for the continents (which was the entire point of the exercise). Placing that table and the two images into a larger table, per your edit, creates three cells, and the central cell is centered. The problem, though, is that the continent table is still left-aligned within its cell; at high resolution, this becomes quite jarring. Compare its placement to the centered text immediately above it. The proper solution is to add centering to the continent table's style. -- Cryptic (talk) 00:30, 22 Jun 2005 (UTC)
This section should be a separate page, since the issues apply to rivers of any length, not just the longest. It's also just a list of questions with no answers beyond "it's hard/impossible". If it's hard, what's the solution? If it's impossible, what are the workarounds? Does the National Geographic or the like have a list and, if so, what methodology did they use?
According to the 1983 Edition of the Guinness Book of Records, the Nile-Amazon controversy does not refer to the vague general points in the section, but specifically to whether to include the Tocantins River estuary south of Marajó as part of the length of the Amazon. Most geographers say no, because the water flows from the Tocantins into the Amazon and not vice-versa. The "Some believe a fair statement is that the Nile is the longest in the world, while the Amazon is the strongest." comment suggests the dispute is motivated by chauvinism more than science. Joestynes 4 July 2005 10:23 (UTC)
"The Amazon basin formerly drained westwards into the Pacific Ocean, until the Andes rose and reversed the drainage." Is this so? I thought that the basin had drained into the (proto-)Carribean before the rising northernmost portion of the Andes blocked that route... I'm not 100% sure of that though. Herostratus 01:06, 28 May 2006 (UTC)
According to the Louisanna University, the length is 5,564 km in length. According to The British Museum, it is approximately 5,560 km in length. Another physics paper titled "Simulation of irrigation effect on water cycle in Yellow River catchment" also cited the length to be about 5,464 km. The sources seems to concur that the length is about more than 5,000 km in length. -- Taken from Yellow River article discussion Horng Yih, Wong 01:05 11 July 2007 (UTC)
There are two versions of the length of yellow river, 4350 km and 5500 km. Majority of the sources I can find (including Encyclopaedia Britannica) put length of Yellow River to be 5464 km, which means 6th longest river. Shall we change the number to 5464 or at least put this different aspect under the Notes. Wang ty87916 00:31, 24 August 2006 (UTC)
I don't understand the section about "longest rivers that probably existed in the past." The title alone is a clue that there might be something wrong here. I am tempted to just remove it. Thoughts? -- Dmz5 04:11, 9 December 2006 (UTC)
Does a river literally evaporate in the dictionary sense of the word? I don't understand this reference. I understand the concept that the river does not reach a body of water, but what actually happens to said river?-- Dmz5 05:30, 9 December 2006 (UTC)

Since the last century, the lengths of the Nile and Amazon have been contesting for the title of the world’s longest river. From the lengths recorded in encyclopedias, textbooks, magazines and atlases with various languages, one could not recognise the longest river in the world. The Nile in Africa is reported to be anywhere from 5499 km to 6695 km with a maximum difference of 1196 km. And the Amazon in South America from 6275 km to 7025 km with a maximum difference of 750 km. These significant inconsistencies could be found in other great rivers, e.g. the Yangtze from 5550 km to 6397 km, the Mississippi from 5970 km to 6415 km, etc. (Hanks et al. 1979, Arthur et al. 1980, Rand McNally Encyclopaedia of World Rivers 1980, The Encyclopaedia of American (International Edition) 1980, McWillam 1995, National Geographic Society 2000, National Geographic World Atlas for Young Explorers 1998, O’Neill and Yamashita 1993, Osborne, Peissel 1997, Ondaatje 1998), The New Encyclopaedia Britannica (15th Edition) 1980, William and Levey (eds) 1975, Winchester 2000). It is impossible to distinguish which is correct (or more accurate) in a series of controversial lengths for each river. Therefore, recalculation of the lengths with high accuracy using modern technologies is highly desirable.

The following partial data for basin area (in 104 km2) and channel length (in km) is mainly from the article about TRIP. [2] TRIP is an automated estimator, so its figures are explicitly not reliable; but the paper lists other figures for comparison, which purport to be reliable but disagree with each other. The last column is from IJDE09, [1] which purports to derive more accurate figures from modern GIS data. Both these papers give a bit of info on "how river lengths are calculated".

