10. Lena River, Russia: 2,734 miles

The Lena is the easternmost of the three great Siberian rivers that flow into the Arctic Ocean (the other two being the Ob River and the Yenisei River). It is the 10th longest river in the world and has the 9th largest watershed. It is the greatest Russian river with its watershed entirely within national ranges. Rising at the height of 1,640 metres (5,381 ft) at its source in the Baikal Mountains south of the Central Siberian Plateau, 7 kilometres (4 mi) west of Lake Baikal, the Lena flows northeast, being joined by the Kirenga River, Vitim River and Olyokma River. From Yakutsk it enters the lowlands and flows north until joined by its right-hand affluent the Aldan River. The Verkhoyansk Range deflects it to the north-west; then, after receiving its most important left-hand tributary, the Vilyuy River, it makes its way nearly due north to the Laptev Sea, a division of the Arctic Ocean, emptying south-west of the New Siberian Islands by the Lena Delta – 30,000 square kilometres (11,583 sq mi) in area, and traversed by seven principal branches, the most important being Bykov, farthest east.

9. Amur River, Northeast Asia: 2,744 miles

The Amur River, or Heilong Jiang, or Sahaliyan Ula, is the world’s ninth longest river, forming the border between the Russian Far East and Northeastern China. It rises in the hills of western Manchuria at the confluence of its two major affluents, the Shilka River and the Argun River, at an elevation of 303 metres (994 ft). It flows east forming the border between China and Russia, and slowly makes a great arc to the southeast for about 400 kilometres (250 mi), receiving many tributaries and passing many small towns. At Huma, it is joined by a major tributary, the Huma River. Afterwards it continues to flow south until between the cities of Blagoveschensk (Russia) and Heihe (China), it widens significantly as it joins the Zeya River, one of its most important tributaries.

8. Congo River, Central Africa: 2,914 miles

The Congo River (also known as the Zaire River) is the largest river in Western Central Africa. Its overall length of 4,700 km (2,920 mi) makes it the second longest in Africa (after the Nile). The river and its tributaries flow through the Congo Rainforest, the second largest rain forest area in the world, second only to the Amazon Rainforest in South America. The river also has the second-largest flow in the world, behind the Amazon; the second-largest drainage basin of any river, again trailing the Amazon; and is the deepest river in the world, at depths greater than 230 m (750 ft). Its drainage basin is slightly larger than that of the Mississippi. Because large sections of the river basin lie above and below the Equator, its flow is stable, as there is always at least one part of the river experiencing a rainy season. The Congo gets its name from the ancient Kingdom of Kongo which inhabited the lands at the mouth of the river. The Democratic Republic of the Congo and the Republic of the Congo, both countries lying along the river’s banks, are named after it. Between 1971 and 1997 the government of then-Zaire called it the Zaire River.

7. Ob-Irtysh, Russia: 3,354 miles

The Ob River, also Obi, is a major river in western Siberia, Russia. It is the country’s fourth longest. The Ob River also has the longest estuary in the world. The Ob is formed 16 miles (26 km) southwest of Biysk in Altai Krai by the confluence of the Biya and Katun rivers. Both these streams have their origin in the Altay Mountains, the Biya issuing from Lake Teletskoye, the Katun, 80 miles (130 km) long, bursting out of a glacier on Mount Byelukha. The Ob zigzags west and north until it reaches 55° N, where it curves round to the northwest, and again north, wheeling finally eastwards into the Gulf of Ob, a 600-mile (970 km)-long bay of the Kara Sea, which adjoins the Arctic Ocean.

6. Huang He, China: 3,395 miles

The Yellow River or Huang He / Hwang Ho is the second-longest river in China (after the Yangtze River) and the sixth-longest in the world at the estimated length of 5,464 kilometers (3,395 mi) Originating in the Bayan Har Mountains in Qinghai Province in western China, it flows through nine provinces of China and empties into the Bohai Sea. The Yellow River basin has an east-west extent of 1900 km (1,180 mi) and a north-south extent of 1100 km (684 mi). Total basin area is 742,443 km² (290,520 mi²). The Yellow River is called “the cradle of Chinese civilization”, as its basin is the birthplace of the northern Chinese civilizations and was the most prosperous region in early Chinese history. But frequent devastating flooding largely due to the elevated river bed in its lower course, has also earned it the unenviable name “China’s Sorrow”.

