Computation of low-flow statistics at continuous-record streamgages and regionalization of selected low-flow characteristics for streams in Georgia, South Carolina, and North Carolina
This ongoing USGS study for Georgia, South Carolina, and North Carolina aims to (1) compute low-flow statistics at selected continuous-record streamgages in Georgia, South Carolina, and North Carolina and to (2) develop regional regression equations for a subset of those low-flow characteristics for streams that are not substantially affected by tides, regulation, diversions, or other...
Norcross Urban Hydrology Unit
In the Atlanta metropolitan area, a hydrologic data-collection network has been established to collect real-time streamflow, precipitation, continuous and discrete water-quality data. The USGS South Atlantic Water Science Center (SAWSC) Urban Hydrology Unit (UHU), located in Norcross, Georgia, has been working in cooperation with local municipal and county agencies in and around the Atlanta...
South Carolina Flood Frequency Q&A
In 2015, Dr. Robert Holmes, USGS National Flood Hazard Coordinator, took time to discuss some issues related to the flooding in South Carolina following the Appalachian Floods and Hurricane Joaquin.
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.
Charlotte-Mecklenburg, N.C., Hydrologic Network
The U.S. Geological Survey (USGS) has been collecting streamflow data in North Carolina for more than 100 years. In the Charlotte and Mecklenburg County area, a hydrologic data-collection network has been established to collect not only streamflow data but also rainfall data. In response to the floods of August 1995 and July 1997, the U.S. Geological Survey Cooperative Water Program and Charlotte...
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...
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...
USGS Data Delivery Tools
USGS WaterAlert allows users to set notification thresholds for any USGS real-time stream or raingage, water-quality, or groundwater monitoring site and then sends emails or text messages to subscribers whenever the threshold conditions are met, as often as every hour.
StreamStats for Georgia, North and South Carolina
StreamStats is a map based Web application that provides information that can be used by engineers, managers, and planners to make informed decisions on water-related activities. Primary products are basin delineations, basin-characteristic measurements, and estimates of streamflow statistics. StreamStats allows for the analysis of upstream and downstream relations along streams.
Current and Historical Peak Stage Bar Graphs for North Carolina
Current and Historical Peak Stage Bar Graphs for North Carolina The Peak Stage Bar Graphs section for North Carolina allows you to compare current stream stage with historic peaks at water-monitoring sites throughout North Carolina.
Low-Flow Frequency and Flow Duration Statistics at Continuous-Record Gages in South Carolina
South Carolina State agencies use low-flow statistics for many applications, including determining waste-load allocations for point sources, development of total maximum daily loads (TMDLs) for streams, determining the quantity of water that can be safely withdrawn from a particular stream, and preparing the State Water Plan. This project will monitor the low-flow frequency and duration statistics...
