Selected High-Water Marks along Pee Dee and Waccamaw Rivers, SC
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.

June 4, 2017
Status: Active

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...

Flood inundation mapping locations in North and South Carolina
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...
