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.
Located in South Central Texas, the Edwards Aquifer encompasses an area of approximately 4,350 square miles (11,300 km 2) that extends into parts of 11 counties. [3] The aquifer's boundaries begin at the groundwater divide in Kinney County, East of Brackettville, and extend Eastward through the San Antonio area and then Northeast where the aquifer boundary ends at the Leon River in Bell County ...
The Rio Grande Compact Commission, located in El Paso, Texas, administers the Rio Grande Compact. An employee of the USGS New Mexico Water Science Center serves as Secretary to the Compact. The principal duty of the Secretary is to compile streamflow and storage data used in the annual accounting computations performed by the commission's ...
A USGS gauging station on the Scioto River below O'Shaughnessy Dam near Dublin, Ohio. The USGS operates the streamgaging network for the United States, with over 7400 streamgages. Real-time streamflow data [17] are available online.
The list of rivers of Texas is a list of all named waterways, including rivers and streams that partially pass through or are entirely located within the U.S. state of Texas. Across the state, there are 3,700 named streams and 15 major rivers accounting for over 191,000 mi (307,000 km) of waterways.
In fiscal year 2008, the USGS provided 35% of the funding for everyday operation and maintenance of gauges. [8] 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 ...
Within the USGS, the Water Resources Division carries the responsibility for monitoring water resources. To establish a stream gauge, USGS personnel first choose a site on a stream where the geometry is relatively stable and there is a suitable location to make discrete direct measurements of streamflow using specialized equipment.
A stream hydrograph is commonly determining the influence of different hydrologic processes on discharge from the subject catchment. Because the timing, magnitude, and duration of groundwater return flow differs so greatly from that of direct runoff, separating and understanding the influence of these distinct processes is key to analyzing and simulating the likely hydrologic effects of ...
