How do you find the speed of a river current?
- The distance going upstream and downstream is the same.
- Time going upstream is 3 hours.
- Time going downstream is 2 hours.
- Speed of the boat (r) is 5 miles per hour.
- Distance (d) = rate (r) X time (t)
What makes rivers flow faster?
1. Generally a narrower more circular river channel allows faster flow of water. Broader flat channels tend to slow a river down. … Generally anything that increases the surface area of the channel against which the water flows will tend to slow the flow because of the increase in friction.
What is the average flow rate of a river?
Average river surface velocities ranged between 0.60 m/s and 0.76 m/s (table 1).
What is the strongest flowing river?
The greatest flow of any river in the world is that of the Amazon which discharges an average of 200 000 m³/sec (7 100 000 ft³/sec) into the Atlantic Ocean increasing to more than 340 000 m³/sec (12 000 000 ft³/sec) in full flood.
How fast is the Amazon river?
What is the fastest moving 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).
What is the speed of the boat in still water it takes 2 hours?
…

Do rivers flow at a constant speed?
4. River Flow. River flow is driven by the hydrostatic pressure gradient which is constant across the whole cross section of the river. Were it not for viscosity effects this would mean that the stream flowed at an equal speed at all points within the cross-section since each point is driven with the same force.
What is the speed of the current?
It’s the electromagnetic wave rippling through the electrons that propagates at close to the speed of light. The dimensions of the wire and electrical properties like its inductance affect the exact propagation speed but usually it will be around 90 per cent of the speed of light – about 270 000 km/s.
Can a river have more than one mouth?
What is considered fast moving water?
According to the NFPA if water flows faster than 1.85 km/h it is considered to be “moving” water or “swiftwater”. … It is also means that flood water can usually be classified as moving or swiftwater and therefore also requires additional training for those who work in flood conditions.
How do you slow down a river flow?
There are various ways to slow the flow of runoff water caused by heavy rainfall. Two techniques are: Partial manmade barriers (‘drop structures’ ‘check dams’) placed in streams on steep slopes to reduce the average water velocity (think: manmade waterfalls beavers!).
How deep can a river get?
…

Are streams deep?
In general small streams may be as deep as as they are wide whereas large streams usually have widths many times greater than their depths. 3. The gradient of a stream is a measure of the vertical distance that a stream channel falls between two points along its course.
Which river discharges the most water in the world?
| No | Continent | River |
|---|---|---|
| 1 | South America | Amazon |
| 2 | Africa | Congo (Zaire) |
| 3 | Asia | Ganges/Brahmaputra/Meghna |
| 4 | South America | Orinoco |
Which is the deadliest river in the world?
The Zambezi is considered by many to be the world’s most dangerous river which is partly what drew me. It’s almost 3 000km long peppered with unexploded mines killer rapids and deadly animals. Before the expedition I joined a wildlife survey that counted 188 000 crocodiles and 90 000 hippos along its length.
What is the world’s shortest river?
The Roe River

Which state has the most river?
Alaska has the most bodies of water with over 3 000 000 at last count. that is both lakes and rivers. Nebraska has more miles of rivers than any other state in the country. Four major rivers exist in Nebraska in addition to smaller ones.
How deep does the Amazon River get?
100 m
How warm is the Amazon River?
-The year-around water temperature of the Amazon river between Belem and Manaus ranges from 84° F to 86° F. The temperature profiles taken from the surface to the bottom show that mixing of the river by turbulence maintains a constant temperature throughout the river’s depth.
Why is the Amazon River called the king of waters?
The first European to explore the Amazon in 1541 was the Spanish soldier Francisco de Orellana who gave the river its name after reporting pitched battles with tribes of female warriors whom he likened to the Amazons of Greek mythology.

What is the speed of the boat in still water it takes 7 hours?
Speed of a boat in still water is 7 km/hr and speed of the stream is 1.5 km/hr . How much time will it take to move up is stream of a distance 7.7 km? Description for Correct answer: t=dv1+v2=7.77−1.5=75hrs.

What is the speed of the boat in still water?
The speed of a boat in still water is 11 km/hr. It can go 12 km upstream and return downstream to its original point in 2 hr 45 min.
Why rivers are not straight?
Where is river velocity highest?
midstream
Stream velocity is greatest in midstream near the surface and is slowest along the stream bed and banks due to friction.
