Here, only those rivers whose discharge is more than 2,000 m 3 /s (71,000 cu ft/s) are shown. It can be thought of as a list of the biggest rivers on Earth, measured by a specific metric. It can be thought of as a list of the biggest rivers on Earth, measured by a specific metric.
All rivers with average discharge more than 15,000 cubic feet per second are listed. Estimates are approximate, because data are variable with time period measured and also because many rivers lack a gauging station near their point of outflow.
Thus the water discharge of a tap (faucet) can be measured with a measuring jug and a stopwatch. Here the discharge might be 1 litre per 15 seconds, equivalent to 67 ml/second or 4 litres/minute. This is an average measure. For measuring the discharge of a river we need a different method and the most common is the 'area-velocity' method.
This chart displays the Annual Mean Discharge of the Potomac River measured at Little Falls, Maryland for Water Years 1931–2017 (in cubic feet per second). Source of data: USGS. [2] The average daily flow during the water years 1931–2018 was 11,498 cubic feet (325.6 m 3) /s. [2]
The Congo River, [a] formerly also known as the Zaire River, is the second-longest river in Africa, shorter only than the Nile, as well as the third-largest river in the world by discharge volume, following the Amazon and Ganges rivers. It is the world's deepest recorded river, with measured depths of around 220 m (720 ft). [10]
The Shenandoah River was contaminated with mercury which was released by a DuPont rayon manufacturing facility located in Waynesboro, Virginia from 1929 to 1950. [6] This mercury is still present in the fish population of the river today; data collected over the last several decades shows that mercury levels remain stable. [7]
The development of a rating curve involves two steps. In the first step the relationship between stage and discharge is established by measuring the stage and corresponding discharge in the river. And in the second part, stage of river is measured and discharge is calculated by using the relationship established in the first part.
Annual Colorado River discharge volumes at Lee's Ferry between 1895 and 2004. The unimpaired annual runoff [n 6] of the Colorado River at Lees Ferry, Arizona is estimated at 14.7 million acre-feet (18.1 km 3), or an annualized discharge of 20,300 cu ft/s (570 m 3 /s), for the 1906–2023 period. [71]