If one compares the article with the version from May [1], two things are noticeable:
I understand that it's a lot of work to prettify a list like this, but I don't think it should be a reason to remove information. I would suggest to add the old information back in the old format even if it's ugly, and then gradually adapt it to the pretty format.
Missing rivers: the current list, which goes down to 2000 km, is missing several rivers that are over 2000 km and were in the old version, e.g. the Lower Tunguska or the Red River (Mississippi watershed). I am not sure what happened here.

Missing river: I believe the Australian River, Cooper Creek/Barcoo River with the tributaries Alice and Thompson Rivers should be added to the list of rivers greater than 1000 km in length. The overall length is approximately 1400 km. The Barcoo rises in Central Queensland, and flows to Lake Eyre. When it joins the Thompson River, it becomes Cooper Creek.

Missing river: I believe the Pitt/Sacramento River in California/Oregon should be added to the list of rivers greater than 1000km in length. There is an issue with what to do with delta/bay length, but ignoring that still leaves the length greater than 1100 km.

In List of rivers by length#Notes, the new information starting "New evidence" is queryable. The Daily Telegraph Monday 18 June 2007, page 18 says that
New evidence, (dated Saturday 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, and not from a place in the north of Peru as was thought before: this adds about 284 km = 176 miles to the length of the Amazon. |
But page 120 of my copy (published 1985) of the Times Atlas shows several tributaries of the Amazon draining all or nearly all of Apurímac Region, and the Apurimac river extending upstream even further to the south and originating on the Cordillera de Chilca in Arequipa Region. So it seems that the BBC or their sources got things wrong and this extended length is already in the older known length of the Amazon. Anthony Appleyard 06:33, 19 June 2007 (UTC)
Does anyone know how to contact the BBC correspondent who wrote the recent article, with a view to discovering exactly what data is being used? User:PeterGHughes 09:01 Wednesday 20 June 2007 (UTC)
The Nile river may not necessarily be considered the longest river in the world, provided with the new findings from the National Geographical Institute of Peru and the Brazilian Institute of Geography and Statistics. Through satellite imaging and measurements from various geographers, scientists have concluded that the origin of the Amazon River is directly situated at a peak called Nevado Mismi, in the snow covered Andes of Peru. The length of the Amazon is now recalculated at approximately 6,800 kilometers, which places it at the number 1 spot of being the worlds longest and largest river, in relations to the Nile which is at an estimated 6,695 kilometers in length.

I have just revised this entry for the second time to read Indian not Southern Ocean, for the simple reason that no authoritative source of geological or hydrological definitions supports the contention that any part of the Southern Ocean comes anywhere near the Australian coastline. At least 17 degrees of latitude at the nearest point separate them, and the mouth of the Murray is 24 degrees or some 2800kms from the northern limit of the Southern Ocean. All sources I have found agree that the Indian Ocean washes the shores of southern Australia at least as far east as the southern tip of Tasmania (some put it even further east). Colloquially in Australia however, all ocean to the south is referred to as The Southern Ocean (sometimes The Great Southern Ocean), but as this is only a local name which is at odds with international convention it seems inappropriate as a Wikipedia entry. I wish whoever keeps changing it back to Southern Ocean would do some research 80.101.60.126 ( talk) 14:07, 16 August 2009 (UTC). PeterHewlett 31 May 2008 —Preceding unsigned comment added by 144.139.63.161 ( talk) 12:39, 31 May 2008 (UTC)
There's no point in having a formal definition like that of the Indian Ocean if nobody uses it. The whole idea of classifying the oceans is to give a name to a general area of water. If that area winds and curls around various shapes, then it loses its usefulness. I don't think it's worth preserving this unused definition of Southern Australia being surrounded by the Indian Ocean. In all its uses that I've experienced (I'm not an oceanographer), the Indian Ocean is regarded to end at an imaginary line stretching South from Southern tip of Western Australia.
Can I suggest that the colour coding used to identify different continents in this list be reviewed? Colour coding per continent is a very good idea (I was specifically looking for European river lengths, for example), but the colours need to be much bolder. At present it is hard to differentiate between some of the shades, and for those with even mild red-green colourblindness (a not insignificant proportion of the population) the pale shades currently used are next to useless. -- Timothy Titus Talk To TT 16:39, 26 July 2008 (UTC)
I am trying to understand the explanation of how length is measured. It sounds like the article is saying that all the tributaries are added up. So, for example, if the river were Y-shaped we would add both branches and the trunk of the Y to get the length. Is that correct? This sounds like a very tricky and confusing way to do things. Is there a good essay or aticle on the topic? How can we identify and properly count every tributary and subtributary of a river? Can I find a list anywhere of rivers using the "longest tributary" method mentioned? Thank you very much! 67.247.4.200 ( talk) 01:47, 1 January 2010 (UTC)

