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.

Selected High-Water Marks along Pee Dee and Waccamaw Rivers, SC
Date Published: October 24, 2017
Status: Active

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.

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.

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...

Measuring streamflow, Georgia
Date Published: May 9, 2017

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.

Flood inundation mapping locations in North and South Carolina
Date Published: April 6, 2017

The U.S. Geological Survey (USGS) has created flood-inundation maps for selected streamgage sites in 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 a selected maximum water level. The inundated areas depicted on these maps are approximate, and accuracy of the maps is a function of the...

Date Published: February 17, 2017

The multiyear drought in North and South Carolina (summer 1998-fall 2002) brought wide recognition of the vulnerability of the water resources in these two States to climatic conditions. To prepare for drought conditions in the future, water managers and State and Federal water-resource agencies sought to develop tools to assess hydrologic conditions in both a predictive and responsive manner...
