Brazilian Agencies Partner With USGS On Water Programs
The USGS International Programs Office has intermittently collaborated with Brazil's Geological Survey (CPRM) since the early 1970's. With the creation of the Brazilian National Water Agency (ANA), Brazil's hydrologic monitoring network has taken on a higher socioeconomic importance. The collaboration agreements between USGS and ANA/CPRM have strengthened the Brazilian streamgaging network as well...
SAWSC Monitoring of Hydrologic Hazards
A major element of the USGS mission is the documentation of the extent and magnitude of extreme hydrologic events, like floods and droughts. The South Atlantic Water Science Center is a leader in monitoring extreme water conditions, from droughts and falling groundwater levels to floods and storm-tide surges to water-quality problems.
Georgia Geologic Survey - Joint USGS and GGS Publications
The South Atlantic Water Science Center - Georgia Office cooperates with the Georgia Geologic Survey (GGS) in many hydrologic projects. A number of joint publications have been published over the years.
Hydroacoustic Applications: Technological Advancements in the Streamgaging Network
In the mid-1990s, a new technology emerged in the field of inland streamflow monitoring. The South Atlantic Water Science Center is making great use of the acoustic Doppler current profiler (ADCP). It was originally developed for oceanographic work, but was adapted for inland streamflow measurements. This instrument is transforming the U.S. Geological Survey (USGS) streamgaging program.

The Streamgaging Program in the South Atlantic Water Science Center
The U.S. Geological Survey (USGS) South Atlantic Water Science Center streamgage program is part of the nationwide program that provides streamflow information for a variety of purposes—including the protection of life and property, infrastructure design, recreational usage, and long-term trend assessment. This information is critical to resource managers, farmers, fishermen, kayakers, land-use...
The South Atlantic Water Science Center Thrives on Partnerships
Our Center is provided only about 30% of our total funds through direct appropriations. The rest must be obtained through cooperative partnerships between other Federal, State and Local agencies. We currently have more than 160 partnerships with various agencies across the three states. This unique business model means we must stay in touch with the local science issues and our cooperator's needs...
USGS Long-Term Water Monitoring Networks
“USGS long-term streamgages and groundwater wells are like a fine wine…they get better with age!” The accurate, long-term monitoring networks of SAWSC provide valuable data in real-time and historical perspective to compare that data to. The longer a monitoring location is in operation, the more valuable it becomes, since more statistical comparisons can be performed. Our field technicians...
Epic September 2009 Flooding - Georgia
Many days of continuous heavy rain in mid-September 2009 resulted in flooding in many parts of Georgia, especially in north Georgia and the Atlanta region. The rains produced streamflows of record proportions. rivers and streams had magnitudes so great that the odds of it happening were less than 0.2 percent in any given year. In other words, there was less than a 1 in 500 chance that parts of...