5. Yenisey, Russia: 3,434 miles

Yenisei, also written as Yenisey, is the greatest river system flowing to the Arctic Ocean. Rising in Mongolia, it follows a northerly course to the Yenisei Gulf in the Kara Sea, draining a large part of central Siberia, the longest stream following the Yenisei-Angara-Selenga-Ider.  The upper reaches, subject to rapids and flooding, pass through sparsely populated areas. The middle section is controlled by a series of massive hydroelectric dams fuelling significant Russian primary industry. Partly built by gulag labor in Soviet times, industrial contamination remains a serious problem in an area hard to police. Moving on through sparsely-populated taiga, the Yenisei swells with numerous tributaries and finally reaches the Kara Sea in desolate tundra where it is icebound for more than half the year.  Maximum depth of Yenisei River is 80 feet (24 m) and average depth is 45 feet (14 m). The depth of river goes outflow 106 feet (32 m) and river goes inflow 101 feet (31 m).

4. Mississippi-Missouri River, USA: 3,870 miles

The Mississippi River is the largest river system in the United States and the largest of North America. About 2,320 miles (3,730 km) long, the river originates at Lake Itasca, Minnesota and flows slowly southwards in sweeping meanders, terminating 95 river miles below New Orleans, Louisiana where it begins to flow to the Gulf of Mexico. Along with its major tributary, the Missouri River, the river drains all or parts of 31 U.S. states stretching from the Rocky Mountains in the west to the Appalachian Mountains in the east to the Canada-U.S. border on the north, including most of the Great Plains, and is the fourth longest river in the world and the tenth most powerful river in the world. on yon Mississippi River.jpg

3. Chang Jiang (Yangtze) River, China: 3,917 miles

The Yangtze River, or Chang Jiang (Cháng Jiāng; literally “The Long River”), Tibetan: ‘Bri-chu, is the longest river in China and Asia, and the third-longest in the world. The river is about 6,300 kilometres (3,915 mi) and flows from its source in Qinghai Province, eastwards into the East China Sea at Shanghai. It acts as a dividing line between North and South China, although geographers generally consider the Qinling-Huai River line to be the official line of geographical division. As the largest river in the region, the Yangtze is historically, culturally, and economically important to China. One of the dams on the river, the Three Gorges Dam, is the largest hydro-electric power station in the world. The section of the river flowing through deep gorges in Yunnan province is part of the Three Parallel Rivers of Yunnan Protected Areas: a UNESCO World Heritage Site.

2. Amazon River, South America: 3,980 miles

The Amazon River (Portuguese: Rio Amazonas; Spanish: Río Amazonas; pronounced /ˈæməzɒn/ (US); /ˈæməzən/ (UK)) of South America is the largest river in the world by volumetric discharge, with a total river flow greater than the next ten largest rivers combined. The Amazon, which has the largest drainage basin in the world, accounts for approximately one-fifth of the world’s total river flow.[1]  In its upper stretches the Amazon river is called Apurímac (in Peru) and Solimões (in Brazil).  During the wet season, parts of the Amazon exceed 190 kilometres (120 mi) in width. Because of its vast dimensions, it is sometimes called The River Sea. At no point is the Amazon crossed by bridges.[2] This is not because of its huge dimensions; in fact, for most of its length, the Amazon’s width is well within the capability of modern engineers to bridge. However, the bulk of the river flows through tropical rainforest, where there are few roads and even fewer cities, so there is no need for crossings. Cradle of Civilization/1 amazon river.jpg

1. Nile, North/East Africa: 4,135 miles

The Nile is a major north-flowing river in Africa, generally regarded as the longest river in the world.[1]  The Nile has two major tributaries, the White Nile and Blue Nile, the latter being the source of most of the Nile’s water and fertile soil, but the former being the longer of the two. The White Nile rises in the Great Lakes region of central Africa, with the most distant source in southern Rwanda at 2°16′55.92″S 29°19′52.32″E / 2.2822°S 29.3312°E / -2.2822; 29.3312, and flows north from there through Tanzania, Lake Victoria, Uganda and southern Sudan, while the Blue Nile starts at Lake Tana in Ethiopia at 12°2′8.8″N 37°15′53.11″E / 12.035778°N 37.2647528°E / 12.035778; 37.2647528, flowing into Sudan from the southeast. The two rivers meet near the Sudanese capital of Khartoum.  The northern section of the river flows almost entirely through desert, from Sudan into Egypt, a country whose civilization has depended on the river since ancient times. Most of the population and cities of Egypt lie along those parts of the Nile valley north of Aswan, and nearly all the cultural and historical sites of Ancient Egypt are found along the banks of the river. The Nile ends in a large delta that empties into the Mediterranean
