Top 3 Longest Rivers in the World

The specific meaning of “river length” is determined by the identification of the source, the identification or definition of the mouth, and the scale of measurement of the river length between source and mouth. As a result, many river length estimates are simply educated assumptions (see also coastline paradox). The debate over whether the Nile or the Amazon is the world’s longest river appears to be raging. The Nile had long been thought to be the longer river, however some scientists stated that the Amazon was longer after surveying the river, the adjacent Pará estuary, and the longest connected tidal canal in 2007 and 2008.

1. Nile River (6,650km)

Nile river

On the continent of North Africa, the Nile is a major north-flowing waterway. As a result, it drains into the Mediterranean Sea. Historically, it was considered the world’s longest river due to its length, but new study indicates that the Amazon River may be slightly longer. By volume of water flowing yearly, the Nile is one of the smallest of the world’s major rivers. Its drainage basin is approximately 6,650 kilometres (4,130 mi) long and spans eleven nations. The Nile’s two largest tributaries are the White Nile, which starts in Jinja, Uganda and goes into Lake Victoria, and the Blue Nile, which runs into Egypt. The White Nile is said to be the Nile’s sources and main stream. The Blue Nile, on the other hand, is the main source of water, accounting for 80% of all fluid and silt. The White Nile is a larger river that flows through the Great Lakes region. It starts at Lake Victoria in Uganda and ends in South Sudan. The Blue Nile begins in Lake Tana in Ethiopia and flows southeast into Sudan. Just north of Sudan’s capital, Khartoum, the two rivers meet.

The Blue Nile (Amharic: bay) rises from Lake Tana in the Ethiopian Highlands. The Blue Nile flows for more than 1,400 kilometres to Khartoum, where it merges with the White Nile to form the Nile. The Blue Nile contributes 59% of the water and 96% of the transportable sediment carried by the Nile, with Ethiopia providing 90% of the water and 96% of the transportable silt.

Did You Know?

The Nile crocodile is one of the world’s largest and deadliest reptiles. 275 to 745 attacks occur per year, according to one estimate (about 63 percent of which are fatal). Once located all the way up to the Nile Delta, these aggressive reptiles’ natural habitat has shrunk due to human interference.

2. Amazon River (6,400km)

Amazon river

The Amazon River is both the world’s largest river in terms of flow volume and the world’s disputed longest river. For nearly a century, the Apurmac River’s headwaters on Nevado Mismi were assumed to be the Amazon’s most distant source, until a 2014 study found that it actually the Mantaro River’s headwaters on Peru’s Cordillera Rumi Cruz. The Mantaro and Apurmac rivers merge to form the Ucayali River, which meets the Maraón River upstream of Iquitos, Peru, to form what is considered the main stem of the Amazon by countries other than Brazil. Above its confluence with the Rio Negro, Brazilians refer to this part of the river as the Solimes River. The Amazon, as it is regarded in Brazil, was formed at the Meeting of Waters (Portuguese: Important intervention das Guas) in Manaus, the lake’s principal town. the Amazon River accounts for 20% of worldwide riverine release to the ocean, more than the next seven leading independent rivers combined. With an extent of around 7,000,000 square kilometres, the Amazon region is the world’s biggest hydrological basin (2,700,000 sq mi). The drainage system of the river in Brazil itself is greater than that of any other river. Although the Amazon only has one-fifth of the flow it eventually empties into the Atlantic Ocean when it enters Brazil, it already has a bigger flow than any other river at this stage.

Despite the fact that the Amazon river is unaffected by dams, the Amazon’s subsidiary rivers are home to roughly 412 dams. Six of the major feeder rivers that flow into the Amazon have 151 dams built over them. More flooding initiatives have been launched, with hundreds more planned, but only 4% of the Amazon’s hydroelectric potential has been utilized in countries like Brazil. After observing the bad impacts of the Three Gorges Dam in the Yangtze River on biodiversity loss, sedimentation, route planning, and flood mitigation, scientists are concerned that building more dams in the Amazon will impact its ecosystems in the identical way by blocking fish-spawning runs, lowering the streams of essential oil nutrient content, and emptying forests.

Did You Know?

Vicente Yáez Pinzón, a Spaniard, became the first known European to sail up the Amazon River in March of 1500. However, in 1541, Francisco de Orellana, a fellow Spaniard, became the first European to sail the full length of the Amazon River. Because a group of female warriors on the river ambushed his expedition, he called it after the warrior ladies of Greek mythology.

3. Yangtze River (6,300km)

Yangtze river

The Yangtze is Asia’s major river, the third in the globe, and the longest and largest river that runs entirely within a single country. It runs east for 6,300 kilometres (3,900 miles) from Jari Hill in the Tanggula Mountains (Tibetan Plateau) to the East China Sea. By flow quantity, it is the world’s sixth-largest river. Its drainage system encompasses one-fifth of China’s land area and is home to roughly a third of the population. In China’s history, culture, and economy, the Yangtze has played a vital role. The water has been used for drainage, agriculture, sewage, commerce, industry, boundary-marking, and battle for thousands of years. The Yangtze River Delta is so affluent that it contributes up to 20% of China’s GDP. The Three Gorges Dam on the Yangtze River is the world’s largest hydroelectric power facility. The Chinese government declared in mid-2014 that it will construct a multi-tier transportation network, including railways, highways, and airports, to create a new economic belt around the river.

The Yangtze is flanked by industrial belts and high-tech development zones in the metallurgical, power, chemical, car, building materials, and equipment industries. It is becoming an essential link for international shipping to the inland provinces, and it is playing an increasingly important role in the river valley’s economic growth. The river connects China’s heartland to the coast and is an important transportation artery.

The river is one of the globe’s fastest. Industrial transportation includes the transportation of bulk commodities such as coal, as well as manufactured products and passengers. Cargo traffic was 795 million tonnes in 2005. Longer river cruises, particularly through the magnificent and breathtaking Three Gorges area, are growing increasingly popular as China’s tourism industry grows.

Did You Know?

China’s Three Gorges Dam on the Yangtze River is the world’s largest hydroelectric power facility. It’s critical for things like flood management, electricity generation, shipping, aquaculture, tourism, and irrigation, to name just a few. Annually, 100 billion kWh of power is generated, enough to supply the daily energy demands of over 200 million people in a dozen regions.
