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.
Do rivers have strong currents?
Rivers flow from high points to lower ones and eventually down to a larger body of water. The force of gravity, which makes the water flow downward, creates river currents. Many factors contribute to the strength of river currents.
What river has the fastest current?

Where are the strongest currents in the world?
Saltstraumen is a small strait with one of the strongest tidal currents in the world. It is located in the municipality of Bodø in Nordland county, Norway. It is located about 10 kilometres (6.2 mi) southeast of the town of Bodø.
Where does a river flow very fast?
Characteristically youthful rivers are found at higher elevations, in mountainous areas, where the slope of the land is steeper. Water that flows over such a landscape will flow very fast.
How dangerous are river currents?
Strong currents can knock you down, rocks can trap your feet – grab the upstream end of your canoe, try to swim to shore. If caught against a rock – lean downstream.
What should you do if caught in a river current?

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.
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 oldest river in the world?
Finke River
The Finke River, which is also called Larapinta by the Aboriginal People, in central Australia is believed to be the oldest river in the world. While the Finke River’s exact age is unknown, it is at least over 300 million years old and some of the oldest parts of the river may be over 340 million years old.
What is the fastest current in the world?
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).
What ocean has the most powerful current?
The Antarctic Circumpolar Current is the planet’s most powerful and arguably most important current. It is the only current to flow clear around the globe without being diverted by any landmass.
Which ocean current is the most important?
The Antarctic Circumpolar Current is the only ocean current to circle the planet and the largest wind-driven current on Earth. It’s also 30% more powerful than scientists realized.
What is the beginning of a river called?
The place where a river begins is called its source. River sources are also called headwaters. Rivers often get their water from many tributaries, or smaller streams, that join together. The tributary that started the farthest distance from the river’s end would be considered the source, or headwaters.
Why does the flow of a river slow down near its mouth?
As a river flows, it picks up sediment from the river bed, eroding banks, and debris on the water. … The river slows down at the mouth, so it doesn’t have the energy to carry all the silt, sand, and clay anymore. These sediments form the flat, usually triangle-shaped land of a delta.
Why is the flow of a river fastest in the lower course?
Lower course – The gradient levels off, but the speed of the river is very fast because there is a low amount of friction acting on the river water. The river is very wide because of the vast amount of water and the vast amount of erosion that has occurred over the years.
