# How do you calculate the volume of a river?

## How do you calculate the volume of a river?

More specifically, water discharge, which is the volume of water moving through the cross section of a stream or river during a particular unit of time, is typically computed by multiplying the area of water in a channel cross section by the average velocity of the water in that cross section.

### What is river volume?

River discharge is the volume of water flowing through a river channel. This is the total volume of water flowing through a channel at any given point and is measured in cubic metres per second (cumecs). The discharge from a drainage basin depends on precipitation, evapotranspiration and storage factors.

#### What is the rate of water flow in a river channel?

Measurement. Streamflow is measured as an amount of water passing through a specific point over time. The units used in the United States are cubic feet per second, while in majority of other countries cubic meters per second are utilized. One cubic foot is equal to 0.028 cubic meters.

How do you calculate the flow of a river?

To calculate the water flow (in m3/s) multiply the average water velocity by the average cross-section. To express this water flow in litres per second (l/s), multiply the result (in m3/s) by 1000.

What river has the most volume of water?

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.

## How do you calculate the velocity of a river?

Multiply the average depth of the stream by the width of the stream to find the area in ft2. Divide the distance traveled by the average travel time to find the velocity of the stream in ft/sec.

### What’s the largest river by volume?

The Amazon River
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.

#### Why is streamflow monitoring so important?

Streamflow information is required to determine how much water is available in different locations so the citizens can make informed decisions about growth and to help assure there is an adequate water supply even during periods of drought.

What is the answer of flow of water in a channel?

Answer: Flow of water in a water channel is called as a stream flow or channel runoff.

How is water measured?

Basic units of water measurement

1. Cubic feet per second (cfs): * 1 cubic foot = 7.4805 gallons. * 1 cubic foot per second = 7.4805 gallons flowing by a particular point in 1 second.
2. Acre-foot (af): * 1 acre = 43,560 square feet.
3. Other conversions: * 1 US gallon = 0.1337 cubic feet = 3.79 liters.

## What are the top 3 largest volume rivers?

List of rivers by discharge

2 Africa Congo (Zaire)
3 Asia Ganges-Brahmaputra/Meghna
4 South America Orinoco
