A stream gauge, streamgage or 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 made. The location of gauging stations are often found on.

The term stream gauging is used to mean measurement of discharge as well as river water level or stage in a general way. However, when a term gauge record is used it only means a record of river stages or water levels. Unlike the irrigation canals the depth of water varies along the cross-section of the river from one bank to the g: ultrasonics.

The second edition of Streamflow Measurement meets the demands of engineers and managers in the water industry on how to obtain information on the flow in the world's rivers in view of the decreasing availability of usable water.

It deals with all aspects of establishing, operating and maintaining streamflow measurement stations to ensure they provide maximum information.

The river is straight for a distance approximately equal to five channel widths upstream of the gauging station.

This will result in water levels that are generally the same across the river at the location of the gauge and will avoid affects caused by super elevation of the water surface that commonly occur on the outside of river bends. Search by city or zip code.

The average velocity of the water in the two 'end segments' (adjacent to the river banks) are calculated by assuming zero depth and zero velocity at the water's edge.

Current metering is an accurate method of river gauging except where the river is very shallow. Under such conditions, an alternative method of dilution gauging can be used. Stream gauging is the process of measuring the water discharge or flow at a particular point on a stream or river.

There are many reasons why someone might take stream gauging measurements, such as implementing a long term study for ecological reasons, establishing a baseline to compare future data to, and studying trends for future growth, to name a few.

In contrast to the raingauge network, which was well developed by the middle of the nineteenth century, gauging station construction in the UK was very spasmodic until the latter half of the 20th century.

Routine flow measurement of the Thames and Lee began in the s and, in Scotland, Captain W. McClean initiated a small pioneering gauging station network prior to the First World War.
