| Rank | River | Average discharge (m3/s) |
|---|---|---|
| 1 | Amazon | 2,09,000 |
| 2 | Congo | 41,200 |
| 3 | Ganges – Brahmaputra – Meghna | 38,129 |

Where is the current fastest in a river?
The speed of the current in a river is faster in a narrow place than a wider place. The current is faster at a place where the bottom of a river is steep. A place where water flows fast in a river is where the width is narrow and the bottom steep. An example of such a river would be in a gorge of the upper reaches.
What river has the strongest current?
Amazon River
This river is so powerful and so big that there aren’t any points along the river that can be crossed by a bridge. The river has an extremely powerful discharge at the mouth which can release as much as eight trillion gallons of water each day.
What is the fastest flowing river in the United States?
Off the Atlantic seaboard of the United States, the Gulf Stream flows at a rate nearly 300 times faster than the typical flow of the Amazon River. The velocity of the current is fastest near the surface, with the maximum speed typically about 5.6 miles per hour (nine kilometers per hour).
Which streams rivers tend to flow the fastest?
Toward the middle of a river, water tends to flow fastest; toward the margins of the river it tends to flow slowest. 2. In a meandering river, water will tend to flow fastest along the outside bend of a meander, and slowest on the inside bend.
What is the slowest river in the world?
The Everglades is the world’s slowest-moving river. When rain fills Lake Okeechobee, in south-central Florida, the lake overflows into the 50-foot wide, 1.5 million acre water filtration system and flows about one meter an hour toward the Gulf of Mexico, at the southern tip of the Sunshine State.
Where is erosion greatest in a river?
Most river erosion happens nearer to the mouth of a river. On a river bend, the longest least sharp side has slower moving water. Here deposits build up. On the narrowest sharpest side of the bend, there is faster moving water so this side tends to erode away mostly.
What is the deepest river in the world?
From its tributaries to where it meets the Atlantic Ocean, the massive river includes rapids, wetlands, floodplains, lakes and swamps. In addition, the Congo River is the world’s deepest recorded river at 720 feet (220 meters) deep in parts — too deep for light to penetrate, The New York Times reported.
What is the deepest river in the USA?
The deepest river in the United States is the Hudson River, which reaches 200 feet deep at some points.
What river holds the most water?
The Amazon River is 3,980 miles (6,400 kilometers) long, according to the U.S. National Park Service. It is, however, the world’s largest river by volume and contains 20 percent of the Earth’s fresh water, according to the National Science Foundation.
Which is longer the Nile or the Amazon?
The Amazon is considered the world’s largest river by volume, but scientists have believed it is slightly shorter than Africa’s Nile. The Brazilian scientists’ 14-day expedition extended the Amazon’s length by about 176 miles (284 kilometers), making it 65 miles (105 kilometers) longer than the Nile.
Is the Columbia River bigger than the Mississippi?
By volume, inside the U.S., the Columbia River’s mean annual discharge is outranked by: The Mississippi River – 593,000 cubic feet per second. The St. Lawrence River – 348,000 cubic feet per second.
Is Ohio or Mississippi River bigger?
The Ohio River is a left (east) and largest tributary by volume of the Mississippi River in the United States. At the confluence, the Ohio is considerably bigger than the Mississippi, measured by long-term mean discharge.
What three factors affect how fast a river flows?
What three factors affect how fast a river flows and how much sediment it can erode? A river’s slope, volume of flow, and the shape of its streambed.
What is it called when a slow moving river drops its load?
Deposition. The main way in which deposition happens is through loss of speed. When a river slows down on the inside of bends or when it meets deeper water – such as a lake – it loses energy and cannot carry so much. This causes it to drop some of its load.
Why do rivers flow faster on the outside?
A larger river channel means there is less friction, so the water flows faster: … The force of the water erodes and undercuts the river bank on the outside of the bend where water flow has most energy due to decreased friction.
