List of the longest rivers on earth
The list of the longest rivers in the world contains the rivers longer than 1000 kilometers in descending order.
The list contains hydrographic and water-related geographical features, so, for example, the countries through which the river flows are not listed. It contains both main rivers (flowing into the sea or endorheic ) and tributaries .
The length specification generally refers to the longest flow path within the respective river system. Flow paths that deviate from this, e.g. along the main river by name, are marked in the Rank column with the same number and an additional letter. Sea bays that continue a listed river, such as Obbusen , Yenisei Bay or Río de la Plata are not taken into account.
Explanation
- Rank: Consecutive numbering of the streams flowing into the sea according to the longest flow path in the respective river system . (Usually, for example, the length of the Mississippi over the Missouri and its longest upper course is given.) The tributaries (with smaller numbers) are arranged hierarchically therein; after the number of the main river, separated by a point, the rank number (again according to length) follows under the respective tributaries. Large river systems even have tributaries of the fourth order that exceed 1000 km in length (example: 2.1.2.1 Río Madre de Dios). The sorting of this column creates a clear order according to river systems.
- Length: The length of the respective river or flow path in kilometers (km)
- Name: Name of the main river, followed or not by the names of the river sections or tributaries that make up the longest flow route
- Mean discharge : mean discharge (water flow) in the long-term mean in cubic meters per second (m³ / s) (applies to the area of the maximum size of the river, usually the mouth)
Note: The list is sortable. By clicking on a column header, the list is sorted according to this column, another click reverses the sorting. Any desired combination can be achieved by clicking two columns in a row.
Rivers with a length of at least 1000 km
Longest river on earth
The Nile was not always considered the longest river on earth. For a long time, the Blue Nile , with which it is around 4000 kilometers long, was considered the source river of the Nile and not the somewhat smaller, but much longer White Nile . The longest flow path in the river system of the White Nile via Luvironza, Ruvuvu and Akagera was only discovered in 1893 by the Austrians Oskar Baumann and Oskar Lenz .
In the older literature, up to around the end of 1970, the Mississippi with its tributary Missouri can also be found as the longest river on earth. There it was wrongly given as 6730 km or 6800 kilometers. In the literature, even after the first measurements after 1893, the Nile was initially only given as 6324 kilometers and the Amazon , measured over the main source river Marañón , as 6518 km. The longest flow path in the Amazon system was not found until 1971 in the headwaters of the much longer Ucayali , and the length specifications for the Amazon that had been valid up to that point had to be corrected accordingly. So it happened that within a few years, depending on the accuracy of the measurements and definition of the source river, the Nile was once the longest river, then the Mississippi with Missouri and also the Amazon.
Even today, the position of the Nile is not undisputed, depending on the definition of the course of the Amazon river . If you include the course of the river south of the river island Marajó , which lies in the mouth of the Amazon, across the bay of the Pará to the Atlantic, the Amazon comes to over 6,700 km in length. From a hydrological point of view, the Pará belongs to the Tocantins river basin .

- ↑ The total length of the Nile is often given as "approximately 6650 km" (Magdi M. El-Kammash, Harold Edwin Hurst , Charles Gordon Smith: Nile River. As of July 21, 2017, accessed August 2017), but depends among other things depending on the chosen measuring path (e.g. from the source areas or from the outflow of Lake Victoria), the information varies between 5499 km and 7088 km ( Shaochuang Liu, P Lu, D Liu, P Jin, W Wang: Pinpointing the sources and measuring the lengths of the principal rivers of the world .

- ↑ The total length of the Amazon is sometimes given as "at least 6400 km" (Alarich R. Schultz, Raymond E. Crist, James J. Parsons: Amazon River. As of May 25, 2017, accessed in July 2017), but depends among other things depending on the selected measuring path (e.g. in the area of the mouth along the main stream or on the longest possible route including sea bays), the information varies between 6275 km and 7025 km ( Shaochuang Liu, P Lu, D Liu, P Jin, W Wang: Pinpointing the sources and measuring the lengths of the principal rivers of the world . In: Int J Digital Earth. 2, March 1, 2009, pp 80-87.. doi : 10.1080 / 17538940902746082 . ). For details, see the article on the Amazon .
- ↑ Since the 1930s, measurements have no longer been made over the source river Marañón , which is richer in water , but from the source area of the much longer Ucayali. The exact source was not yet determined at the time, but was assumed from the beginning of the 1970s in the area of the Nevado Mismi glacier in southern Peru. In 2007, a Peruvian-Brazilian expedition confirmed the location of the farthest source in the Apacheta Gorge on Nevado Quehuisha (Kiwicha Mountain), a neighboring mountain of the Mismi, as proposed by Jacek Palkiewicz in 1996 (Günter Paul: The Amazon is longer than the Nile. In: FAZ , July 4, 2007, accessed July 2017). Depending on whether you measure the shortest stretch to the sea or the longest drainage route plus the Rio Pará bay, values between 6400 km and 7000 km result. According to cartographic measurements from 1969, the total length of the Amazon on the shortest river route was put at 6448 km. A measurement in the 1980s showed a value of 6,788 km (Dieter Engelmann: Amazonien. In: Planet Wissen , as of June 13, 2017, accessed in August 2017). In 2007, a team from the Brazilian Space Research Institute (INPE) coordinated by Paulo Roberto Martini determined the longest possible flow path with a total length of 6992 km on the basis of satellite images. This figure was also cited in the Encyclopædia Britannica , but as controversial (Alarich R. Schultz, Raymond E. Crist, James J. Parsons: Amazon River. As of May 25, 2017, accessed July 2017), partly because the study was not was published and because the Brazilian measure in the delta not as usual the shorter route through the Canal do Norte follows ( how Long is the Amazon River? Retrieved on December 31, 2018 (English). ). The measuring path follows the longest path of the flowing water and, on a large detour south around the island of Marajó, also tidal channels and the sea bays of Rio Pará and Baía de Marajó to the transition into the open Atlantic. The same research team also re-measured the Nile and estimated it to be 140 km shorter than the Amazon ( Estudo do INPE indica que o rio Amazonas é 140 km mais extenso do que o Nilo. INPE press release of July 1, 2008, retrieval in July 2017).
