Flood-Inundation mapping in Georgia, North and South Carolina

The U.S. Geological Survey (USGS) has created flood-inundation maps for selected streamgage sites in Georgia, North and South Carolina. These maps depict the approximate area that would be inundated at selected water levels, ranging from approximately top-of-bank to the maximum observed water level. The inundated areas depicted on these maps are approximate, and accuracy of the maps is a...

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.

Quantifying Floodplain Ecological Processes and Ecosystem Services in the Delaware River Watershed

Floodplain and wetland areas provide critical ecosystem services to local and downstream communities by retaining sediments, nutrients, and floodwaters. The loss of floodplain functionality due to land use conversion and degradation reduces the provisioning of these services. Assessing, quantifying, and valuing floodplain ecosystem services provide a framework to estimate how floodplain...

Collection of High-Water Mark Data at Selected Roadway Crossings To Document October 2016 Flooding in the Pee Dee and Waccamaw River Basins of South Carolina

Hurricane Matthew generated large amounts of rainfall in South and North Carolina during September/October 2016. The South Atlantic Water Science Center, in cooperation with the South Carolina Department of Transportation, recorded High-Water Marks along selected road crossings, within the Pee Dee and Waccamaw River Basins of South Carolina.

South Atlantic Water Science Center Drought Monitoring

When rainfall is less than normal for several weeks, months, or years, the flow of streams and rivers declines, water levels in lakes and reservoirs fall, and the depth to water in wells increases. If dry weather persists and water-supply problems develop, the dry period can become a drought.

South Atlantic Water Science Center Storm-Tide Monitoring

Preventing flood hazards, such as the hurricane induced storm surge, from becoming human disasters requires an understanding of the relative risks floods pose to specific communities and knowledge of the processes by which flood waters rise, converge, and abate. Historically, hurricane-induced storm tides have been documented through measurement of high-water marks left on structures or...

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-...
