Top 10 Longest Rivers in the World

Rivers form an integral part of our ecosystem and help to maintain the natural environmental balance of earth. About three-fourth of the world comprises of water. Deep down the rivers, there is a whole new world to explore and one comes to know about the umpteen different creations o f the nature. River is also the source of hydro-electric power and is also used for transport from one point to another. Few of you might be familiar with the term “International Scale of River Difficulty”. This is actually a grading system in which particular grades are assigned to a section of river which speaks of the challenges of navigation for that specific section. The grades range from Class I (the easiest) to Class VI (the hardest).

After a short introduction of the topic, let us move on with the topic. Please note that all the figures regarding the lengths of the rivers are a mere approximation and there can be a little bit discrepancies when viewed from some other source.





10. Zaire

This African river is approximately 2716 miles long and is also known as Congo River. It is also the world’s deepest river with a depth of around 220 meters.

2. Amazon

The average length of the river is around 3912 miles. Although it ranks second in terms of length but it is ranked number one when it comes to the average discharge. The discharge of Amazon is greater than the next seven largest rivers combined. The average width of the river is between 1.6 to 10 kilometers and maximum is around 48 kilometers in the wet season. Nevado Mismi, a snow-capped peak present in the Peruvian Andes, is thought to be the origin of the Amazon River and this specific point is marked with a wooden cross.



1. Nile

The average length of the river Nile is around 4180 miles. Being the world’s longest river, it is little wonder that it flows through almost ten countries namely; Sudan, South Sudan, Burundi, Rwanda, Democratic Republic of the Congo, Tanzania, Kenya, Ethiopia, Uganda and Egypt. Among the two tributaries of Nile, White Nile is the longer one and the other one being the Blue Nile.