Sometime back in april and may this year there were a series of edits and reverts mostly swapping the Nile and Amazon 1 and 2 ranking by lenth. In the process the drainage area figures got swapped between the two and now the list shows them both having the same drainage area, the Nile showing Amazon's figure. I'm gonna fix just this for now.

Since I've seen editors swap the Nile and Amazon for 1st and 2nd rank a bunch of times recently--and there are fine sources for either case--I've taken the liberty of adding "note" footnotes for both, linked to a paragraph about the yet-unresolved debate over the lengths of both rivers and which is longer. I made sure to include at least four or five references to back up the statements made. Basically, the Nile has "traditionally" been said to be the longest, yet the Amazon's length was never very well known. In recent decades there's been a bunch of work on determining the "true source" of the Amazon--often resulting in the Amazon coming out as the longest in the world. The 2007-2008 study I linked actually determined the Nile was quite a bit longer than its normally said to be, but the Amazon was even longer. However it's clear that the issue is not resolved and there is no widespread general agreement about it (eg, one point someone mentioned was the use of the southern distributary of the Amazon at its mouth, increasing its length). I suspect the issue will become clearer in the years and decades ahead, and I personally suspect that the Amazon will turn out the longest. But while the matter is still debated and unresolved I figured our list ought to default to the traditional ranking of Nile first, then Amazon. I made sure to include the recently recalculated lengths for both in small numbers (per the text at the top of the table: "For most rivers, different sources provide conflicting information on the length of a river system. The information in different sources is between parentheses"). The "note" points out that the Nile's length is frequently given as "about 6,650 km" and the Amazon as "at least 6,400 km" (the Encyclopædia Britannica puts it this way). In short, the length of these two rivers has never been more than an estimate, as far as I can tell--especially the Amazon. For now the Nile seems longer, but as more evidence comes in that the Amazon is longer the Nile's long-held status as longest may fall. Time will tell. Hope this method of dealing with this works for people here. It's tiring to see the two rivers constantly being edited back and forth between #1 and #2. Pfly ( talk) 04:51, 5 August 2010 (UTC)
The Brazilian and Peruvian scientists claiming the Amazon being longer than the Nile made their conclusions possible by measuring the Amazon downstream to the beginning of the tidal estuary of Canal do Sul and then, after a sharp turn back, following tidal canals (furos) surrounding the isle of Marajó and finally including the marine Waters of the Río Pará bay in it's entire length. Studies about Sediments suggest that Río Pará is partly a remnant of a former Amazon distributary and partly a result of tectonic movements but not: a part of the recent Amazon. The measured route follows the waterway linking the Amazon with the port of Belém (only roughly, a big extra curve had to be added) leaving behind the common sense of what might be a river. Last and least, a little thing went wrong: their technique of measuring the Amazon makes the Mississippi the longest river, defining the Intracoastal Waterway to Houston as a part of it. -- WWasser ( talk) 23:07, 2 December 2010 (UTC)

