A river is a natural freshwater stream that flows on land or inside caves towards another body of water at a lower elevation, such as an ocean, lake, or ...
The average flow rate at the mouth of the Amazon is sufficient to fill more than 83 such pools each second. The estimated global total for all rivers is 1.2 × 10 6 m 3 /s (43 million cu ft/s), [ 1 ] of which the Amazon would be approximately 18%.
In dry regions, cultivated, and urbanized areas, overland flow or surface runoff is usually a major source of streamflow. Overland flow is a stormwater runoff that begins as thin layer of water that moves very slowly (typically less than 0.25 feet per second) over the ground. Under intensive rainfall and in the absence of barriers such as rough ...
Reversing Falls of Saint John River A number of rivers are known to have reversed the direction of their flow, either permanently or temporarily, in response to geological activity, weather events, climate change , tides, or direct human intervention.
A reversal flow of the Chicago River into Lake Michigan would have a negative impact on navigation and on the quality of Lake Michigan water, which is the source of drinking water.

A stone near Crissolo, Italy, is inscribed, "Here is born the Po".. The United States Geological Survey (USGS) states that a river's "length may be considered to be the distance from the mouth to the most distant headwater source (irrespective of stream name), or from the mouth to the headwaters of the stream commonly known as the source stream".
The Cedar River Flow is a remote 640 acres (2.6 km 2) shallow lake, created by the Wakely Dam on the Cedar River, where there are a number of campsites accessible via a gravel road, 14 miles (23 km) from Indian Lake or 23 miles (37 km) from Inlet.
