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.
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 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...

The National Water Information System (NWIS) Mapper provides access to water-resources data at over 1.5 million sites across the U.S., including current and historical data. Users can search by site type, data type, site number, or place.
Information and products are organized within three coastal change hazard themes: 1) extreme storms, 2) shoreline change, and 3) sea-level rise. Each data item represents an individual research product, with some items grouped together as aggregates to show the breadth of the topic and make it easy to explore.
Real-time, daily, peak-flow, field measurements, and statistics of current and historical data that describe stream levels, streamflow (discharge), reservoir and lake levels, surface-water quality, and rainfall in Georgia, South Carolina, and North Carolina.
Data from wells, springs, test holes, tunnels, drains, and excavations in Georgia, South Carolina, and North Carolina; well location data includes information such as latitude and longitude, well depth, and aquifer. Current and historical observations, and daily data are offered.
Chemical, physical, and biological properties of water, sediment, and tissue samples from Georgia, South Carolina, and North Carolina. Water-quality data are collected as either discrete field measurements or as continuous time-series data from automated recorders.
Data from rain gages that provide real-time data are relayed to the USGS and are transmitted from each station at intervals of 1 to 8 hours. Real-time data available on these web pages are provisional data that have not been reviewed or edited.
Water-use data are collected by area type (state, county, watershed, or aquifer) and source (rivers or groundwater), and category (such as public supply or irrigation). Water-use data has been reported every five years since 1950. The USGS works with local, State, and Federal agencies as well as other organizations to collect and report withdrawals.
WaterWatch is a U.S. Geological Survey Web site that displays maps, graphs, and tables describing real-time, recent, and past streamflow conditions for the United States. The real-time information generally is updated on an hourly basis.
The U.S. Geological Survey has a database/archive of about 850,000 wells across the Nation. A well with below normal groundwater levels is identified when the most recent water-level measurement is in the 24th percentile or lower in the month of measurement over the period of record for the well.
The New Hope arm of Jordan Lake, located in Chatham County, North Carolina, serves as a drinking-water supply for the Towns of Cary, Apex, and Morrisville. The reservoir is listed as impaired due to nutrient over-enrichment and occasionally experiences algal blooms and fish kills.

Coastal communities count on beaches for recreation and for protection from large waves, but beaches are vulnerable to threats such as erosion by storms and flooding. Whether beaches grow, shrink, or even disappear depends in part on what happens just offshore. How do features like shifting sandbars affect waves, currents, and the movement of sand from the beach to offshore and back?
