A stream gauge, streamgage or stream gauging station is a location used by hydrologists or environmental scientists to monitor and test terrestrial bodies of water. Hydrometric measurements of water level surface elevation ("stage") and/or volumetric discharge (flow) are generally taken and observations of biota and water quality may also be ...
This is a list of rivers in the continental United States by average discharge (streamflow) in cubic feet per second. All rivers with average discharge more than 15,000 cubic feet per second are listed.
Additionally, USGS uses hydrographs to study streamflow in rivers. A hydrograph is a chart showing, most often, river stage (height of the water above an arbitrary altitude) and streamflow (amount of water, usually in cubic feet per second). Other properties, such as rainfall and water quality parameters can also be plotted.
This article lists rivers by their average discharge measured in descending order of their water flow rate. 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. For context, the volume of an Olympic-size ...
Runoff is the flow of water across the earth, and is a major component in the hydrological cycle. Runoff that flows over land before reaching a watercourse is referred to as surface runoff or overland flow. Once in a watercourse, runoff is referred to as streamflow, channel runoff, or river runoff . Urban runoff is surface runoff created by ...
The gradual decay in flow after the peaks reflects diminishing supply from groundwater. A hydrograph is a graph showing the rate of flow ( discharge) versus time past a specific point in a river, channel, or conduit carrying flow. The rate of flow is typically expressed in cubic meters or cubic feet per second (cms or cfs).
The water needs of irrigators downstream from the canyon mouths are satisfied with water diverted out of the Jordan River and transported across the valley in a system of canals. Some of the water from the Jordan River is imported to the urbanized reach of Little Cottonwood Creek. The flood stage for the urban waterways is 5.7 feet (1.7 m).
United States Geological Survey (USGS) / 38.9470; -77.3675. The United States Geological Survey ( USGS ), founded as the Geological Survey, is an agency of the United States government whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United ...
