The sight of a river fascinates everyone. We always think about a river as calm flowing water that brushes more than stones at the bottom of the river. May be we envision some fishes in it too. Whatever we think, not all the rivers are calm, and there are some dangerous rivers in the globe as well.

The Congo River, earlier recognized as the Zaire River, is in Western Central Africa. It is Africa’s most powerful river and the second most voluminous river in the world. It is about 2992 miles long. The river is one among the dangerous ones because still it begins peacefully; it picks up speed and becomes turbulent until it enters the “Gates of Hell”, a 75 mile long canyon of treacherous rapids. There are about 32 cataracts, having as much power as all the rivers and falls in the United States. At the Upper Congo, the river ends with the Stanley waterfall, a 60 mile draw out of rapids.
The Yangtze River is the largest and longest river in Asia as well as China. It is about 3964 miles long and it finally empties into the East China Sea. With plenty of rainfall all year round, it is also called the Golden Watercourse. The river has gorges along its way which are known for its dangerous with fast-moving water also numerous shoals.
At several points there are deceitful whirlpools and the waters are extraordinarily turbulent. The river is also known for its flooding and dams which have been constructed have proved to be of no use. The tides of the Yangtze River are much stronger and hence the flooding. It has always been a powerful source of electricity.
The first to top the list is the Amazon River. The Amazon River located in South America is the largest and most dangerous river in the world because of its length, width and sheer volume. It accounts for about 20% of the world’s river flow into the oceans.
Because of its vast dimensions, it is sometimes called the River Sea. It is so big that there aren’t any two points which can be crossed by a bridge. It is more than 150 feet deep. During a flood season, the Amazon widens to cover its banks and the islands in the middle of the river. The Amazon River is known for high tidal waves as well.
The Brahmaputra River has its origin in the South Western Tibet and flows through Tibet, China, India and Bangladesh. It is about 1800 miles long. It is known for its flooding when the snow in the Himalayas melt and also for its tidal bare. This makes it more dangerous and stronger.
The Orinoco River is the third longest river in South America and is about 1330 miles long and flows through Columbia and Venezuela. Huge tropical forests cover the southwestern parts and large portions are still virtually inaccessible. Over 200 rivers are tributaries to this mighty river. It begins at the Delgado Chalbaud Mountain and as the river passes the forested terrain and waterfalls it slows.
Navigation on this part is through shallow dugout or canoe. Farther on, the waterfalls become rapids and are very difficult to navigate. It drains into the Atlantic Ocean. It often posts a threat to the people who live close to the river due to its coastal upwelling throughout the year.
The Mekong River is located in China. It runs through Burma, Thailand, Yunnan, Laos, Vietnam, and Cambodia. The Mekong is the 11th longest river in the world and the 7th longest in Asia. The river is said to be about 2,703 miles long. Because of the seasonal changes that cause variations in flow as well as the appearance of rapids and waterfalls in the river, the Mekong is extremely difficult to navigate. This river so strong that the level of the river located in Cambodia is lower than the high tide at sea! In 2000, the river’s rapids and tides became so overwhelming that it flooded, killing about 90 people.
The Mississippi River is the only river in the U.S. to make the list! The Mississippi River is the second largest in the U.S. It expands across 2,340 miles of land. It starts at Lake Itasca in Minnesota and travels all the way down to the Gulf of Mexico. Those who live along the banks of the river often have to fear its high tides and extremely powerful waters. Many of the levees that have been built to hold back the water have proven extremely unhelpful. In 2008, many were afraid that the river would over-flood even more than it already had. The water was topping levees and many had to be evacuated from their homes.
The Parana River is the 14th longest river in the world. Though most of the river is located in Brazil, it also runs through other parts of South America such as Argentina and Paraguay. The river is about 2,485 miles long and flows into three other rivers. On the southern part of the river, flooding is extremely common. The strong currents that the Parana brings have been said to erode river shores, destroy buildings, and cause many people to have to move out of their homes. The high winds and the El-Nino effect also play big roles in how powerful the river is.
Flowing through Eastern Siberia, the Lena River is the 10th longest river in the world, bringing water 2,734 miles until it flows into the Sea. The river flows northeast and joins with two other rivers and finally flows into the Laptev Sea. The river is known to have strong links to stream flow, especially during the summer and spring when the water is much warmer than usual. Once it is spring, the ice on the Lena River melts before the ice downstream does, which usually causes flooding because iceblocks hinder the flow of water. In 2007, the river over-flooded and more than 1,000 houses and 12 towns were under water.
The Yenisey River is the biggest river that flows into the Arctic Ocean. At 3,445 miles long, the river is the 5th largest in the world. The river flows through Mongolia, the Yenisei Gulf, and then drains in the center of Siberia. The upper part of the river is subject to floods a swell as rapids. Because part of the river exits through the Darkhad Valley, studies have shown that it is often blocked by ice. Once the glaciers retreat, it is said that as much as 500km ³ of water could escape from the river and cause a complete debacle.
