North Carolina Flood Frequency Statistics
Note: This section of the website is still under construction
Reliable estimates of the magnitude and frequency of floods are needed for numerous design and management functions throughout North Carolina. For U.S. Geological Survey (USGS) streamgage sites, where more than 10 years of annual peak-flow data have been recorded, estimates of flood frequency can be computed using statistical analysis. Flood-frequency estimates at gaged sites can be regionalized, or extended in space, to develop estimates of flood-frequency at ungaged sites. A web page is being developed in cooperation with the North Carolina Department of Transportation (NCDOT) to allow users to select a specific ungaged stream site to obtain location, site information, and predictive equations that can be used to calculate the t-year flood-frequency estimates.
