This is a list of rivers by length . It includes rivers with a length over 1,000 km.
Definition of length
The length of a river is not always easy to calculate. It depends on the identification of the source, the identification of the mouth, and the precise measurement of the river length between source and mouth. As a result, the length measurements of many rivers are only approximations. In particular, there is disagreement whether the Amazon or the Nile is the world's longest river.
tributary with the farthest source is not always the one given the name of the river. For example, the farthest source of the Mississippi River system is the source of the Missouri River ; but a different tributary is identified as the Mississippi. When the river is measured from mouth to farthest source, it is called the Mississippi-Missouri . Also, it is hard to state exactly where a river begins as very often rivers are formed by seasonal streams, swamps , or changing lakes . In this article, length means the length of the river system, including all tributaries.
estuary that gradually widens and opens into the ocean; examples are the Amazon River and the Saint Lawrence River . Some rivers do not have a mouth, instead they evaporate, and the exact point where the river ends will vary seasonally.
maps . In these cases, the measured length of a river will depend on the scale of the map on which the measurement is based; in general, the larger the scale , the longer the resulting length measurement. Ideally, length measurements should be based on maps that are of a large enough scale to show the width of the river.
Longest rivers One should take the forementioned 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 parantheses.

Darling River (from the Murray River to Culgoa River ) The Murray River and its tributary , the Darling River , are the main rivers in the Murray-Darling River Basin. The Darling River flows south from the junction of the Culgoa and Barwon rivers .
What are the Longest Rivers in the World? (260 words)
The second and third longest river in the Amazon system, the Madeira and the Purus , respectively, are also the nineteenth and twentieth longest rivers in the world, while the two major portions of the Mississippi-Missouri-Red Rocks system are the sixteenth and seventeenth longest rivers in the world, respectively. The longest river in Australia is the Murray-Darling River at 1,572 miles (2,530 km). The next longest river in Europe , after the Volga , is the Danube , which ranks as the twenty-seventh longest river in the world.
