A streamgage is a collection of tools that measure and keep track of the volume of water moving through a river, stream, or outflow. In times of flooding, these measurements typically happen automatically every 15 minutes or more frequently.
Stream gauging is a method for measuring a stream's discharge, or the amount of water passing through a channel in a given amount of time.
The dischage in a stream can be calculated from the height of water in the stream channel, sometimes referred to as the stage or gauge height.
The height of the water in a stream above a reference point is known as gauge height, often referred to as stage. Gage height, as opposed to stream length, only refers to the elevation of the water's surface in the designated pool at the streamgaging station. The depth of the stream is not included in gauge height either.
Monitoring stations known as Federal Priority Streamgages (FPS) are used to track the volume of water in streams and rivers across the country and to fulfil one or more long-term, strategic information needs of the federal government.
The cross-sectional area of the channel is calculated by taking numerous discrete measurements of streamflow discharge using a velocimeter and a method for measuring the channel geometry.
There are four hash lines between the tenths that are used to measure hundredths of a foot. The bottom of the hash is another, and the top is one hundredth. 5 hundredths are represented by the pointed hash (0.05).
The foot and tenth labels above the water line, along with the hashes down for hundredths, are used to read the gauge.
The Global Stream gauge market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The majority of USGS streamgages are utilised year-round to produce continuous streamflow data. The National Streamflow Network is made up of all of these gauges put together.
However, some gauges merely capture a stream, lake, or reservoir's water level (also known as the gauge height or stage); streamflow (also known as discharge) is not calculated. When the requirement for or applicability of flow information is not present (lakes), these less expensive gauges are utilised to monitor trends in water levels.
Other streamgages, referred to as partial-record gauges, are only used and have their quality controlled for specific flow regimes like high flow, peak flow, low flow, etc. These streamgages contain crest-stage gauges, which are employed in investigations of flood frequency to determine the height of peak stages occurring at particular points in streams.
Seasonal streamgages, such as those that are only used during irrigation allocation season, are ones that are operated for a specific time of the water year. Rapid-deployment gauges (RDGs) are gauges that are rapidly mounted on buildings across streams and rivers (such as bridges) during emergencies to provide water level information when a streamgage is absent or damaged. A small group of streamgages known as supergages gather information on both streamflow and ongoing water quality.
A number of techniques can be used to determine stream stage. These techniques include the conventional float/stilling-well method as well as more modern ones that make use of pressure transducers, gas-purge systems, radar sensors, etc. Stream stage is typically stated in feet and tenths of a foot, metres and hundreds or thousands of a foot, or in feet and hundredths of a metre.
Although the USGS is primarily responsible for operating and maintaining the streamgages, the majority of them are sponsored in collaboration with one or more of the over 1,800 Federal, State, local, and Tribal agencies or organisations. This special collaboration produces impartial data that is consistent across the nation and helps local decision-making.
Due to the shared costs, a lot more streamgages are operated than would be possible with just USGS appropriations, which only cover about one-third of the required money.
These collaborations also make it possible to evenly spread fixed expenses, such as those related to infrastructure for data storage and distribution, which makes information streamlining more affordable for everyone.
One of the world's largest stream gaging operations is run by the USGS. More than 11,000 gauges detect water levels; the information is normally sent to USGS computers within an hour of the measurement.
For the majority of gauges, hourly (or more frequent) time series of streamflows are computed using continuously measured water levels from gauge-specific rating curves that were developed using onsite streamflow measurements taken by USGS hydrographersâmore than 80,000 onsite measurements are typically taken each year.
The statistics are published online with quality assurance. Emergency responders, water management, environmental and transportation organisations, universities, utilities, leisure enthusiasts, and consulting firms are just a few of the groups who use data.