REF: Length of the St-Lawrence river in the table.
Table says: 26. Saint Lawrence – Niagara – Detroit – Saint Clair – Saint Marys – Saint Louis 3,058 1,900 1,030,000 10,100 Gulf of Saint Lawrence Canada (52.1%), United States (47.9%)
A River starts at the Lake Ontario northern tip (Kingston / Wofe Island). Rivers connecting other great lakes are not the St-Lawrence river, ie: Niagara River.
B Canada (52.1%), United States (47.9%) - should read something more like: Canada (85%) US (15%) simply because the river is split between Canada and US from the Ontario Great Lake to Cornwall/Massena area, then is in Canada until it reaches the "Gulf of St Lawrence"
See wikipedia article: http://en.wikipedia.org/wiki/Saint_Lawrence_River "The St. Lawrence River originates at the outflow of Lake Ontario between Kingston, Ontario, on the north bank, Wolfe Island in mid-stream, and Cape Vincent, New York. From there, it passes Gananoque, Brockville, Morrisburg, Ogdensburg, Massena, Cornwall, Montreal, Trois-Rivières, and Quebec City before draining into the Gulf of St. Lawrence, one of the largest estuaries in the world. The estuary portion begins at the eastern tip of Île d'Orléans, just downstream from Quebec City.[2] The river becomes tidal in the vicinity of Quebec City.[4]"

I note that the Darling River (Australia) is omitted from the list, other than as a tributary of the Murray. Yet in its own right it is 1,472km in length from furthest source to its confluence with the Murray. Other tributary rivers of the requisite length are included in the list, even though they form part of longer systems. The Darling should be added to the list.

The Kura River currently has the colour of a European river, it should have the colour of Asian rivers of course as it's situated on the Asian side of the Greater Caucasus. Kontribjutor ( talk) 09:24, 1 August 2013 (UTC)
It stands to reason that one should not be able to use the same stretch of river twice, for if we allow this then many of the first 90 rivers would be 1. amazon-ucayali-'little stream A' 2. amaxon-ucayali-little stream 'B' and so on for any little streams we can find amonngst the head-waters of the amazon.
I propose that the same watercourse (stretch of river) should not be used in two different entries. a glaring example of this is: 16.Tocantins–Araguaia and then 33. Araguaia where the Araguaia river has been used twice in two different entries. what stops us from finding small tributries of this and addding 34 .. 35 .. etc.
the ganges and brahmaputra are ok. they share a delta but are assigned different routes through it.

I would like to request change of the table itself. The Amazon river is not 6400km (3977 miles) but it is proved to be around 7062km (4388 miles) long from the source to the estuary - which is slightly more than Nile. My reliable source is Charles University (in Prague) professor Bohumír Jánský who was part of expedition called "Hatun Maya" in 1999 and afterwards in 2000. The expedition found the true source of the river. I'm a student and today I have been on his lecture where he was talking about Amazon river and especially about this expedition. I hope my request is made as it should be and that you will edit this mistake. Jorgepediator ( talk) 17:21, 9 January 2014 (UTC)

I would recommend removing the Amazon-Congo section of "River systems that may have existed in the past" until a citation has been provided. According to /info/en/?search=Congo_River#Natural_history the Congo formed 1.5m - 2m years ago. According to /info/en/?search=Gondwanaland Gondwana broke apart 180m years ago. If those dates are accurate, then the following sentence is untrue:
Before Gondwanaland broke up due to continental drift, the Congo would likely have flowed into the Amazon.
It's of course possible that the previous sentence merely needs a qualifier, ie something about the Congo basin, or whatever (I know nothing about river terminology). Either way, this fact needs a citation badly, and I recommend deleting it until it gets one. — Preceding unsigned comment added by Gweissman ( talk • contribs) 01:59, 21 April 2014 (UTC)

The Nile River is not necessarily considered the longest river in the world. Through satellite imaging and measurements from various geographers, they have concluded that the origin of the Amazon River is directly situated at a peak called Nevado Mismi, in the snow covered Andes of Peru. The length of the river is now recalculated at approximately 6,800 kilometers, which places it at the number 1 spot of being the worlds longest and largest river. == http://news.nationalgeographic.com/news/2007/06/070619-amazon-river.html == |

