Talk:Amazon River

I suspect this sentence is misleading, but I want to be sure.

"In this journey, Orellana baptised some of the affluents of the Amazonas like Rio Negro, Napo and Jurua."

In my first reading of this, I took it to be an inelegant way to say that Orellana introduced some of the wealthy residents ("affluents") of the region to Christianity, including three specific regions. On my second reading I don't think this was intended. Does the following sentence capture what the author intended?

"In this journey, Orellana named some of the tributaries of the Amazon River such as the Rio Negro, Napo, and Jurua."

In the section Major Tributaries, a list of "some of the more notable ones" contains the Tocantins river, but the page of the Tocantins itself says that "it is not really a branch of the Amazon river, since its waters flow into the Atlantic Ocean alongside those of the Amazon".

It flows into the Rio Para, the southern branch of the Amazon delta. On this southern branch, 3% of the total flows through the Tajapuru and Breves canals to the Rio Para, into which the Tocantins flow. The Tocantins can thus be considered part of the Amazon water system. It is a tributary. In Brazil it is considered a separate water basin (Rio Para-Tocantins). While the length of the Amazon is measured on the South Branch to be considered the longest river in the world. It is a bit controversial. According to them, the Tocantins is a separate water system, but when it comes to the length of the Amazon, they already count with this southern branch. 2A02:AB88:4702:7900:FC6E:D1F2:AEA:13BA (talk) 18:11, 4 October 2024 (UTC) [reply ]

This mistake is only in the English version. In the Czech version it is correct.

The Amazon river is the longest in the world. In 1999 and 2000, the scientific team of prof. Bohumír Janský from the Faculty of Natural Sciences of Charles University found that the river was 7 062km long. Bohumír Janský even got a state award from Peru.

Please fix this mistake, thank you Lairdone (talk) 10:22, 3 October 2024 (UTC) [reply ]

It is calculated from the mouth of the Rio Para, which is 350 km longer than the main estuary. Also from the source of the Mantaro which added another 100 km to the total length. Only the Mantaro source is intermittent as opposed to the Apurimac's permanent source.

Localpatriotism around the length of rivers.

Actually, it is the volume of water flow that reflects the size of a river. Somehow everyone overlooks this fact. 2A02:AB88:4702:7900:FC6E:D1F2:AEA:13BA (talk) 18:24, 4 October 2024 (UTC) [reply ]

I am adding the research article of prof. Janský: https://www.researchgate.net/publication/294373863_A_New_Survey_of_Sources_of_the_Amazon

I think it's worth looking into. Lairdone (talk) 09:32, 12 January 2025 (UTC) [reply ]
