What is streamflow data?
Streamflow or discharge is the volume of water moving past a fixed location on a river in a unit of time, commonly expressed as cubic feet per second or cubic meters per second. Indirect methods are used primarily to measure the peak discharge from a flood event after the flood has passed and the stage has receded.
What stats USGS stream?
StreamStats is a Web-based tool that provides streamflow statistics, drainage-basin characteristics, and other information for USGS streamgaging stations and for user-selected ungaged sites on streams.
What are streamflow conditions?
Streamflow, or channel runoff, is the flow of water in streams, rivers, and other channels, and is a major element of the water cycle. The record of flow over time is called a hydrograph. Flooding occurs when the volume of water exceeds the capacity of the channel.
What is StreamStats?
StreamStats is a Web application that provides access to an assortment of Geographic Information Systems (GIS) analytical tools that are useful for water-resources planning and management, and for engineering and design purposes.
How are streamflow statistics used in the US?
The U.S. Geological Survey (USGS) develops and publishes regression equations for estimating streamflow statistics for every State, the Commonwealth of Puerto Rico, and a number of metropolitan areas in the United States. These equations have been compiled into the National Streamflow Statistics (NSS) Program.
What do you need to know about streamstats?
StreamStats is a Web-based geographic information system application that provides users with access to basin and streamflow characteristics for gaged and ungaged streams. StreamStats is a Web application for water-resources planning and engineering purposes.
What kind of equations are used for stream flow?
Equations are available for estimating other statistics, such as the mean annual flow, monthly mean flows, flow-duration percentiles, and low-flow frequencies (such as the 7-day, 10-year low flow (7Q10)) for many of the states.
How many streams are monitored by the USGS?
The USGS works in partnership with more than 1,885 Federal, regional, State, Tribal, and local agencies or organizations to maintain and manage a multipurpose network of streamgages that monitor streamflow and (or) water level.
