Heavy-Mineral Sand Resources in the Southeastern U.S.
We are assessing the extent of industrial mineral resources hosted by heavy-mineral sands in the coastal plain of the southeastern United States. “Heavy-mineral sands" (HMS) is a term commonly used in industry and geologic literature to describe layered sediments deposited in coastal environments that contain dense (“heavy") minerals of economic value. The heavy minerals extracted from these...

Scenario-Based Assessments for Coastal Change Hazard Forecasts
A decade of USGS research on storm-driven coastal change hazards has provided the data and modeling capabilities needed to identify areas of our coastline that are likely to experience extreme and potentially hazardous erosion during an extreme storm.
Long-Term Coastal Change
Goals of this task include developing and improving coastal-change assessments and supporting long-term planning and decision making to ensure sustainable coastal economies, infrastructure, and ecosystems.
National Assessment of Coastal Change Hazards
Research to identify areas that are most vulnerable to coastal change hazards including beach and dune erosion, long-term shoreline change, and sea-level rise.
Research and Investigations
The USGS South Atlantic Water Science Center (SAWSC) is comprised of water-science offices throughout Georgia, North Carolina and South Carolina.
The SAWSC conducts research and investigations related to topics such as groundwater and surface-water quality related to anthropogenic and agricultural activities, hydraulic and hydrologic modeling, tracking the...
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.

Hurricane Information for Georgia, North Carolina, and South Carolina.
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...
Hurricane and Flood Response Map Viewer
The USGS Flood Event Viewer (FEV) is the public data discovery component of the Short-Term Network (STN) database. Data viewable and downloadable from this page are from the STN database. This application integrates with the USGS National Water Information System (NWIS) database for display of time-series water data.
Structures Data
USGS data portray selected structures data, including the location and characteristics of manmade facilities. Characteristics consist of a structure's physical form (footprint), function, name, location, and detailed information about the structure. The types of structures collected are largely determined by the needs of the disaster planning and response and homeland security organizations....
Boundaries Data
Boundaries data or governmental units represent major civil areas including states, counties, Federal, and Native American lands, and incorporated places such as cities and towns.
Hydrography Data
The National Hydrography Dataset (NHD) and Watershed Boundary Dataset (WBD) are used to portray surface water on The National Map.
The United States Interagency Elevation Inventory (USIEI)
The USIEI is a comprehensive, nationwide listing of known high-accuracy topographic and bathymetric data for the United States and its territories. The project is a collaborative effort of the USGS and NOAA with contributions from other federal agencies. The inventory supports the 3D Elevation Program and the Integrated Ocean and Coastal Mapping effort. This resource is updated in Spring and...
Elevation Data
The 3DEP products and services available through The National Map consist of lidar point clouds (LPC), standard digital elevation models (DEMs) at various horizontal resolutions, elevation source and associated datasets, an elevation point query service and bulk point query service. All 3DEP products are available, free of charge and without use restrictions.
Orthoimagery Data
Orthoimagery data typically are high resolution aerial images that combine the visual attributes of an aerial photograph with the spatial accuracy and reliability of a planimetric map. The National Map offers public domain, 1-meter orthoimagery for the conterminous United States with many urban areas and other locations at 2-foot or finer resolution.
The National Map Small-Scale Collection
The National Map offers a collection of small-scale datasets, most of which are at 1:1,000,000. The National Map publishes two data collections at one million-scale: one for Global Map users and one for National Map users. In terms of vector geometry, the lines, points, and areas in these data collections are identical. The difference is in the attributes assigned to these features.
Science Data Integration and Delivery
Consistent synthesis, integration, storage, and availability of fundamental data is critical to meeting the needs of USGS Science. We develop databases for hydrography, topography, invasive species, water resources, and many other datasets utilized by resource managers.

A carbonatite here, a glacial moraine there, a zig-zagging fault or two, even a behemoth of a batholith. The geology of the 50 States is an enormous patchwork of varied forms, beautiful in their variance but challenging to present as a single map.

The heavy rains and storm surge Hurricane Matthew produced caused severe flooding in many parts of the south east, resulting in almost 40 peak flood records. As the flood waters continue to recede from some affected areas, the U. S. Geological Survey will continue its efforts to record this historic flooding.
