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...

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-...

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development of total maximum daily loads (TMDLs) for streams, determining the quantity of water that can be safely withdrawn from a particular stream, and preparing the State Water Plan.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...