Has there been any analysis comparing "length" as defined by the total length of all of a river's tributaries? For example: the combined lengths of the Mississippi, Missouri, Ohio, Tennesee, Arkansas, Red, etc. Rivers as the length of that river. The idea that a river has one "true source" and only that "counts" seems a bit how-people-in-olden-days-thought. - Jason A. Quest ( talk) 14:28, 26 April 2015 (UTC)
I noticed that the Rio Grande (US and Mexico) is listed as about half in the US and about half in Mexico. About half is entirely in the US (Colorado and New Mexico), and the other about half forms a part of the border between the US (Texas) and Mexico. I believe that the border is near the middle of the river. [1] Should the border region be listed as forming a border rather than as in one country or the other? — Preceding unsigned comment added by John McLeod VII ( talk • contribs) 15:49, 20 October 2015 (UTC)

The information on this article is wrong for the Brahmaputra and Ganges rivers. It says the Brahmaputra is just one piece of the Ganges, and yet the Brahmaputra is longer than the Ganges.

The Cauca River should be removed from the list since it is taking into account the lower reaches of the Magdalena River. This is redundant, as the Magdalena River is already measured through its lower reaches (and its total length is longer than the combined Magdalena-Cauca length). -- NoGhost ( talk) 18:41, 17 March 2017 (UTC)
The Nile? or rather as called on Wiki "the 2 Nile rivers", "the white Nile River Flows into the Blue Nile River", "The Nile leaves Lake Victoria"
So according to the Article Lake Victoria is part of ONE of the Nile Rivers? So they are 2 Rivers and not a single river! and should be measured separately! The lakes page says "Lakes can be contrasted with rivers or streams" So a lake is different than a River and not part of it! When you see a lake you dont call it a river! Thus making the 2 Nile Rivers even shorter.-- ArnoldHimmler ( talk) 23:50, 22 December 2017 (UTC)

It may be curious to add in the notes to the river table that "length of Vistula is affected by etno-political considerations as much as geography. In terms of river length alone distance from (Western) Bug spring (in Ukrainian Carpathians) to Vistula mouth is 1213 km (Source: Polish Wikipedia on 'Bug'), i.e. over 100km more than that from Vistula spring, possibly advancing it to 132 position in the table. On one hand, when they merge, 30km downstream from Warsaw, Vistula carries more water than Bug, on average. On the other hand, the naming convention may be also affected by the fact that Vistula conects the core historical provinces of Poland while Bug flows closer to the ethnic border between West and East Slavs (and historical Greater Lituania), so there was nobody to claim its importance. Western Bug belonging to Baltic catching area should not be confused with a different river Eastern Bug/Boh in Black Sea catching area. Exact name spelling for both rivers depends on Slav language in use."
Clarification: I propose to add my text above between " " signs in the Notes section of the list of rivers by length, with some editing, perhaps. I do not suggest change in the main table (in the Angara-Yenisiey style) because unsure how you define river length: by main stream (than present table entry is correct), or by the longest branch in the river catching area (aka Amazon length-than Bug-Vistula is more correct).

I don't understand. Nile's length is 6,853, Amazon's length is 6,992, but Nile is still the first. Should it be edited or not? Andrey Tsyganov ( talk) 02:38, 15 January 2016 (UTC)
I like that the "officially recognized" lengths for Amazon and Nile are listed. The lengths are in dispute. One problem is that the new source of the Amazon (that would make it the longer river) is dry five months of the year ... but due to HUMAN intervention (a dam). This dispute makes the choice of "longest river" difficult. Kirin-rex ( talk) 05:45, 8 December 2016 (UTC) [1]
Can the wiki and English simple wiki please be aligned? General consensus is that the Nile is longer than Amazon (after the Amazons contentious source was debunked). — Preceding unsigned comment added by 193.108.73.47 ( talk) 13:59, 6 October 2017 (UTC)

The following comment was moved from the redirect page to preserve it:
It is impossible to conclusively determine the order of the longest rivers, mainly for two reasons. The first is because rivers have a fractal property, which means that the more precise the measurement, the longer the river will appear. That means that if you have two maps, one undetailed map of a distant river and another precise and finely detailed map of a river you know very well, probably the latter will seem bigger on your measures. See here for more details.
