Rivers of the world.

Rio Grande

Rio Grande is one of the principal rivers (along with the Colorado River) in the southwest United States and northern Mexico. The Rio Grande begins in south-central Colorado in the United States and flows to the Gulf of Mexico. Along the way, it forms part of the Mexico-United States border. According to the International Boundary and Water Commission, its total length was 1,896 miles (3,051 km) in the late 1980s, though course shifts occasionally result in length changes. Depending on how it is measured, the Rio Grande is either the fourth- or fifth-longest river system in North America.

Danube River

The Danube, known by various names in other languages, is Europe's second longest river, after the Volga. It is located in Central and Eastern Europe. The Danube was once a long-standing frontier of the Roman Empire, and today flows through 10 countries, more than any other river in the world.

Mekong River

The Mekong river is the 12th longest river in the world with an estimated length of 4,350 km (2,703 miles),. From the Tibetan Plateau this river runs through China's Yunnan province, Burma, Laos, Thailand, Cambodia and Vietnam. The river is difficult to navigate due to the extreme seasonal variations in flow and the presence of rapids and waterfalls. The Mekong basin is one of the richest areas of biodiversity in the world which is only surpassed by the Amazon.

Mississippi River

The Mississippi River is the largest river system in the United States and North America. The river originates at Lake Itasca, and empties below New Orleans in the Gulf of Mexico. Along with its major tributary, the Missouri River, the river drains all or parts of 31 U.S. states.

Amazon River

the Amazon River is the second longest river in the world, just slightly shorter than the Nile although reputable sources disagree as to the exact length of the two rivers. What is certain is that the Amazon is the largest river in the world by volume, with a total river flow that accounts for approximately one-fifth of the world's total. The Amazon and its tributaries flow through Peru, Bolivia, Venezuela, Colombia, Ecuador, and Brazil before emptying into the Atlantic Ocean.

Yangtze River

One of the most important rivers in the world, the Yangtze River is the longest river in China, and the third-longest in the world. The river is about 6300 km long (3915 miles) and originates in a glacier lying on the eastern part of the Tibetan plateau. It passes through the spectacular Yangtze Gorges, which are noted for their natural beauty, and flows into the East China Sea. One of the dams on the river, the Three Gorges Dam, is the largest hydro-electric power station in the world.

Murray River

The Murray River is Australia's longest river, at 2,508 kilometres (1,558 mi) in length. The Murray rises in the Australian Alps, draining the western side of Australia's highest mountains, and then meanders across Australia's inland plains, forming the border between the states of New South Wales and Victoria as it flows to the northwest into South Australia. It turns south at Morgan for its final 315 kilometres (196 mi), reaching the ocean at Lake Alexandrina.

Nile River

The Nile is the longest river in the world, stretching north for 6,650 km (4,132 miles) from East Africa to the Mediterranean. The Nile has two major tributaries, the White Nile and Blue Nile. The White Nile rises in the Great Lakes region of central Africa while the Blue Nile starts at Lake Tana in Ethiopia.

Yenisey River

The Yenisey River is the largest river system flowing to the Arctic Ocean. It is the central of the three great Siberian rivers that flow into the Arctic Ocean (the other two being the Ob and the Lena). 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 river system.

Congo River

The great Congo River is the second longest river in Africa, shorter only than the Nile, as well as the second largest river in the world by discharge volume, following only the Amazon. It is also the world's deepest recorded river, with measured depths in excess of 220 m.
