Reliable estimates of the magnitude and frequency of floods are part of the technically-based framework for hydraulic-structure design and flood-plain delineation in South Carolina, North Carolina, and Georgia. Annual peak flows measured at U.S. Geological Survey (USGS) streamflow gaging stations (stations) are used to compute flood frequency estimates for a location on a stream. However, such estimates also are needed at ungaged stream locations. A process known as regionalization is used to estimate the magnitude and frequency of floods for ungaged locations. Regionalization combines at-site flood-frequency estimates from a group of stations within a hydrologic region and selected basin characteristics to form the basis of estimates for ungaged stream locations within that region.

Magnitude and Frequency of Rural Floods in the Southeastern United States, through 2006: Volume 2, North Carolina
Reliable estimates of the magnitude and frequency of floods are required for the economical and safe design of transportation and water-conveyance structures. A multistate approach was used to update methods for estimating the magnitude and frequency of floods in rural, ungaged basins in North Carolina, South Carolina, and Georgia that are not substantially affected by regulation, tidal fluctuatioAuthorsJ.
