This modification - supplied by the USGS Hydrologic Instrumentation Facility - is available in two sizes: the original 3" and the recently added 6". [28] Kilpatrick notes that the discharge for this modification of the Parshall flume is slightly greater than for a standard Parshall flume of the same size. [29]
Infographic explaining the hierarchy of the United States hydrologic unit system. Originally a four-tier system divided into regions, sub-regions, accounting units, and cataloging units, each unit was assigned a unique Hydrologic Unit Code (HUC). As first implemented the system had 21 regions, 221 subregions, 378 accounting units, and 2,264 ...

The building was built in part to embody the Survey's mission. Notably, the main tower’s eight-pointed star shape symbolizes the cardinal points of a ...
The Center for Earth Resources Observation and Science (EROS) is a United States Geological Survey data management, systems development, and research field center It serves as the national archive of remotely sensed images of the Earth's land surface acquired by civilian satellites and aircraft.
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.
The first version of SDI-12 was released in 1988. It was designed by a coalition which included the U.S. Geological Survey's Hydrologic Instrumentation Facility (HIF) and a group of private companies. [2] The SDI-12 Specification is maintained by a non-profit corporation called the SDI-12 Support Group.
