We are here again with the post about top ten longest rivers in the world. All the rivers and main tributaries of over 1000 km in length. Watercourses are listed here in the usual hydrographic criteria, that is, determining the length of a river by the length of its most remote source, regardless of the river all the way keep the same name. Following are some of the longest rivers in the world:

1. Amazon River: The Amazon is the largest and longest river in the world , having the length of more than 6,800 km. Its watershed is the largest in the world .

However its basin covers nine countries, which includes Brazil, Bolivia , Peru , Ecuador , Colombia , Venezuela , Guyana, French Guiana and Suriname. Its drainage basin is 7,050,000 km2 , which represents almost 40% of South America. The Amazon river system has over a thousand major tributaries, of which exceed twenty-five thousand miles long. The river network is more than 100,000 km of rivers that make up the Amazon basin of which depends the existence of the forest. 50% of rainfall in this region occur because of this forest system .

Most of the population of Egypt and all its cities – except for the Nile Delta and oases , are found along the Nile valley north of Aswan, and most places of cultural interest are historical and along the riverbanks . The mouth of the river forms the Delta of the Nile, which flows into the Mediterranean Sea .
