9:50 I propose that this dispute be settled by releasing a swarm of rubber duckies or other small floating object with beacons attached.

It seems pretty obvious to me that the distance through the lake should follow the low-point from the bottom of the tributary river to the mouth of the lake. I.E. if you drained the lake, what path would the river take?

[@piteoswaldo]

I think the line of highest flow should be the one used. Slightly harder to measure than in your definition, as you need to map the speed of the water at every depth. Also, his definition of which tributary to follow is completely wrong. At every junction, you should always follow the one with highest flow, the one which contributes most water to the river. Not the longest, to artificially inflate the length numbers.

[@alexjago51]

A line directly from the mouth of a tributary to the lake outflow isn't the direct equivalent of a line down the centre of the river. What I'm arguing for is to follow the path that the river would continue along if all the water in the lake suddenly disappeared.

The only way to be more accurate, IMO, would be to actually map the flow of the lake, and factor in flow volume of each tributary, and all of this changes with the season so it is a truly daunting question. But theoretically, if you could map all of the water molecules and determine it's sort of "predominant flow", that would be a solid basis for a final answer.

The source of the River Nile is lake victoria, Jinja to be precise. When you reach the point depth and the ripples from the underground are evident to show that it the source of the Nile.

[@jameswest4819]

The Orinoco is the longest, sometimes. That, apparently, depends on the tides. The Casiquiare River connects the Orinoco to the Amazon. Part of the time the Orinoco drains into the Amazon but also drains into the ocean. During High tide the Amazon drains into the Orinoco through the Casiquiare but also flows into the ocean once the tide changes. The Casiquiare is navigable so the route from the mouth of the Orinoco to the headwaters of the Amazon makes the Orinoco the longest, sometimes.

It's not about size, it's about your impact on the ecosystem.

[@PigZeee1]

Well then it’s amazon. Or the people that chop the trees down

[@henriquesoares2343]

Actually its the Nile because it is the sole source of water in the middle of the desert, making it surroundings the only arable land in hundreds of miles while the Amazon is one of many big rivers in the region, to the point that one of its tributaries has the fifth biggest volume of water of all the rivers in the world

[@PigZeee1]

Henrique Soares yeah sure Nile was the heart of a 9k year old civilization but the Amazon has 1/5 of the most types of animals and is getting cut down so a lot of the animals are dying

[@availabIe]

@@PigZeee1 That doesn't mean anything. The Nile has been, is and probably will still be more important for humans than the Amazon.

[@PigZeee1]

unavailable agreed but I never brought up humans. I think that the Amazon has a bigger impact on animals than the Nile

[@WyeExplorer]

That was super. I've walked every river of the Wye my humble local river in the UK and Wales and my brother and I always used to debate the sources of some of these and say that, in fact, it's the overall area with its streams and rivulets that forms the source of a river at its head. Who can say? I think it's down to the explorer that gets right up there. Mark

In Brazil, the country where most of the Amazon river is, the river is not called Amazon until much further downstream, near the city of Manaus. Only the Peruvians call the river Amazon since the meeting of the Ucayali and the Marañón

[@westhansen5735]

The names of rivers are irrelevant when discussing rivers and a single name is just picked for convenience. For instance the Missouri-Mississippi River is the longest river-system in the US, if you ignore the names, which you should. The idea is to measure flowing water. The longest flowing water course in the US is a combination of rivers and streams starting near Yellowstone National Park, regardless of what we call it.

[@revishon]

the reader of this sentence is worthy of love.

[@inari.28]

I’d say that whichever has the longest “pure river” (like the part of it commonly called the name) so without tributaries would be the longest.

[@whophonenewds4805]

I’d guess the Yangtze and then the Mississippi.

Again, often problematic. Hostorical variations, local custom, bias, all sorts of issues will affect the outcome.

It is debated if Indus valley was formed along the side of the Indus river or the now dead Saraswati river. Just so you know. According to Rigveda Saraswati river was a mighty river which flowed from the ghagra channel into the arabian sea. Hydrographic surveys also seem to indicate that along with many harappan cities found near the now dry river bed. So i think we kinda need to start calling the harappans, the Saraswati valley/river civilization.
